A strain of high-yield sophorolipid of megachile meadowensis candidum and its application
By screening and domesticating *Candida baccata* LSRH-007 and *Saccharomyces cerevisiae* in soy sauce residue oil culture medium, the problem of yeast strains being prone to death in waste oil was solved, achieving efficient production of acidic and lactone-type sophorolipids and reducing production costs.

Abstract
The application belongs to the field of microbial fermentation, and discloses a high-yield sophorolipid Candida bombicola and application thereof. The Candida bombicola is named as Candida bombicola LSRH-007, and is preserved in China Center for Type Culture Collection, with a preservation number of CCTCC NO: M 20251461. The independently isolated Candida bombicola is combined with Wickerhamiella domercqiae to be used together, so that soy sauce residue oil can replace part of plant oil and the like as a culture medium component to perform fermentation, and a green surfactant sophorolipid is obtained. The fermentation mode can not only promote utilization of waste resources such as soy sauce residue, but also greatly reduce the production cost of sophorolipid, and promote application of the sophorolipid in various fields.
