ABSTRACT:
A method of removing color from wood pulp is disclosed. The method comprises the steps of preparing a wood pulp, treating the wood pulp with the xylanase wherein the xylanase is capable of releasing chromophores from the pulp and extracting the wood pulp to remove chromophores. Also disclosed are substantially purified preparations of xylanase enzymes from bacterial isolates. The xylanase is preferrably isolated xyl 3 obtained from Streptomyces roseiscleroticus NRRL B-11019, wherein xyl 3 has a molecular weight of approximately 21 kD as determined by SDS-gel electrophoresis and a pH optima of pH 5.0-7.0.
