| [nitrogen metabolism in growing swine receiving a bacterial protein supplement (alcaligenes eutrophus) instead of soybean meal]. | in a balance trial with 10 pigs (mean body mass 50 kg) the influence of a bacterial protein supplement (alcaligenes eutrophus) on n-metabolism was investigated. the bacteria were included into the diet at levels of 7 and 14% at the expense of extracted soyabean meal. thus bacterial "pure protein" (bacterial non-nucleic acid n x x 6.25) amounted to 30 and 60% of the protein of the ration. consuming 2 kg of feed dry matter per day the animals of the control group (i) and the experimental groups (i ... | 1984 | 6539585 |
| pseudomonas stutzeri and related species undergo natural transformation. | cells of pseudomonas stutzeri are naturally transformed by homologous chromosomal dna; they do not require chemical treatment to become competent. this capacity to undergo natural transformation was found to be shared by the closely related species p. mendocina, p. alcaligenes, and p. pseudoalcaligenes, but was not detectable in strains of p. aeruginosa, p. perfectomarinus, p. putida, p. fluorescens, or p. syringae. p. stutzeri could be transformed either on plates or in liquid medium. only doub ... | 1983 | 6571730 |
| comparative susceptibilities of organisms isolated in sicily to cefotetan and other antibiotics. | in recent years there has been a gradual increase in the number of infections caused by klebsiella, enterobacter and serratia and non-fermentative bacilli such as pseudomonas, alcaligenes and acinetobacter. the object of this investigation was to evaluate the antibacterial properties of the cephalosporins cefoxitin, cefoperazone, cefotaxime and of gentamicin, in comparison with cefotetan, a new cephamycin with a high degree of stability to beta-lactamases. the cefotetan mic was not affected eith ... | 1983 | 6573327 |
| [bacterial formate dehydrogenase. substrate specificity and kinetic mechanism of s-formyl glutathione oxidation]. | the substrate specificity of nad-dependent formate dehydrogenase from the methylotrophic bacterium achromobacter parvulus t1 was studied. the kinetic mechanism of s-formyl glutathione oxidation was determined. the initial velocity studies and inhibition analysis were carried out. it was shown that the kinetic mechanism for the enzyme with s-formyl glutathione as a substrate is similar to that with formate and is rapid-equilibrium random. using independent methods, it was found that formate dehyd ... | 1983 | 6615926 |
| pathogenesis of change in the upper respiratory tracts of turkeys experimentally infected with an alcaligenes faecalis isolate. | the course of changes within the upper respiratory tracts of turkey poults experimentally infected with alcaligenes faecalis was studied. the initial change observed (5 days post-inoculation) was colonization of the upper respiratory tract by the bacterium. changes in the nasal turbinates and trachea were first apparent as a focal loss of cilia but subsequently developed into a general loss of cilia (11 days post-inoculation). eventually, the entire ciliated epithelial layer in the cranial regio ... | 1983 | 6618668 |
| microbial growth associated with granular activated carbon in a pilot water treatment facility. | the microbial dynamics associated with granular activated carbon (gac) in a pilot water treatment plant were investigated over a period of 16 months. microbial populations were monitored in the influent and effluent waters and on the gac particles by means of total plate counts and atp assays. microbial populations between the influent and effluent waters of the gac columns generally increased, indicating microbial growth. the dominant genera of microorganisms isolated from interstitial waters a ... | 1983 | 6625567 |
| an extracellular d(-)-3-hydroxybutyrate oligomer hydrolase from alcaligenes faecalis. | a strain of alcaligenes faecalis secretes an extracellular d(-)-3-hydroxybutyrate oligomer hydrolase, in addition to poly(3-hydroxybutyrate) depolymerase, when it is grown in a medium containing poly(3-hydroxybutyrate) as the sole carbon source. the oligomer hydrolase (ec 3.1.1.22), which has been purified to electrophoretic homogeneity, has a molecular weight of 68 000, as estimated by sephadex g-100 gel filtration, and of 74 000, by polyacrylamide gel electrophoresis in the presence of sodium ... | 1983 | 6626560 |
