1. A process for producing biolubricant esters, comprising:
a) culturing a microorganism on agricultural waste by solid state fermentation to obtain a biocatalyst; and
b) reacting methyl biodiesel or free fatty acids with a polyhydroxylated alcohol in the presence of the biocatalyst obtained from step a) to generate one or more biolubricant esters,
wherein
the agricultural waste is cottonseed cake or palm oil cake;
the biocatalyst comprises a fermented solid produced by the solid state fermentation of the agricultural waste by the microorganism; and
the methyl biodiesel is soya biodiesel or castor oil biodiesel.
