19 strains of infectious bacteria in the alcoholic fermentation were isolated from the alcohol-mashes peroduced by the amylo-shubo and submerged fungal method and by the open fermenter system. By the use of penicillin, streptomycin, fradiomycin, bacitracin, polymyxin, aureomycin, ferromycin (H-43 substance) and azomycin, their minimum inhibitory concentrations against the growth of isolated bacteria were determined. Penicilllin, aureomycin, ferromycin and pllymyxin indicated good activities against these infectious bacteria in concentrations of 1〜5 μg per ml.Of the 19 strains, No. B-14 strain was found to produce an antiyeast substance.In the fermentation tests on a small scale, the addition of penicillin, aureomycin, polymyxin and ferromycin to a mash which was inoculated in advance with B-14 strain and soil suspension could prevent the decrease in the yield of ethyl alcohol.
