Presence of an L(+)-lactate dehydrogenase in cells of Lactobacillus delbrueckii ssp. bulgaricus.
Lactobacillus delbrueckii ssp. bulgaricus ATCC 11842 was cultured in a chemostat and growth conditions were varied as required. Synthesis of L(+)-lactate was observed in all cases as well as activity of L(+)-lactate dehydrogenase in cell-free extracts. This enzyme was responsible for the formation of the L(+) isomer of lactate, since a lactate racemase was not present.
