Hemoglobin Improves Sophorolipid Production in O-13-1 Under Oxygen Limited Conditions.

Sophorolipids (SLs) are homologous microbial secondary metabolites produced by and have been widely applied in many industrial fields. The biosynthesis of SLs is a highly aerobic process and is often limited by low dissolved oxygen (DO) levels. In this study, the hemoglobin (VHb) gene was transformed into O-13-1 by homologous recombination to alleviate oxygen limitation.