| properties and roles of bacterial symbionts of polyvinyl alcohol-utilizing mixed cultures. | from several polyvinyl alcohol (pva)-utilizing mixed cultures, two component bacterial strains essential for pva utilization were isolated, and their properties and roles in pva utilization were studied. each pair of essential component strains consisted of a type i strain, which produced a pva-degrading enzyme and constituted the predominant population of the mixed culture in pva, and a type ii strain, which produced a certain growth stimulant for the former strain. all of the type i strains we ... | 1983 | 6639015 |
| [taxonomic study of free nitrogen-fixing bacteria isolated from the endorhizosphere of rice]. | twenty strains of free-living n2-fixing bacteria, isolated from the endorhizosphere of rice in rice soils of senegal, were studied on the basis of 259 morphological, physiological, biochemical and nutritional characters. half of them were gram-negative small rods with polar flagella and showing a strictly respiratory metabolism; they were characteristic of the genus pseudomonas. a first group of 6 strains was related to the p. cepacia-p. marginata group characterized by lophotrichous flagella; t ... | 1983 | 6651126 |
| degradation of chlorophenols by a defined mixed microbial community. | synthetic sewage containing phenol, acetone, and alkanols plus 4-chlorophenol or a mixture of isomeric chlorophenols is completely degraded by a defined mixed culture with pseudomonas sp. strain b13 as a chlorocatechol-dissimilating member of the community. total degradation of the organic carbon was indicated by release of stoichiometric amounts of chloride and low content of dissolved organic carbon in the cell-free effluents. during adaptation to high loads of chlorophenols the initial meta-c ... | 1983 | 6651293 |
| studies on the use of a long-acting oxytetracycline in turkeys: efficacy against experimental infections with alcaligenes faecalis and pasteurella multocida. | a group of 2-week-old turkey poults was inoculated with a pathogenic strain of alcaligenes faecalis. one week later, half the group was injected with a long-acting oxytetracycline formulation. poults were examined post-mortem on days 3, 5, and 10 post-treatment. swabs were taken of the trachea, sinus, and lung of each poult. poults were observed closely for clinical signs, and appropriate tissues were taken for histopathology. results showed no evidence of therapeutic effect on a. faecalis infec ... | 1983 | 6651700 |
| in vitro cytotoxicity of an alcaligenes faecalis and its relationship in in vivo tracheal pathologic changes in turkeys. | two isolates of alcaligenes faecalis from turkeys with respiratory disease were indistinguishable physically, biochemically, and for specific agglutinating antibodies. the isolates differed in in vitro cytotoxicity for turkey tracheal organ cultures and in ability to induce clinical rhinotracheitis in poults. the isolate designated ncdp induced in vitro cytotoxic changes in turkey tracheal organ cultures. additionally, poults inoculated with ncdp developed severe clinical signs of rhinotracheiti ... | 1983 | 6651702 |
| presence of a new cytochrome b - like pigment with a peak at 567 nm in various aerobic bacteria. | several physiological groups of bacteria were examined for the presence of a cytochrome b - like pigment which is demonstrable in dithionite-reduced minus substrate-reduced difference spectra. this pigment is characterized by an unusually high alpha band at 567 nm, a low concentration relative to conventional cytochromes, and an inability to be fully reduced by endogenous substrates or nadh. previous studies with one denitrifying and nondenitrifying species of the genus pseudomonas, in paracoccu ... | 1983 | 6652580 |
| comparative study of antitumor activity and immunomodulatory effect of tetrahydro-2-furanyl and tetrahydro-2-pyranyl (1 leads to 3)-beta-d-glucans. | the effects of tetrahydro-2-furanyl- and tetrahydro-2-pyranyl-ethers of (1 leads to 3)-beta-d-glucans from alcaligenes faecalis var. myxogenes (ifo 13140) on the activities of macrophages and natural killer (nk) cells in either icr or balb/c mice were studied. the derivatives with strong antitumor activity against sarcoma 180 in icr mice induced higher macrophage tumoricidal activity (greater than 40%) than those with low antitumor activity (less than 20%). all derivatives with high or low antit ... | 1983 | 6655547 |

