Abstract:  60 samples were selected from oil dregs of oil refining plant, screened by plate and liquate medium and menstruated lipase activity, starting strain was obtained by compared diameters of colony and hydrolyzed transparency circle on screening plate. The strain were obtained by mutagenesis with UV, which has high and special hydrolyze to perilla oil with rich a-linolenic acid and its lipase activity was 52.3% higher than that original strain.

Key words: &alpha, -linolenic acid; special lipase; mutagenesis; lipase activity
