Abstract
Five xylanases are purified from the microorganism, Microtetraspora flexuosa,preferably strain ATCC 35864. Each biochemically unique xylanase is thermostable and has optimal activity in alkaline conditions. These enzymes are excellent candidates for enhancing the delignification and bleaching of pulp. Furthermore, treating the pulp with the above enzymes prior to bleaching may reduce the amount of chlorine containing and/or peroxide chemicals required in the bleaching process.
