| Abstract: | A bacterium producing alkaline lipase was re-screened from five strains. The alkaline lipase activity was the highest in strain F12 and studies revealed that this strain is Bacillus coagulants. The optimal conditions of the bacterium strain producing alkaline lipase is (%): soy bean cake flour 2.5, corn steep liquor 1.5, soluble starch 0.5, K2HPO4 0.5, NaNO3 0.5, initial pH9.0, culture temperature 28℃～30℃ for 22～26 hour. |
