Screening of A Producing γ-linolenic Acid Mutant Strain(Mortierella isabellina) by UV and LiCl

Abstract

Abstract: A mutant strain SHFU-13 was successfully obtained when the original strain Mortierella isabellina AS3.3410 was treated by UV and LiCl as mutating agent. The biomass was up to 21.66g/L, which was 8.84% higher than that of the original strain while the product of the total lipid was up to 12.65g/L, which was 36.61% higher than that in the original strain mycelium. Analysis by gas chromatograph indicated the content of GLA in the lipid was 6.39% while the product of it was up to 0.81g/L, which was 44.64% higher than that of the original strain. After passing on many times, there were no distinct changes on the production.
