To increase the yield of acetic acid production, the author developed the bacterial strain which could brow well in high concentration of ehtanol from the seed culture using in conventional vinegar production factory. By attenuation of the isolated strain in the broth media containing 5-10% ethanol, we could get the strain which could grow in the broth medium containing 10% ethanol. This strain was identified and named as Acetobacter sp. FM-10, and it's cultural characteristics were also investigated. The medium containing 10% ethanol, 5% glucose and 1% yest extract was suitable for the acetic acid production with Acetobacter sp. FM-10. Optimum temperature and pH for the growth of Acetobacter sp. FM-10. were $30^{\circ}C$ and 5.0, respectively. The acidity of culture medium was reached to 9.0 % after 20 days static cultivation at $30^{\circ}C$.
