摘要:
In one aspect, the invention is directed to polypeptides having an amylase and/or glucoamylase activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. In one aspect, the polypeptides of the invention can be used as amylases, for example, alpha amylases, to catalyze the hydrolysis of polysaccharide, oligosaccharide or starch into sugars. In one aspect, the invention provides delayed release compositions comprising an desired ingredient coated by a latex polymer coating. In alternative embodiments, enzymes are used to make biofuels, e.g., ethanol, butanol, propanol, or a gasoline-ethanol mix, including a bioethanol, biopropanol, biobutanol, or a biodiesel, or for any form of fuel or biomass processing.

The invention provides polypeptides having a lignocellulolytic activity, e.g., a glycosyl hydrolase, a cellulase, an endoglucanase, a cellobiohydrolase, a beta- glucosidase, a xylanase, a mannanse, a xylosidase (e.g., a β- xylosidase), an arabinofuranosidase, and/or a glucose oxidase activity, polynucleotides encoding these polypeptides, and methods of making and using these polynucleotides and polypeptides. In one aspect, the invention provides polypeptides that can enzymatically process (hydrolyze) sugarcane bagasse, i.e., for sugarcane bagasse degradation, or for biomass processing, and polynucleotides encoding these enzymes, and making and using these polynucleotides and polypeptides. In one embodiment, the invention provides thermostable and thermotolerant forms of polypeptides of the invention. The polypeptides of the invention can be used in a variety of pharmaceutical, agricultural and industrial contexts; for example, the invention provides a multi-enzyme system that can hydrolyze polysaccharides in a bagasse component of sugarcane processed in sugar mills. The invention provides enzymes for the bioconversion of lignocellulosic residues into fermentable sugars; and these sugars can be used as a chemical feedstock for the production of ethanol and fuels, including biofuels such as bioethanol, biopropanol, biobutanol and biodiesels.
