Abstract
SUMMARY: Suspensions of Bacillus subtilis form DL-alanine when incubated with pyruvate and ammonia. When leucine and valine are formed from the analogous keto acids, only the L-isomer is found. Since B. subtilis has a racemase active for alanine but not for valine or leucine, it is possible that the L-alanine may be the primary product and which is then racemized.Keywords
