ABSTRACT
To obtain oleaginous yeast mutants with improved lipid production and growth rates, an atmospheric and room temperature plasma (ARTP) jet was used with a 96-well plate for high throughput screening. Mutants with changes in growth rates and lipid contents were obtained. At a lethality rate of 99%, the positive mutation rate of the yeast cells was 27.2% evaluated by the growth rates of the mutants and the comparison with the wild strain. The fermentation in a medium composed of yeast extract (10 g/L), peptone (10 g/L) and D-glucose (20 g/L) resulted in the lipid yield of the mutant (C4) with 4.07% (W/W) compared with that of the wild strain (1.87%).
