This invention provides novel enzyme compositions using newly identified and isolated C. lucknowense enzymes, including CBH Ib CBH IIb, EG II, EG VI, β-glucosidase, and xylanase II in conjunction with previously identified enzymes CBH Ia, CBH IIa (previously described as Endo 43), and EG V. These enzyme compositions demonstrate an extremely high ability to convert lignocellulosic biomass (e.g., Avicel, cotton, Douglas fir wood pretreated by organosolv) to glucose. CBH Ia and IIb, which both have a cellulose-binding module (CBM) displayed a pronounced synergism with three major endoglucanases (EG II, EG V, EG VI) from the same fungus in hydrolysis of cotton as well as a strong synergy with each other. The enzyme compositions are effective in hydrolysis of the lignocellulosic biomass.

Conjugated polysaccharide fabric detergent and conditioning products

A polysaccharide conjugate comprises a polysaccharide with an attached entity having a molecular weight of at least 5000, the polysaccharide conjugate being capable of binding to cellulose. Preferred polysaccharides include tamarind seed xyloglucan, locust bean gum and enzyme modified guar. The attached entity is suitably a protein such as an enzyme, antibody or antibody fragment, or a particle possibly having a benefit agent such as a fragrance associated therewith. Because the polysaccharide conjugate binds to cellulose, which is present in cotton and other fabrics, paper, etc., binding of the conjugate to cellulose brings the attached entity into close proximity to a surface of or containing cellulose. The invention thus enables targeting of attached entities to such surfaces. The invention also provides a product incorporating the polysaccharide conjugate of the invention. The product is conveniently a laundry product such as a fabric washing product, e.g. a detergent product, or a fabric conditioning product. In this case the attached entity may be an enzyme, a particle bearing fragrance, etc. The invention also provides a method of targeting binding of an entity to cellulose by use of the polysaccharide conjugate of the invention.
