摘要： The present invention relates to a process for producing esters comprising reaction of methyl biodiesel or free fatty acids with a polyhydroxylated alcohol, in the presence of a biocatalyst, which is a fermented solid containing lipases of Rhizomucor miehei produced by culturing the microorganism on agricultural waste by solid state fermentation.
