Industrial waste materials has become one of the global challenges and remained as a centre of attraction for the production of value added materials such as bioethanol and oligosaccharides. In an attempt to address the current situation, CS428, a new soil isolate capable of producing industrially applicable lignocellulose degrading enzyme, was isolated from Korean soil. An extracellular xylanase produced by the strain in culture medium containing 1.25% beech wood was purified and biochemically characterized. Enzyme production was highest at 2 to 3 days and the medium pH was found increasing with the increase in enzyme activity. The enzyme was thermostable and displayed broad range of pH stability (from pH 4.0 to pH 12.0). Further, the enzyme showed maximum activity at pH 12.0 and at 60°Cwith activity in broad temperature range (30 to 75°C). Because of high range of pH and thermostability, this enzyme can be a good candidate in the field of bioindustries.
