Enzymes which catalyze the degradation and modification of lignin

Abstract From the Canadian patent

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