Organic Acid Metabolism by Isolated Rhizobium japonicum Bacteroids.

Rhizobium japonicum bacteroids isolated from soybean (Glycine max L.) nodules oxidized (14)C-labeled succinate, pyruvate, and acetate in a manner consistent with operation of the tricarboxylic acid cycle and a partial glyoxylate cycle. Substrate carbon was incorporated into all major cellular components (cell wall + membrane, nucleic acids, and protein).
