Screening of Bacillus Natto for high efficient degradation of crude protein in corn gluten meal
Bacillus natto was mutagenized with ultraviolet, the plus -mutant NP -4 -170 was obtained by screening with transparent zone method and shaking culture method. Compared with the original strain, the ability of degradation of crude protein in corn gluten meal of the mutant NP-4-170 increased by 2.66%.
