Abstract
The biosynthesis of pectinases by Aspergillus foetidus was studied in litre conical flasks by the surface culture method using wheat bran as solid substrate. The parameters studied were the depth of the wheat bran, selection of diluents and methods for the extraction of the enzyme. Wheat bran was found to be an ideal substrate providing all nutrients essential for mould growth and enzyme formation. 0.1N HC1 as diluent gave optimum results of both pectinesterase and polygalacturonase. The enzyme production reached maximum 48 hr. after incubating at 30°.
