Abstract
1. Phototrophic cultures of Rhodomicrobium vanielii do not excrete glycollate when gassed anaerobically with nitrogen plus carbon dioxide, although the addition of alpha-hydroxy-2-pyridine methanesulphonate (HPMS) results in the excretion of a trace amount of glycollate. The inclucion of low amounts of oxygen in this gas mixture results in marked glycollate excretion, higher rates occurring in the presence of HPMS. 2. Cell extracts of Rhodomicrobium vannielii, and also of Rhodospirillum rubrum, which excretes glycollate only under aerobic conditions in the light, catalyze the formation of glycollate from phosphoglycollate and also the oxidation of glycollate to glyoxylate.
