Abstract Silica gel is a useful support for the lipases of Geotrichum candidum. Esterification of selected fatty acids and alcohols proceeded to 85-92% conversion in hydrocarbon solvents, and the degree of esterification was increased to 96-98% by adding 4 angstroms molecular sieves at later stages of reaction. The equilibrium ratio of ester to fatty acid (butyl oleate to oleic) was determined for the supported lipase in a number of solvents and ranged from 92:8 in hexane and isooctane to 16:84 in t-butanol. The essential character of the enzyme seemed unimpaired by deposition onto silica gel as judged by fatty acid selectivity and stereoselectivity.
