| Abstract: | Solid fermentation and drying process of Bacillus subtilis strain Bs2004 were studied.The results showed the best fermentation substrate was the wheat bran and soybean meal mix equal.The maximum bacteria reached to 9.62×109 cfu/g when moisture content was 65%,5% sucrose and 5% yeast extract were included in water,pH value was 7.5 and it was fermented at 32 ℃ for 24 h.The viable bacteria reached to 9.581×109 cfu/g when fermentation was dried in 65 ℃ and vacuum,it was recommended as the best drying method. |
