Use of rLDM 1-6 and other ligninolytic enzymes in the bleaching of kraft pulp

摘要

The subject invention concerns a novel enzymatic process for bleaching kraft pulp. Specifically, novel enzymes, designated rLDM TM , and other ligninolytic enzymes present in the extracellular growth medium from a fermentation of Phanerochaete chrysosporium, are used to bleach kraft pulp to a desired lighter color.
