Streptomyces sp. CS802, recently isolated from Korean soil, produced xylanase in corncob medium. An extracellular xylanase (Xyn802) was purified by a single step gel filtration and biochemically characterized. It showed high activity in extremely alkaline condition with optimum pH at 12.0 and exhibited stability between pH 7.5 and 13.0. It produced xylobiose and xylotriose as the major products from xylan, suggesting its endoxylanase nature. N-terminal amino acid sequences of Xyn802 were ADRNANRD which are significantly different from the reported xylanase. The activity was enhanced by various detergents and a reducing agent and stable in range of organic solvents. Xyn802 produced by utilizing corncob, an agro-waste material, might be a novel xylanase based on its peculiar biochemical characteristics. Due to lack of cellulase activity and ability of producing xylooligosaccharides from xylan, Xyn802 can be a suitable candidate for pre-bleaching of paper pulps and generating xylooligosaccharides.
