ABSTRACT:
Novel lignin-degrading enzymes designated rLDM.TM.1, rLDM.TM.2, rLDM.TM.3, rLDM.TM.4, rLDM.TM.5, and rLDM.TM.6 are isolated and purified to the essentially pure form, wherein each rLDM.TM. is substantially free of other rLDM.TM. and native proteins, from the extracellular medium of a novel mutant microbe. The novel mutant, designated SC26, produces large amounts of the rLDM.TM., thus facilitating the isolation and purification of them. These rLDM.TM. are useful in pulping processes to degrade and/or modify lignin.
