Purification of xylanase, beta-glucosidase, endocellulase, and exocellulase from a thermophilic fungus, Thermoascus aurantiacus

Abstract

A strain of thermophilic fungus, Thermoascus aurantiacus, was isolated from local soil. From the culture filtrates of the organism grown on blotting paper, a xylanase, beta-glucosidase, exocellulase, and endocellulase were obtained in large amounts in highly purified form by employing ion-exchange and gel-permeation chromatography. The xylanase was crystallized. The xylanase and endocellulase were stable at 70 degrees C for 8 h, whereas the beta-glucosidase and exocellulase were less stable at 70 degrees C.
