摘要: Johnston, M. A. (Cornell University, Ithaca, N.Y.), and E. Delwiche. Distribution characteristics of the catalases Lactobacillaceae. J. Bacteriol. 90:347-351. 1965.-Certain strains lactobacilli pediococci incorporated hematin during growth, with concomitant formation cyanide- azide-sensitive catalase. Three five 25 were capable this biosynthesis. The required heme component blood, whereas could incorporate in form purified solubilized hemin or from blood. In all cases where inhibitor-sensitive enzyme was produced, it accompanied by production inhibitor-insensitive enzyme. absence hematin, only insensitive obtained. Two catalase-positive Streptococcus faecalis found incapable synthesis a heme-type enzyme, as one member genus Leuconostoc. Iron manganese growth medium stimulated catalase, but significant quantities these metals not be preparation obtained Lactobacillus plantarum. Aeration had little no effect on consistently doubled amount azide-resistant By means conventional fractionation techniques, possible to separate two different enzymes present cell-free extract strain Pediococcus homari which been grown presence
