Specific activities of the quinone-dependent D-lactate dehydrogenase Dld in crude extracts of C. glutamicum WT grown in different media. The values represent means and standard deviations of at least three independent cultivations in LB complex medium without or with 100 mM L-lactate or 100 mM D-lactate or in CgXII mineral medium containing either 100 mM glucose, 100 mM L-lactate, 100 mM D-lactate or 100 mM pyruvate as carbon source.
