Assimilation of organic acid by acetic acid bacteria was investigated.
Of lowerfatty acids, formic, propionic, butyric and valeric acids and oxalic and glutaric acids of dibasic acid were not assimilated by all type cultures examined.
Of dibasic acid, molonic, succinic and fumaric acids, lactic, malic, tartaric and citric acids of hydroxy carboxylic acid were assimilated by the strains oxidizing strongly ethyl alcohol to acetic acid.
Salts of the organic acids were assimilated by the strains in the same degree as free acids.
Assimilation of free organic acids by the isolated strains were nearly similar to that of the type cultures.
