摘要:
Transesterification between ethyl butyrate and glycerol using very different lipase preparations (native, modified, and immobilized) in a two-phase system-no extra solvent added-has been investigated. Optimal conversion was obtained with the presence of 5% water in the reaction mixture. Only monobutyrin was produced in all conditions tested. The best enzyme preparations were native Candida cylindracea lipase, Mucor miehei lipase immobilized on a phenol-formaldehyde exchange resin (Lipozyme™), and C. cylindracea lipase immobilized on Celite. © 1990 Humana Press Inc.
