Abstract
A general review of the acetic acid bacteria belonging to the intermediate type was accomplished physiologically, biochemically and morphologically. Conclusively, it was clarified that these were clearly a specific group and different from both Acetobacter and Gluconobacter. These were intermediate between lactaphilic and glycophilic, besides, on the carbohydrate oxidizability, these were intermediate between Acetobacter and Gluconobacter as mentioned previously.1) These showed the same result as Acetobacter on the vitamin requirement for the growth, but were closely related to Gluconobacter on the carbohydrate availability. And on the oxidative activity for amino acid, accompanying the deamination, these were also clearly distinguished from both Acetobacter and Gluconobacter, particularly these oxidized strongly L-serine. Differing from the observations by other investigators, these showed single flagellation, with the exception of multi-polar, but never multi-peritrichous.
