One of bacteria on the surface of a soybean was isolated and identified as Bacillus subtilis. The bacterium was named Bacillus subtilis MF920. We studied effect of natural materials to its growth. Growth inhibition by glycine has been known. However, when bacteria were heated with some amino acids, L-serine sterilized more bacteria than glycine. Amino acid analysis clarified that heating did not cause the decomposition of L-serine. This indicated that L-serine itself caused the growth inhibition.
