    摘要: A finished vinegar having an acetic acid concentration higher than 20 percent weight by volume is produced by repeating a fermentation cycle wherein a broth is fermented at 27.degree.-32.degree. C. in a 1st submerged fermentation tank by a continuous batch process, and, when the acetic acid concentration of the fermenting broth reaches 12-15 percent weight by volume, the large part of the fermenting broth in the 1st fermentation tank is withdrawn and charged in a 2nd submerged fermentation tank. The 1st fermentation tank is recharged with a mash and the fermentation of the fermenting broth in the 2nd tank is continued under aeration while lowering the temperature of the fermenting broth in such manner that the final fermentation temperature does not fall below 18.degree. C. and the lowering temperature does not become higher than the temperature once lowered.

    摘要: Vinegar having an acetic acid concentration higher than 20 percent weight by volume is produced in a submerged fermentation by maintaining the temperature of a fermenting broth at 27.degree.-32.degree. C. until the acetic acid concentration of the fermenting broth (after the initiation of fermentation) reaches 12-15 percent weight by volume. Then the temperature of the fermenting broth is lowered by 0.5.degree. C. to 2.degree. C. Fermentation is continued at the lower temperature until the concentration of acetic acid increases by between 0.05 to 2 percent weight by volume. At this time, the temperature is again reduced by from 0.5.degree. C. to 2.degree. C. The fermentation is continued, with subsequent temperature reductions of from 0.5.degree. C. to 2.degree. C. each time that the concentration of acetic acid in the fermentation broth increases by 0.05 to 2 percent weight by volume over the highest concentration found in the course of the fermentation at the preceeding temperature stage, until the desired concentration of acetic acid is obtained. However, at no time is the temperature of the fermenting broth allowed to fall below 20.degree. C.

    摘要: 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 containing at least 4 w/v % of acetic acid with a pH of 3.5 at the highest. Pure samples of species have been isolated and used for the fermentation production of vinegar without undertaking the conventional inoculation process using the prior art seed vinegar to provide a high-quality vinegar of high acetic acid concentration such as white vinegar, with high production efficiency.
