CELLULOSE AND/OR HEMICELLULOSES DEGRADING ENZYMES FROM MACROPHOMESIA PHASEOLESIA AND USES THEREOF

摘要

The present invention provides nucleotide sequences of Macrophomina phaseolina ("M. phaseolina") that encodes o proteins/enzymes with cellulolytic activity, including a cellulase activity, a endoglucanase, a cellobiohydrolase, a b-glucosidase, a aglucosidase, a xylanase, a mannanse, a b-xylosidase, a a-xylosidase, a galactosidase, an arabinofuranosidase, a a- fucosidases, a b- galactanase, an unsaturated b-glucuronyl hydrolase and/or oligomerase activity. Vectors, expression constructs and host cells co prising and/or consisting of the nucleotide sequences of the enzyme genes are also provided. The invention further provides methods for producing the enzymes and methods for modifying the enzymes in order to improve their desirable characteristics. The enzymes of the invention can be used in a variety of, but not limited to, pharmaceutical, agricultural, food and feed processing, biofuel, energy efficiency and industrial contexts. These enzymes are also useful for complete hydrolysis of lignocellulosic biomass into simple sugar that can then be fermented to liquid fuels and chemical feedstocks.
