nonoxidative pentose phosphate pathway in veillonella alcalescens.crude cell-free extracts of veillonella alcalescens c1, an anaerobe unable to ferment glucose, were assayed for individual enzymes of the pentose phosphate pathway. glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase activities were not detectable. constituent enzymes of the nonoxidative limb of the pentose phosphate pathway were demonstrable. the presence of transaldolase, transketolase, phosphoribose isomerase, and phosphoribulose epimerase in this organism suggests a primar ...19704904232

multiple impairment of glycolysis in veillonella alcalescens.the property of glucose nonfermentation, characteristic of the genus veillonella, was investigated in v. alcalescens c1, a strain of sheep rumen origin. cell-free extracts as well as intact cells were incapable of glucose fermentation, thereby eliminating the possibility of nonpermeation. assimilation of (14)c-glucose was not detectable. of the 10 glycolytic enzymes, hexokinase, phosphoglyceromutase, and pyruvate kinase were not detectable. the other glycolytic enzymes were present.19705460841

regulatory properties of acetokinase from veillonella alcalescens.acetokinase from veillonella alcalescens catalyzes the virtually irreversible synthesis of adenosine triphosphate from acetyl phosphate and adenosine diphosphate. kinetic analysis revealed that the enzyme was activated by acetyl phosphate and inhibited by adenosine triphosphate. velocity curves obtained with increasing amounts of adenosine diphosphate were of the michaelis-menten type (rectangular hyperbolas) under all conditions employed. however, velocity curves generated by varying the level ...19715541011

lactate metabolism by veillonella parvula.a strain of veillonella parvula m4, which grows readily in lactate broth without a requirement for carbon dioxide, has been isolated from the oral cavity. anaerobic, washed cells of this organism fermented sodium lactate to the following products (moles/100 moles of lactate): propionate, 66; acetate, 40; carbon dioxide, 40; and hydrogen, 14. cells grew readily in tryptone-yeast extract broth with pyruvate, oxaloacetate, malate, and fumarate, but poorly with succinate. the fermentation of pyruvat ...19714323300

an enzyme-based theory of obligate anaerobiosis: the physiological function of superoxide dismutase.the distribution of catalase and superoxide dismutase has been examined in various micro-organisms. strict anaerobes exhibited no superoxide dismutase and, generally, no catalase activity. all aerobic organisms containing cytochrome systems were found to contain both superoxide dismutase and catalase. aerotolerant anaerobes, which survive exposure to air and metabolize oxygen to a limited extent but do not contain cytochrome systems, were found to be devoid of catalase activity but did exhibit s ...19714995818

ability of veillonella and neisseria species to attach to oral surfaces and their proportions present indigenously.the present study describes the distribution of veillonella and neisseria species in the human oral cavity and indicates that their ability to attach to oral surfaces correlates with their proportions found in various sites of the mouth. the mean percentages of veillonella and neisseria of the total flora cultivable on anaerobic blood-agar plates was found to be: plaque, 0.75 and <0.13, respectively; lip, 0.38 and <0.05; cheek, 0.66 and <0.14; tongue dorsum, 9.4 and <0.12; saliva, 5.0 and <0.9. ...19715154885

an alternate complement pathway: c-3 cleaving activity, not due to c4,2a, on endotoxic lipopolysaccharide after treatment with guinea pig serum; relation to properdin.the reaction between endotoxic lipopolysaccharide (lps) and the guinea pig complement system was shown to proceed by way of an intermediate complex, lps-x, which contains at least six guinea pig serum proteins. lps-x, like [unk] (sheep erythrocytes carrying antibody molecules and [unk] complexes), destroys the c3 molecule by cleavage. on incubation at 37 degrees c, lps-x loses its capacity to destroy c3 at about the same rate as the decay of [unk], so that it has been assumed that lps-x carries ...19715288385

