Breeding of a strain of oleaginous yeast via the microwave mutation

The mutant strain Y13 was isolated by the time of optimum microwave mutagenesis,mutagenic strains of screening and re-screening within oleaginous yeast Y1.The results showed that Y13 was significantly improved in oil production and content,the oil production reached 4.39 g/L from 2.11 g/L and the content reached 22.09% from 9.6%,respectively.It is feasible to employ Y13 as original strains using shake-flask fermentation for lipid-producing.
