Abstract
A purified acetyl esterase (AE), isolated from a commercial enzyme preparation, released acetic acid from water-soluble and water-insoluble cellulose acetates (CAs), native and chemically acetylated xylan as well as acetylated starch. The AE specifically cleaved off the acetyl substituents from the C2- and C3-positions from CAs of DS <1.8 and left the acetyl substituents at the C6-positions intact without degrading the polysaccharide. The activity of endoglucanase was enhanced by the presence of acetyl esterase, while the acetyl esterase derived no advantage from the presence of the endoglucanase; it was able to function independently.
