Abstract
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.
