Abstract: Disclosed are fermented soybean protein products with enhanced enzyme productivity and methods for producing them by solid fermentation using Bacillus subtilis GR-101 and additionally Aspergillus oryzae GB-107 (KCTC 10258BP). A novel Bacillus subtilis GR-101 strain (KCCM 10673P), which has excellent protease productivity in soybean meal, is also disclosed. Fermentation using Bacillus subtilis GR-101 strain (KCCM 10673P) producing protease combined with Aspergillus oryzae GB-107 (KCTC 10258BP) having amylase activity can remove trypsin inhibitors known as anti-nutritional factors and thus can provide soybean peptides with high digestion ratio and excellent enzyme activities. Feed comprising the soybean peptides as active component and capable of improving productivity of livestock and food for human comprising the soybean peptides supply is further disclosed.
