Abstract: In order to explore extra-cellular enzyme secreted by Eurotium cristatum fungi, the enzymatic productivity and activity changes on carboxymethyl cellulase(CMCase), proteinase, amylase, pectinase and lipase were analyzed according to the methods of hydrolyzed circle and liquid cultivation. The results showed that there were obvious hydrolyzed circles appearsed on the plate medium with starch and olive oil, but not on plate medium with sodium carboxymethyl cellulose, pectin and milk. Except lipase, other enzymes were detected and their activities were varied obviously during liquid cultivation.

Key words: Eurotium cristatum, extra-cellular enzyme, activity changes
