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 nitrogensources, NH4 H2PO4 was concluded to be the best nitrogen source, followed by NH4 2HPO4 and NH4 2SO4. Inaddition, increasing NH4 H2PO4 concentration to 0.250 M increased enzyme production. Finally, additional glucosewas not effective on lactase production
