摘要：

We have purified and characterized two isoenzymes from a commercial lipase preparation of Candida cylindracea. The purification procedure includes ethanol precipitation and DEAE Sephacel and Sephacryl HR 100 chromatographies. Lipase A and lipase B were purified 11-fold with a 5% and 21% recovery in activity, respectively. The enzymes have similar amino acid content, N-terminal sequence and molecular weight, but differ on neutral sugar content, hydrophobicity, presence of isoforms and stability to pH and temperature. They also show some differences in the substrate specificity.
