Abstract
A method is described which utilizes lipases to transesterify triglyceride-containing substances and to esterify free fatty acids to alkyl esters using short chain alcohols. The alkyl esters are useful as alternatives or additives to automotive fuels and lubricants. The method is particularly advantageous because it utilizes inexpensive feedstocks such as animal fats, vegetable oils, rendered fats and restaurant grease as substrates.
