Abstract: One strain of Bacillus natto with high antimicrobial activity was isolated from Natto. The antimicrobial effects on some bacteria, yeasts and moulds were investigated, and were also compared with some food preservatives. Besides, the antimicrobial effect was proved to be hereditaril stable.
