Production of Pectinase and Xylanase by Aspergillus sojae and Its Effect on the Qualitative Improvement of Jute Fibre

Abstract

Extracellular enzymes, polygalacturonase, pectinlyase and xylanase were produced from Aspergillus sojae by solid state fermentation on wheat bran medium. The growth and enzyme production were highest at 50% added moisture and 35°C. The pectinolytic enzyme preparation, which was extracted from the fermented bran, was used for the improvement of jute cuttings. Enzyme-treated fibre contained less amount of hemicellulose and pectic materials than untreated fibre and was improved in fibre quality. A commercial enzyme, Flaxazyme (Novo), was examined comparatively.
