Abstract: The acid-producing bacterial strain C52 was isolated from rice grains. It produced acid in high capacity to inhibit the growth of Aspergillus and Penicillium, which were the main pathogens. Results of laboratory tests in 1989 and 1990 indicated that bacterial C52 decreased the mildew of wet grains. When wet grains were treated with C52 bacterial suspension, their rate of mould, spore number per gram of grain and rate of yellow kernel were lower than those of control. Mould control effect of C52 were increased if the bacterial suspension mixed with sterilized ash before tests, as ash could make the bacteria spread better.
