Sulfonamide Resistance of Clostridium Sporogenes.
Bacteria which are sulfonamide-sensitive have been reported to be incapable of the rapid utilization of folic acid for inhibition reversal (Alimchandani and Sreenivasan, J. Bacteriol. 73:538, 1957; Krieg and Pelczar, J. Bacteriol. 80:242, 1960; Davis and Feingold, p. 343. In I. C. Gunsalus and R. Y. Stanier [ed.], The Bacteria, vol. 4, Academic Press, Inc., New York, 1962), presumably because o...
متن کاملRegulation of protease production in Clostridium sporogenes.
The physiological and nutritional factors that regulate protease synthesis in Clostridium sporogenes C25 were studied in batch and continuous cultures. Formation of extracellular proteases occurred at the end of active growth and during the stationary phase in batch cultures. Protease production was inversely related to growth rate in glucose-excess and glucose-limited chemostats over the range...
متن کاملElectrosynthesis and electroanalysis using Clostridium sporogenes *
A polarographic approach was developed for studying the biochemical physiology and biotechnological utility of the proteolytic anaerobe Clostridium sporogenes. Methyl viologen-mediated reductions were assessed in both analytical and preparative modes, using a dropping mercury electrode and a mercury pool electrode, respectively. Using these assays, we observed an active MV-linked NAD(P) reducta...
متن کاملRegulation of the arginine dihydrolase pathway in Clostridium sporogenes.
Arginine deiminase activity was induced during the vegetative growth of Clostridium sporogenes. The enzyme was sensitive to catabolite repression. The other enzymes of the arginine dihydrolase pathway, namely, ornithine carbamoyl-transferase and carbamate kinase, did not show such variation.
متن کاملInterconversion of valine and leucine by Clostridium sporogenes.
Clostridium sporogenes has been found to require L-leucine and L-valine for growth in a minimal medium, although valine can be replaced by isobutyrate and leucine by isovalerate. Cells grown in minimal media incorporated significant 14C from [14C]valine into leucine and from [14C]leucine into valine. Growth with [4,5-3H]leucine also resulted in the incorporation of 3H into valine. These results...
