Abstract

Abstract

Breeding of a high lipase- producing strain was studied. The original strain H3 was treated by UV mutation, microwave mutation and compound mutation of 40 s UV and 80 s microwave, the optimum effect was determined by comparing with the enzyme activity.The result showed that the enzyme activity of the strain treated by UV mutation and microwave was 57.984 U / m L and 57.1 U / m L. The enzyme activity was improved 38.3% and36.2% than H3. The enzyme activity of the stain treated by compound mutation was 61.6 U / m L, it was improved46.85% than H3.
