Major Products of Glucose Dissimilation by Pseudomonas natriegens

Abstract

Eagon , R. G. (University of Georgia, Athens), and H. W. Cho . Major products of glucose dissimilation by Pseudomonas natriegens . J. Bacteriol. 89: 1209–1211. 1965.— Pseudomonas natriegens aerobically catabolized glucose to yield predominantly acetic acid, pyruvic acid, and CO 2 , whereas little or no lactic acid was formed. Under anaerobic conditions, glucose in an enriched medium was fermented to yield acetic acid and lactic acid but no pyruvic acid or CO 2 . Glucose in a basal salts medium was fermented to yield predominantly acetic acid, lactic acid, and CO 2 , while small amounts of pyruvic acid were detected. It was suggested that the aerobic accumulation of acidic products results from rapid glucose dissimilation to the oxidation level of pyruvic acid, followed by a less rapidly functioning tricarboxylic acid cycle.