| histamine-sensitizing factor of alcaligenes faecalis. | alcaligenes faecalis produced a histamine-sensitizing factor (hsf) in turkey poults and mice, which was detected in poults by an infraorbital sinus test and passive cutaneous anaphylaxis test and in mice by a rectal-temperature differential test. the a. faecalis hsf appeared to be similar to that produced by the genus bordetella and may be partly responsible for the clinical signs of alcaligenes rhinotracheitis in young poults. | 1983 | 6682654 |
| the pathology of an epizootic of acquired immunodeficiency in rhesus macaques. | a syndrome of acquired immunodeficiency within a group of outdoor-housed rhesus macaques (macaca mulatta) with unusually high mortality has been identified at the california primate research center. the cause of death for most of the affected animals included septicemia and/or chronic diarrhea with wasting, often complicated by other problems. in many cases, multiple or unusual infectious agents were isolated or recognized, including cytomegalovirus, cryptosporidium spp., and candida albicans. s ... | 1984 | 6691418 |
| phagocytosis of the legionnaires' disease bacterium (legionella pneumophila) occurs by a novel mechanism: engulfment within a pseudopod coil. | phagocytosis of legionella pneumophila, a bacterial pathogen that multiplies intracellularly in human mononuclear phagocytes and causes legionnaires' disease, occurs by a novel mechanism. a phagocyte pseudopod coils around the bacterium as the organism is internalized. human monocytes, alveolar macrophages, and polymorphonuclear leukocytes all phagocytize l. pneumophila by this unusual process, termed "coiling phagocytosis," and these leukocytes phagocytize not only live l. pneumophila in this w ... | 1984 | 6692469 |
| response of marine bacterioplankton to differential filtration and confinement. | the bacterioplankton community of confined seawater at 25 degrees c changed significantly within 16 h of collection. confinement increased cfu, total cell number (by epifluorescence microscopy), and average cell volume of bacterioplankton and increased the turnover rate of amino acids in seawater sampled at frying pan shoals, n.c. the bacterioplankton community was characterized by two components: differential doubling times during confinement shifted dominance from bacteria which were noncultur ... | 1984 | 6696422 |
| ornithine-containing lipids in thiobacillus a2 and achromobacter sp. | 20 bacterial strains (corresponding to 16 species) were screened for ornithine lipids. only two species (thiobacillus a2 and achromobacter sp.) turned out to contain ornithine lipids (2.71 mmol/100 g and 0.38 mmol/100 g bacterial dry weight, respectively). in both ornithine lipids, a 3-hydroxy fatty acid was amide-linked to the alpha-amino group of ornithine, a normal fatty acid was ester-linked to the 3-hydroxy group of the former. the predominant fatty acids were 18:1(11) and 3-hydroxy-20:1(13 ... | 1984 | 6698001 |
| nosocomial colonization and infection by achromobacter xylosoxidans. | achromobacter xylosoxidans, a bacterial species named in 1971, is often isolated from aqueous environments, but little has been reported about its pathogenicity in humans, its epidemiological pattern, and its susceptibility to antibiotics and antiseptics. we were faced with an epidemic caused by this microorganism for 18 months in an intensive care unit. two patients had fatal infections and 37 others were colonized. the source was the deionized water of the hemodialysis system. the 46 isolates ... | 1984 | 6699141 |
| small angle x-ray study on the structure of active and inactive ribulose bisphosphate carboxylase from alcaligenes eutrophus. evidence for a configurational change. | two small angle x-ray scattering curves have been obtained from active and inactive ribulose 1,5-bisphosphate carboxylase from alcaligenes eutrophus. the radius of gyration was calculated to be r = 47.8 +/- 0.1 nm for the active enzyme and r = 49.2 +/- 0.1 nm for the inactive enzyme. the maximum particle dimension amounts to 13.5 +/- 0.5 nm for the active and 15.7 +/- 0.5 nm for the inactive enzyme. a model of the active carboxylase is presented. it is in good agreement with models derived from ... | 1984 | 6707014 |
