Abstract

Nocardia tartaricans converted sodium cis-epoxysuccinate to L-tartrate. The highest cis-epoxysuccinate hydrolase activity (37.7 U mg−1) was obtained with 0.02% (w/v) sodium deoxycholate, but this inactivated the cells. Immobilized N. tartaricans in pectate gel showed higher enzyme activity (51 U mg −1) compare to the free cells (8.9 U mg −1). After 450 days, the immobilized cells still possessed 0.65 U mg −1, i.e. 30% of the initial enzyme activity.
