Exogenous l-proline improved Rhodosporidium toruloides lipid production on crude glycerol

Abstract

Our study suggested that exogenous l-proline improved cell growth and lipid production on crude glycerol by <i>R. toruloides</i>. The fact that higher lipid yield as well as glycerol consumption indicated that l-proline might act as a potential anti-stress agent for the oleaginous yeast strain.
