| microbial metabolism of pyridinium compounds. radioisotope studies of the metabolic fat of 4-carboxy-1-methylpyridinium chloride. | extracts of achromobacter d formed co(2), methylamine, succinate and formate as metabolic end-products from n-methylisonicotinic acid (4-carboxy-1-methylpyridinium chloride). the origin of the co(2) in the 4-carboxyl group and of the methylamine in the n-methyl group of n-methylisonicotinate was demonstrated with carboxyl-(14)c- and n-me-(14)c-labelled substrates respectively. the carbon skeletons of formate and succinate were shown to arise from the c-2 and the c-3-c-6 atoms of the heterocyclic ... | 1972 | 4634828 |

| microbial metabolism of amino alcohols. 1-aminopropan-2-ol and ethanolamine metabolism via propionaldehyde and acetaldehyde in a species of pseudomonas. | 1. growth and manometric experiments showed that a pseudomonas sp. p6 (n.c.i.b. 10431), formerly known as achromobacter sp. p6, was capable of growth on both stereoisomers of 1-aminopropan-2-ol, and supported the hypothesis that assimilation involved metabolism to propionaldehyde, propionate and possibly 2-hydroxyglutarate. a number of alternative intermediary metabolites were ruled out. 2. accumulation of propionaldehyde from 1-aminopropan-2-ol by intact cells occurred only during active growth ... | 1973 | 4723219 |

| bactericidal properties of tego 103 s and tego 103 g. | the bactericidal activity of tego 103s was compared with that of chlorhexidine in ethanol, and tego 103g with halamid. the activity was determined on pseudomonas aeruginosa, staphylococcus aureus and achromobacter anitratus by various methods. tego 103s in 1% solution was less active than chlorhexidine 0.5% in 70% ethanol, and tego 103g in 1% solution was less active than halamid 0.3%. the presence of serum did not noticeably influence the activity of the tego preparations. | 1970 | 4989853 |

| circular dichroism comparative studies of two bacterial collagenases and thermolysin. | the recently isolated and purified collagenase produced by achromobacter iophagus, the collagenase from clostridium histolyticum, and thermolysin, three enzymes having common properties, were studied by circular dichroism. from the spectra of the aqueous solutions obtained in the peptide region, the fraction of alpha helix, beta sheet and aperiodic segments in the three proteins could be estimated. good similarity was found between achromobacter collagenase and thermolysin, which both contain a ... | 1980 | 6250633 |
| chemical modifications of achromobacter collagenase and their influence on the enzymic activity. | a study of the influence of chemical modifications on the activity of achromobacter iophagus collagenase (ec 3.4.24.8) has led to the following conclusions: a modification of 4 out of 80 cooh groups with carbodiimide led to 90% loss of enzymic activity. a 70% inactivation was found after modification of two tyrosines out of 30 with tetranitromethane. the modification of four to six tryptophans out of 16 with 2-hydroxy-5-nitrobenzyl bromide decreased enzyme activity to 36%. this inactivation is a ... | 1980 | 6251892 |
| chemical characterization of the homogeneous collagenase from clostridium histolyticum. | pure collagenase (clostridiopeptidase a, ec 3.4.24.3) having a molecular weight of 70 000 was obtained from the culture medium of clostridium histolyticym by a combination of ultrafiltrations, molecular sieve, affinity and hydrophobic chromatography. the value of its specific activity is the highest of those described previously but 6-times lower than that of the collagenase from achromobacter iophagus (ec 3.4.24.8). its amino acid composition differs from previous data, namely by the presence o ... | 1981 | 6266487 |
| [study of the spermatic bacterial flora in infertile males (author's transl)]. | two groups of infertile males (65 and 132 patients) have been investigated in two different laboratories, with two different methods to obtain semen. the bacteriological results are quite similar in the two groups. the microorganisms which have been isolated are : beta-hemolytic streptococcus, proteus, epidermidis staphylococcus, micrococcus, corynebacter, viridans streptococcus, klebsiella, pseudomonas, enterobacter, bacillus, neisseria, escherichia coli, anaerobic staphylococcus, anaerobic str ... | 1982 | 6285492 |
| mapping of the plasmid (plq3) from achromobacter and cloning of its cephalosporinase gene in escherichia coli. | we have constructed a physical map of the plasmid plq3 which was originally isolated from achromobacter and which codes for a beta-lactamase. the enzyme specified by plq3 is expressed in escherichia coli and is unusual in that it is a cephalosporinase, an enzyme usually coded for by chromosome. plasmid plq3 is 12.4 kb in length and has a unique bam hi site and two bglii sites. from a bamhi + bglii double digest of plq3, we have constructed a "shortened" plasmid, plq10, in which a 2.96-kb fragmen ... | 1982 | 6286419 |
| solubilization and characterization of chondrosia reniformis sponge collagen. | chondrosia reniformis sponge collagen, insoluble in its native form, was solubilized by chemical modification of lysyl residues. the solubilized sponge collagen had the same amino acid composition as insoluble collagen and the helicoidal tertiary structure was found by negative cotton effect to be the same as in native vertebrate collagens. achromobacter iophagus collagenase, a collagen specific protease, hydrolyzed the soluble sponge collagen. these experiments confirmed that the protein had th ... | 1983 | 6309474 |
| [comparison of sensitivity patterns of bacteria isolated from clinical materials to the 2d generation cephamycins and cephalosporins and clinical application of these antibiotics]. | in vitro susceptibilities of 1478 strains of various pathogens isolated from clinical materials in 1981 to 23 antibiotics were studied using showa disk diffusion test. prevalence of bacterial resistance to antibiotics was evaluated. new cephem antibiotics such as cefmetazole (cmz), cefoxitin (cfx) and cefotiam (ctm) had no increased activity over old cephalosporins such as cephalothin (cet) and cefazolin (cez) against gram-positive cocci. however, all the new ones showed greater activities, broa ... | 1983 | 6317908 |
| effect of different collagenases on the isolation of viable hepatocytes from rat liver. | the isolation of viable hepatocytes from rat liver was found to depend on the source of collagenase (ec 3.4.24.3) more than any other single factor examined. collagenase purified from achromobacter iophagus/bacillus polymyxa (collagenase/dispase) gave reproducibly high viability without the use of complex perfusion protocols. | 1984 | 6329035 |
| bacteremia caused by achromobacter species in an immunocompromised host. | a case of bacteremia caused by achromobacter species in an immunocompromised patient is described. the patient responded to antibiotic therapy. detailed antibiotic susceptibility data are presented. | 1984 | 6332118 |
| cultivation of the bacterial strain achromobacter delicatulus, producing an exocellular polyglucan-type polysaccharide in the fermentation tank fu-6. | growth processes and biosynthesis of the exocellular polyglucan-type polysaccharide, produced by the bacteria achromobacter delicatulus, were studied in the laboratory fermentation apparatus fu-6 under three completely different aeration systems. the purpose of this study was to find the most economical way of the polysaccharide biosynthesis. the growth rate and the synthesis of the exopolysaccharide were not limited either by the oxygen transfer or glucose content under the conditions examined. ... | 1983 | 6359769 |
| in situ identification of bacterial species in marine microfouling films by using an immunofluorescence technique. | an immunofluorescence technique was developed for the in situ identification of specific bacteria in marine microfouling films. microorganisms adherent to glass plates after 30 days of immersion in a synthetic seawater system were cultured and classified by biochemical tests, flagellar arrangement, and the api 20e system. all isolates were gram-negative aerobic or facultative motile rods, predominantly pseudomonas spp. rabbit antisera to the five dominant organisms including achromobacter spp., ... | 1984 | 6393875 |
