摘要: A novel expression system was established in the oleaginous yeast, Lipomyces kononenkoae. The expression vector pLK-rhPHG of L. kononenkoae was constructed and using the hygromycin phosphotransferase gene and green fluorescent protein gene as reporter genes. A delta 6-fatty acid desaturase gene (D6DM) from Cunninghamella echinulata MIAN6 was then expressed in this strain. The recombinant strain accumulated about 1.2% gamma-linolenic acid in the total fatty acids.
