<p>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.</p> |