| cleavage of formate from omega,4-dihydroxyacetophenone. an unusual oxygen-requiring reaction in the bacterial catabolism of 4-hydroxyacetophenone. | an enzyme, from a soil bacterium grown on 4-hydroxyacetophenone, cleaved the side chain of omega,4-dihydroxyacetophenone between the keto group and the carbon atom bearing a hydroxy group to give 4-hydroxybenzoate and formate. the reaction was o2-dependent. partially purified enzyme required no added cofactors for activity. | 1984 | 6712612 |
| differentiation of alcaligenes-like bacteria of avian origin and comparison with alcaligenes spp. reference strains. | although standard biochemical tests used for the identification of alcaligenes spp. revealed only minor differences, the oxidative low-peptone technique clearly differentiated between alcaligenes-like bacteria of avian origin and alcaligenes spp. reference strains. based on their colonial morphology, biochemical profiles, and hemagglutination, the alcaligenes-like bacteria of avian origin were further divided into two subgroups, c1-t1 and c2-t2. colonies of subgroup c1-t1 were nondescript, round ... | 1984 | 6715517 |
| heterotrophic nitrification among denitrifiers. | twelve denitrifying bacteria representing six genera were tested for an ability to nitrify pyruvic oxime heterotrophically. six of these bacteria exhibited appreciable nitrification activity, yielding as much as 5.8 mm nitrite and little or no nitrate when grown in a mineral salts medium containing 7 mm pyruvic oxime and 0.05% yeast extract. of the six active bacteria, four (pseudomonas denitrificans, pseudomonas aeruginosa, and two strains of pseudomonas fluorescens) could grow on yeast extract ... | 1984 | 6721486 |
| bactericidal activity of ethanol against glucose nonfermentative gram-negative bacilli. | the bactericidal effect of ethanol on glucose nonfermentative gram-negative bacilli (nonfermentative bacilli) and other species of micro-organisms was studied with emphasis on the former. at 20 degrees c, 10 to 20% v/v ethanol took 1 h or more to kill thirteen strains of nonfermentative bacilli while 40 to 99.5% concentrations produced a bactericidal effect within 1 min of exposure. eleven strains of glucose fermentative organisms showed a similar tendency to that noted with nonfermentative baci ... | 1984 | 6727697 |
| corneal ulcer due to achromobacter xylosoxidans. | we report a case of corneal ulcer caused by the opportunistic organism achromobacter xylosoxidans which developed during chronic topical steroid treatment of an eye with neovascular glaucoma. a. xylosoxidans has probably been underreported as a cause of ocular infection because of confusion between this organism and other gram-negative organisms, particularly pseudomonas. a. xylosoxidans is resistant to aminoglycosides and some cephalosporins but not carbenicillin. this difference in antibiotic ... | 1984 | 6733072 |
| microbial biodegradation of 4-chlorobiphenyl, a model compound of chlorinated biphenyls. | the biodegradation products of 4-chlorobiphenyl were analyzed in an achromobacter sp. strain and a bacillus brevis strain. both strains generated the same metabolites, with 4-chlorobenzoic acid as the major metabolic product. our results corroborate previous observations whereby most bacterial strains degrade the chlorobiphenyls via a major pathway which proceeds by an hydroxylation in position 2,3 and a meta-1,2 fission. however, we also detected several metabolites whose structure suggests the ... | 1984 | 6742836 |
| different local therapeutic effects of various polysaccharides on mh134 hepatoma in mice and its relation to inflammation induced by the polysaccharides. | the local antitumor activities and inflammation-inducing activities of various antitumor polysaccharides were examined and the relation between the two types of activity was studied. the tested antitumor polysaccharides included mg (a mannoglucan prepared from the culture fluid of microellobosporia grisea), lentinan, bacterial lipopolysaccharide, tak (a glucan from alcaligenes faecalis) and their derivatives. local antitumor activity was tested by intratumoral administration of the polysaccharid ... | 1984 | 6745566 |
