Xylanase Production in Submerged Fermentation by T. Longibractium MTCC-936

Abstract

Two thermophilic strains of fungi T.longibroctium MTCC 936 and
T. harzimum MTCC 792 were examined for their ability to produce
Xylanose in submerged fermentations. The higher enzyme odivity 27.02 was obtained in submerged fermentation by T.longibroctium. The optimum yield of xylonase was obtained with xylan as a substrate along with combination of three nitrogen sources (Urea,(NH₄)₂SO₄ and Bodopeptone 0.1% each) of pH 6 and temperature 55°C. This enzyme was purified by salt precipitation and ultra filtration technique.
