Chakrabarty] Summary: The production of amylolytic enzymes by a thermophilic cellulolytic fungus,Myceliophthora thermophila D14 was investigated by batch cultivation in Czapek-Dox medium at 45° C. Among various nitrogenous compounds used, NaNO3 and KNO3 were found to be the best for amylase production. Starch, cellobiose and maltose induced the synthesis of amylase while glucose, fructose, galactose, lactose, arabinose, xylose, sorbitol, mesoinositol and sucrose did not. Calcium ions had the most stimulating effect on enzyme formation amongst many ions investigated. The synthesis of amylolytic enzymes was dependent on growth and occurred predominantly in the mid-stationary phase. The enzyme was active in a broad temperature range (50° C-60° C) and displayed activity optima at 60° C and pH 5.6.