| nickel in the catalytically active hydrogenase of alcaligenes eutrophus. | nickel is a constituent of soluble and particulate hydrogenase of alcaligenes eutrophus. incorporation of 63ni2+ revealed that almost the total nickel taken up by the cells was bound to the protein. chromatography of a crude extract on diethylaminoethyl cellulose demonstrated an association of 63ni2+ with soluble and particulate hydrogenase, supported by further analysis like polyacrylamide gel electrophoresis. unspecific binding of 63ni2+ to the protein was excluded by comparison with a mutant ... | 1982 | 6749813 |
| the n/f and oxi/ferm systems for identification of oxidative-fermentative gram-negative rods: a comparative study. | two commercial systems, the flow n/f system and the roche oxi/ferm tube for identification of oxidative-fermentative gram-negative rods were compared. both systems were easy to use, but several reactions in both kits were sometimes difficult to interpret. of 53 reference strains, 70 per cent were identified correctly by the n/f system, whereas the oxi/ferm tube identified 43 per cent. incorrect identities were obtained in 9 per cent and 26 per cent of cases by the n/f and oxi/ferm kits respectiv ... | 1982 | 6756031 |
| [bacterial reductive transformation of aromatic nitro compounds]. | the transformation of 2,4,6-trinitrotoluene (tnt) and other aromatic nitro compounds by bacteria was studied in the course of their growth in a medium containing glucose. various bacteria were found, for the first time, to be capable of growth in the presence of 200 mg/l of tnt and of transformation of the compound with a higher or lesser activity. the results indicate that gram-negative bacteria play a key role in tnt transformation under natural conditions. the nitro group reduction is the pri ... | 1982 | 6757678 |
| accuracy of a rapid carbohydrate oxidation microtube method for identification of nonfermentative gram-negative bacilli. | a rapid carbohydrate oxidation microtube system (carr microbiologicals, wichita, kans.), designed for detecting the saccharolytic activity of gram-negative, nonfermenting bacilli, was evaluated and compared with the conventional oxidation-fermentation method. the oxidation of glucose, maltose, lactose, and xylose was tested with 430 strains of pseudomonas, acinetobacter, achromobacter, alcaligenes, moraxella, flavobacterium, and bordetella species. more than 95% of the isolates tested gave corre ... | 1982 | 6764775 |

| nickel requirement for active hydrogenase formation in alcaligenes eutrophus. | the nickel-dependent chemolithoautotrophic growth of alcaligenes eutrophus is apparently due to a requirement of nickel for active hydrogenase formation. cells grown heterotrophically with fructose and glycerol revealed a specific activity of soluble and membrane-bound hydrogenase which was severalfold higher than the normal autotrophic level. the omission of nickel from the medium did not affect heterotrophic growth, but the soluble hydrogenase activity was reduced significantly. in the presenc ... | 1981 | 6782086 |
| alcaligenes odorans, var. viridans as a hospital infectant. | the hazards of acquiring a nosocomial infection are significant even in modern hospitals in spite of aseptic procedures and antibiotics. in order to prevent or stop a hospital epidemic it is necessary to know or to recognize the infective agent, its source and its way of spreading. this is not always easy, esp. with some potential pathogens which are frequently found in the pathological materials as well as in the hospital environment. in the described series of hospital spread of alcaligenes od ... | 1981 | 6784393 |
| in vivo inactivation of soluble hydrogenase of alcaligenes eutrophus. | the soluble, nad+-reducing hydrogenase in intact cells of alcaligenes eutrophus was inactivated by oxygen when electron donors such as hydrogen or pyruvate were available. the sole presence of either oxygen or oxidizable substrates did not lead to inactivation of the enzyme. inactivation occurred similarly under autotrophic growth conditions with hydrogen, oxygen and carbon dioxide. the inactivation followed first order reaction kinetics, and the half-life of the enzyme in cells exposed to a gas ... | 1981 | 6786248 |
| naturally occurring genetic transfer of hydrogen-oxidizing ability between strains of alcaligenes eutrophus. | mutants defective in chemolithoautotrophic growth (aut-) have been isolated from alcaligenes eutrophus strains h16, n9a, g27, and tf93. spontaneous aut- mutants were obtained only with strain tf93. mutants of the other strains were selected after conventional mutagenesis or treatment with mitomycin. most of the mutants, including the spontaneous aut- strains, lacked hydrogenase activity (hox-) but possessed the ability to fix carbon dioxide (cfx+). agar mating of a. eutrophus h16 with hox- mutan ... | 1981 | 6787025 |
