influence of water activity on the growth of clostridium perfringens.each of four strains of clostridium perfringens was grown in modified fluid thioglycolate medium which was adjusted to yield selected water activity (a(w)) levels. the adjustments to secure the desired a(w) levels were made with nacl, kcl, or glucose. at each a(w) level, further modification was effected to produce four ph values. cultures were incubated at either 37 or 46 c. the solute used to achieve the reduced a(w) levels appeared to have a definite effect on the magnitude of growth achieved ...19704318452

action of bacterial growth on the sarcoplasmic and urea-soluble proteins from muscle. i. effects of clostridium perfringens, salmonella enteritidis, achromobacter liquefaciens, streptococcus faecalis, and kurthia zopfi.comparisons of the starch-gel patterns of uninoculated aseptic control samples from rabbit and pig muscle with similar samples inoculated and incubated with clostridium perfringens, salmonella enteritidis, achromobacter liquefaciens, and kurthia zopfii were made. results indicated that c. perfringens caused extensive alteration in the proteins or enzymes, or both, of the sarcoplasmic fraction of porcine muscle, whereas s. enteritidis and s. faecalis caused complete breakdown of only myoglobin. n ...19704318570
characterization of clostridia by gas chromatography differentiation of species by trimethylsilyl derivatives of whole-cell hydrolysates.trimethylsilyl (tms) derivatives prepared from whole-cell hydrolysates of 36 strains, representing 10 species of clostridium were examined by gas-liquid chromatography (glc). the tms profile of each species contained a group of peaks which characterized the species. variation among strains within a species was much lower than variation between species. some of the closely related clostridia could be differentiated by comparing their tms profiles. strains of clostridium botulinum were distinguish ...19704318575

effect of bile acid deconjugation on the fecal excretion of steroids.the effect of microbiological deconjugation of bile acids on total bile acid and neutral sterol fecal excretion by adult male rats has been studied. a screening method utilizing mice allowed selection of a clostridium perfringens type a strain, which accelerated cholesterol catabolism in mice. when this species of bacteria was associated with germfree rats, the fecal bile acids were excreted as free bile acids (deconjugated), however the quantities of bile acids excreted were not increased compa ...19704318910
