摘要：

A membrane bioreactor was developed for continuous synthesis of glycerides by lipase to overcome the drawbacks associatedwith the usual operation in an emulsion system. One unit (total area: 726 cm2) of flat, plate-type dialyzer was used as the membrane bioreactor at 40 C. The glycerol solution, containing bacterial lipaseand water, was supplied continuously to 1 side of a sheet of microporous polypropylene membrane (strongly hydrophobic) andthe effluent was recycled, while undiluted liquid fatty acid (oleic or linoleic) was fed continuously to the opposite sideof the membrane and came in contact with a glycerol-water-lipase solution to cause the reaction. The product, glycerides,was obtained at the outlet, in a pure state, with no other phase. Highest conversion (ca. 90%) was obtained when the watercontent of the glycerol solution was 3–4%. As the accumulation of water produced by the reaction lowered the conversio
