The change of organic acids and the evolution of carbon dioxide during fermentation by the strain No. S-8 were investigated.1. Twelve kinds of organic acids were detected by the partition chromatography, and the sum of formic and acetic acids was about 75 per cent of total acid.2. The proportion of organic acids produced was almost constant during fermentation, and the ratio of acetic acid, formic acid and carbon dioxide was 1 : 2 : 1.On the basis of the observed change of formic acid and absence of hydrogen gas, it was presumed that carbon dioxide was not originated from formic acid.3. The amounts of total acids, carbon dioxide evolved and the proportion of acids produced were not affected by the presence of indigo.The direct relationship between the formation of acids and the reduction of indigo was not recognized.