in vitro evaluation of actinobolin as an antibiotic for the treatment of periodontal disease.actinobolin was evaluated in vitro by a paper disc-agar diffusion method for inhibitory activity against mixed microbial cultures obtained from patients with periodontal disease and against pure bacterial cultures tentatively identified as strains of bacteroides melaninogenicus, fusobacterium fusiforme, leptotrichia buccalis, and veillonella parvula. every culture tested was inhibited to some degree by actinobolin. these observations suggest that actinobolin may be effective in the treatment of ...19725059624

ribose utilization by veillonella alcalescens.the utilization of ribose by veillonella alcalescens has been further investigated. nonfermentation of ribose is not a result of a phosphorylation lesion since ribose-phosphorylating activity was measured in cell extracts. resting cells accumulated ribose-5-phosphate and nucleotides when (14)c-ribose was provided; no other sugar phosphates were detectable. resting cells that were shifted to growth conditions polymerized rather than degraded the accumulated ribose compounds. cell extracts contain ...19724334763

kinetic properties of phosphotransacetylase from veillonella alcalescens.the phosphotransacetylase of veillonella alcalescens catalyzes a reversible reaction with michaelis-menten kinetics for all substrates. the rate of the reverse reaction (the synthesis of acetyl coenzyme a from acetyl phosphate) was 6.5 times greater than the rate of the forward reaction (the synthesis of acetyl phosphate from acetyl coenzyme a). the apparent k(m) values determined for the forward reaction were 8.6 x 10(-6)m for acetyl coenzyme a and 9.3 x 10(-3)m for phosphate. in the reverse re ...19724360222

comparison of methods for isolation of anaerobic bacteria from clinical specimens.five different anaerobic culture methods and several different media were compared for their ability to recover anaerobes from clinical specimens. specimens were obtained from patients with documented infections, avoiding contamination with normal flora, and immediately placed in an anaerobic transporter. each specimen was cultured by all methods and on all the various media. the comparative data indicate that anaerobic jars (gaspak and evacuation-replacement types) are just as effective in the ...19734568893

the effect of perfusion on the flora of the excluded colon.the bacterial flora of excluded colonic segments of three patients has been examined in the normal resting state and following perfusion.the flora of the excluded colon was substantial and qualitatively similar to that of faeces. perfusion for two hours at 10 ml per minute usually reduced counts of organisms present in the issuing effluent by 1 to 1(1/2) logs in two patients, but rises in the counts of some organisms were recorded from the third patient. prolonged rapid perfusion or the inclusio ...19734573344

the effect of a chemically defined diet on the faecal flora and faecal steroid concentration.the consumption of a chemically defined diet altered both the faecal flora and faecal steroids. enterobacteria increased while enterococci and other lactic acid bacteria decreased in number. no other obvious change occurred. however, the alteration in the degree of degradation of the faecal neutral steroids may reflect some alteration in the anaerobic flora. total excretion of both acid and neutral steroids was also reduced. on cessation of the diet both faecal flora and faecal steroids reverted ...19734202272

nitrate reduction and the growth of veillonella alcalescens.veillonella alcalescens, a strict anaerobe, was found to possess a nitrate reductase system which has characteristics of both assimilatory and respiratory nitrate reduction. the nitrate reductase has been identified tentatively as a particulate enzyme which utilizes a variety of electron donors for the reduction of nitrate. by use of (15)n-labeled nitrate, it was shown that under appropriate conditions nitrate nitrogen is incorporated into cell material. v. alcalescens grown on pyruvate and nitr ...19734145863

the effect of vagotomy and drainage on the small bowel flora.the incidence of small intestinal colonization in unoperated duodenal ulcer patients was low and similar to that in the normal population. the majority of patients seven to 10 days following truncal vagotomy and drainage were colonized whereas none of a control group of patients following simple closure of a perforated duodenal ulcer was colonized. in patients with pyloroplasty, this high incidence fell to control levels on average 18 months postoperatively, but in patients with a gastro-jejunos ...19744820640
