Abstract
The fermentation of bacillus licheniformis LNPU-1 was investigated through single-factor test .The main factors include: temperature, initial pH and rotate speed. The optimal fermentation conditions are: temperature 35℃, initial pH 7.0, 150r/min. The orthogonal experiment was used to optimize the medium, in the optimized condition, the bacterium concentration increased from 5.10×109cfu/mL to 4.93×1010cfu/mL.
