摘要
A commercial preparation of a lipase produced by Candida cylindracea catalysed the hydrolysis of both long- and short-chain esters of p-nitrophenol. Six major bands of hydrolytic activity to α-naphthyl acetate were detected on polyacrylamide gel electrophoresis and two on isoelectric focusing. The esterase activity fractionated into two major peaks of activity on ion-exchange chromatography and into several peaks of activity on hydrophobic interaction chromatography. These esterase activities showed different substrate specificities to p-nitrophenyl esters, tributyrin and cetyl palmitate. © 1990.
