ABSTRACT:
A process is described for stereospecifically hydrating crotonobetaine to L-(-)-carnitine via the action of an enzyme produced by four new strains of Proteus mirabilis (NRRL B-18480, NRRL B-18481, NRRL B-18482, and NRRL B-18483) in biotransformation media containing from 10 to 12% (w/v) crotonobetaine inner salt.
