New enzymes for splitting lignin

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 micr...

More Information
Summary: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.
