| Popis: |
Ribitol dehydrogenase from Aerobacter aerogenes strain 1033 acted only on ribitol, but was induced both by ribitol and by d -arabitol. The induction of this enzyme by d -arabitol was shown to depend on its metabolism. A mutant which produced ribitol dehydrogenase constitutively was isolated, in which the formation of this enzyme was apparently no longer regulated by the inducer, although catabolite repression continued to exert its influence. Ribitol dehydrogenase was obligatory for the utilization of ribitol under both aerobic and anaerobic conditions. Under anaerobic conditions the growth rate on ribitol was severely limited by inadequate hydrogen acceptors and was stimulated by the addition of fumarate to the growth medium. |
