Strain Improvement of Lipomyces starkeyi ATCC 12659 via Random Mutagenesis for Optimized Lipid Production

This study was performed to conduct genetic improvement of the oleaginous yeast Lipomyces starkeyi for the enhancement of lipid production. Strain improvement was carried out via random mutagenesis by using ethidium bromide treatment and mutant selection by using cerulenin. Ten mutant isolates demon...
