Patent number: 10077436Abstract: Described herein are beta-glucosidase enzymes that have improved beta-glucosidase activity compared to a control beta-glucosidase enzyme. The improved beta-glucosidase enzymes are useful for converting a cellulosic biomass to fermentable sugars such as glucose. Also described are isolated polynucleotides that encode polypeptides having improved beta-glucosidase activity, expression cassettes for expressing the improved beta-glucosidase polypeptides, and cells, such as yeast cells, transformed with the expression cassettes.Type: GrantFiled: September 16, 2014Date of Patent: September 18, 2018Assignee: EDENIQ, INC.Inventors: Lan Sun, Ngim Muy Ung Ferrell, Deepak Singh, Jennifer Headman, Mei-Hua Chu, Michael Guerini, Sandra Jacobson