| improvement in the persistence of microbial asparaginase and glutaminase in the circulation of the rat by chemical modifications. | three enzymes used in cancer chemotherapy (asparaginases from escherichia coli and erwinia carotovora and glutaminase from achromobacter) were each reacted with four amino specific reagents (ethyl acetimidate, o-methylisourea, succinic anhydride, and formaldehyde/sodium borohydride). the half-lives of the modified enzymes measured in the blood of rats showed that guanidation, acetimidation and reductive alkylation were more likely to increase the persistence of the native enzymes than succinylat ... | 1981 | 6794649 |
| depression of hydrogenase during limitation of electron donors and derepression of ribulosebisphosphate carboxylase during carbon limitation of alcaligenes eutrophus. | alcaligenes eutrophus did not form the key enzymes of autotrophic metabolism, the soluble and particulate hydrogenases and ribulosebisphosphate carboxylase (rubpc), during heterotrophic growth on succinate in batch cultures. during succinate-limited growth in a chemostat, high activities of both hydrogenases were observed. with decreasing dilution rate (d) the steady-state hydrogenase activity (h) followed first-order kinetics, expressed as follows: h = hmax .e-alpha.d. an identical correlation ... | 1982 | 6798017 |

| influence of the activation state on the sedimentation properties of ribulose bisphosphate carboxylase from alcaligenes eutrophus. | ribulose-1,5-bisphosphate carboxylase from the chemolithotrophic hydrogen bacterium alcaligenes eutrophus was maximally active in the presence of 50 mm hco3- plus 10 mm mg2+. deactivation occurred upon removal of these ions. reactivation was achieved by incubation of the enzymes with hco3- plus mg2+. the concentration of hco3- (co2) required for half-maximal activation was 1.84 nm (0.064 mm). sedimentation velocity studies revealed that activation/deactivation is associated with drastic changes ... | 1982 | 6811588 |
| chemical modification of lysine residues in bacterial formate dehydrogenase. | specific modification of 4.4 lysine residues per molecule of formate dehydrogenase, from the methylotrophic bacterium achromobacter parvulus i by pyridoxal, results in complete inactivation of the enzyme. the concentration effect of the modifying agent and substrates on the inactivation of formate dehydrogenase has been studied. coenzymes do not protect the enzyme from inactivation. complete maintenance of enzyme activity was achieved in the presence of saturating concentrations of the formate a ... | 1982 | 6817795 |
| the pathway of nitrogen and reductive enzymes of denitrification. | some recent studies on the pathway of nitrogen and the reductases of denitrification are reviewed. the available evidence suggests that while the intermediates of denitrification can remain enzyme-bound (presumably to nitrite reductase) prior to formation of n2o, no and nitroxyl (hno) can be released in part by certain bacteria. release of no is recognized by a nitrite/no-15n exchange reaction and isotopic scrambling in product n2o; release of nitroxyl by pseudomonas stutzeri is recognized by is ... | 1982 | 6820251 |
| pseudomonas alcaligenes endocarditis. | pseudomonas alcaligenes is a common soil and water inhabitant that has rarely been proven a human pathogen. we describe a fatal case of pseudomonas alcaligenes endocarditis. the need for accurate identification of unusual organisms isolated in a clinical setting are discussed. | 1983 | 6823910 |
| cell-surface collagen-binding protein in the procaryote achromobacter iophagus. | collagen and its high-molecular-weight fragments specifically induce an extracellular collagenase (ec 3.4.24.8) in the gram-negative achromobacter iophagus. during the induction process the inducer is concentrated on the bacterial outer membrane. two-dimensional electrophoresis of 125i-labelled outer membrane proteins has shown that, in particular, the amount of one protein which is already present on the surface of non-induced bacteria increases quantitatively when the inducer is added. after 1 ... | 1983 | 6824647 |
