It is well known that the acetic acid bacteria can rapidly oxidize ethanol to acetic acid. But whether ethanol can serve as a source of carbon and energy for these bacteria has not been clearly established. Pasteur (1868) noted that Mycoderma aceti which is undoubtedly Acetobacter aceti (Frateur, 1950) can grow well in ethanol media only if acetic acid is also present. Addition of one or two pe...

Relatively little information is available on the specific nitrogen and growth factor requirements of the acetic acid bacteria. The early observation of Hoyer (1898) and of Beijerinck (1898) that only Acetobacter aceti can develop in a mineral salts-ammonium nitrogen medium with ethanol plus acetate as the source of carbon has acquired taxonomic and diagnostic value for this and, more recently,...

A novel species of acetic acid bacteria belonging to the genus of Acetobacter, to which a scientific name of Acetobacter altoacetigenes MH-24 (FERM BP-491) is given. The bacteria can grow in a culture medium con taining at least 4 w/v. 9% of acetic acid with a pH of 3.5 at the highest. Pure samples of species have been iso lated and used for the fermentation production of vine gar without under...

UNLABELLED Volatiles are small air-transmittable chemicals with diverse biological activities. In this study, we showed that volatiles produced by the bacterium Bacillus subtilis had a profound effect on biofilm formation of neighboring B. subtilis cells that grew in proximity but were physically separated. We further demonstrated that one such volatile, acetic acid, is particularly potent in s...
