1. It is presumed that glucose is metabolized by a AsA-degrading bacterium through Embden and Meyerhof's pathway anaerobically and through Warburg and Dickens' pathway aerobically.
2. The metabolic products of araboacorbic and D-gluconic acid and D-ribose were proved to be lactic, acetic and formic acid by paper chromatography.
3. D-Ribose was found to be a metabolic product of dehydroascorbic acid.
4. The lactic acid, which was found on the way of the degradation of ascorbic acid or other substrates, was proved to be a D-form.
5. The total pathway of ascorbic acid degradation was clarified.
