AEROBIC DISSIMILATION OF GLUCOSE BY HETEROLACTIC BACTERIA

III. ALDEHYDE DEHYDROGENASE AND ALCOHOL DEHYDROGENASE OF LEUCONOSTOC MESENTEROLDES

Abstract

Properties of COA-dependent aldehyde dehydrogenase and NAD-linked alcohol dehydrogenase of Leuconostoc mesenteroides IFO 3426 were studied, and it was found that the two dehydrogenases cannot be separated from each other, as well as from those of Escherichia coli B, by various methods of enzyme fractionation. It was also observed that the dehydrogenases of Leuconostoc mesenteroides appeared in a precipitate fraction prepared by centrifugation at 105, 000×g, and estimated to be associated with intracellular particles containing RNA.
