Effects of propionate on the growth of Rhodopseudomonas spheroides S were examined in the presence of various carbon compounds. Propionate strongly inhibits the growth on the medium containing glucose as a carbon source under aerobic-dark conditions, but not under anaerobic-light conditions. This inhibition can be restored by the addition of acetate or NaHCO3 to the culture medium. Pyruvate, acetoin and acetaldehyde are accumulated in the culture medium during the growth inhibition induced by the addition of propionate. Metabolic pathway in the bacterium is discussed.
