Abstract

T.viride was used to produce extracellular lactase in different media. Effect of various carbon sources (lactose, glucose, galactose, sucrose, maltose, fructose and xylan) on enzyme production was investigated. Among nitrogen sources, (NH4)H2PO4 was concluded to be the best nitrogen source, followed by (NH4)2HPO4 and (NH4)2SO4. In addition, increasing (NH4)H2PO4 concentration to 0.250 M increased enzyme production. Finally, additional glucose was not effective on lactase production.
