摘要
Abstract
Bacillus sublitis was inoculated in soybean meal substrate, this fermented soybean meal want detected crude protein and hydrolysis of protein. Compared the increase of crude protein and hydrolysis of protein, fer atation conditions including carbon resource, temperature, moisture, culturetime and inocuiant concentration wer optimized by orthogonal design. The result showed that the sequence of effect factor for crude protein increase were corn ration> culture time > temperature >wheat bran ration> moisture > wheat short ration> inoculant concentration, he highest crude protein increase was 28. 05% in culture condition was A2 B1C3 D3 E2 F2 G1. The sequence of effect factor floydrolysis of protein increase were temperature > culture time > cornmeal ration > inoculant concentration > wheat brat ration > wheat short ration > moisture. The highest hydrolysis of protein increase was 46. 46% in culture condition W83B3C1D3E3F3G1. The increase rate of crude protein and hydrolysis of protein counted was positive relevance (R2 =0.556).关键词
