摘  要:
BP neural network and genetic algorithms methods were used to optimize the fermentation medium of Bacillus thuringiensis. The best fermentation medium is 0.392 8% yeast extract, 0.492 8% corn meal, 2% defatted peanut flour, 0.035% MgSO4 · 7H2O, 0.025%KH2PO4, 0.049 6% CaCO3. The spore production was 6.3×108/mL under this condition,which was 7.7% higher than that by RSM method.
