Physiological role of pyruvate oxidase in the aerobic metabolism of Lactobacillus plantarum

Abstract

Under aerobic growth conditions Lactobacillus plantarum produced acetic acid in addition to lactic acid. It was found that lactic acid was predominantly produced at first, and then when the carbohydrate was nearly exhausted, lactic acid was metabolized further to acetic acid. The most likely enzyme involved in the aerobic metabolism of L. plantarum is pyruvate oxidase. Its activity is enhanced in the presence of oxygen and is reduced in the presence of glucose. The specific activity of pyruvate oxidase is highest at the beginning of the stationary-growth phase, where a strong increase in acetic acid production was also observed.
