Abstract
As important chemical raw materials and potential nutritional supplements, microbial lipids play an important role in ensuring economic development, food security, and energy security. Compared with non-natural hosts, oleaginous yeasts exhibit obvious advantages in lipid yield and productivity and have great potential to be genetically engineered into an oil cell factory. The main bottleneck in the current oleaginous yeasts engineering is the lack of genetic manipulation tools. Fortunately, the rapid development of synthetic biology has provided numerous new approaches, resources, and ideas for the field. Most importantly, gene editing technology mediated by CRISPR/Cas systems has been successfully applied to some oleaginous yeasts, almost completely rewriting the development pattern of genetic manipulation technology applicable. This paper reviews recent progress in genetic technology with regard to oleaginous yeasts, with a special focus on transformation methods and genome editing tools, discussing the effects of some important genetic parts. KEY POINTS: •Contribution of microbiotechnology in food safety and biofuel by oleaginous yeasts. •Advancement of genetic manipulation and transformation for oleaginous yeasts.
