Claims (9)

1. Postupak za proizvodnju šećera ili šećera od lignoceluloznog materijala, koji obuhvaća: a) predobradu lignoceluloznog materijala prije enzimatske obrade izlaganjem (vrućoj) vodi, pari (eksplozija pare), kiselini, bazi, otapalu, toplini, peroksidu, ozonu, mehaničkom usitnjavanju, brušenju, mljevenju ili brzom smanjenju tlaka, kombinaciji bilo koje dvije ili više njih; b) predsaharifikaciju lignoceluloznog materijala inkubacijom s enzimom ili smjesom enzima; c) dovođenje u kontakt lignoceluloznog materijala s (i) polipeptidom koji sadrži aminokiselinsku sekvencu navedenu u SEQ ID NO:2 ili njegovom varijantom polipeptida, pri čemu varijanta polipeptida ima najmanje 98% istovjetnosti sekvence sa sekvencom navedenom u SEQ ID NO:2, pri čemu polipeptid ima aktivnost beta-glukozidaze i pri čemu varijanta polipeptida ima katalitički ostatak Asp277 - Glu505 (položaji kao u SEQ ID NO: 2), ili (ii) pripravkom koji sadrži polipeptid iz (i).1. Process for the production of sugar or sugar from lignocellulosic material, which includes: a) pretreatment of lignocellulosic material before enzymatic treatment by exposure to (hot) water, steam (steam explosion), acid, base, solvent, heat, peroxide, ozone, mechanical shredding, grinding, grinding or rapid pressure reduction, a combination of any two or more of them ; b) pre-saccharification of lignocellulosic material by incubation with an enzyme or a mixture of enzymes; c) bringing the lignocellulosic material into contact with (i) a polypeptide containing the amino acid sequence listed in SEQ ID NO:2 or a polypeptide variant thereof, wherein the polypeptide variant has at least 98% sequence identity to the sequence listed in SEQ ID NO:2, wherein the polypeptide has beta-glucosidase activity and wherein the polypeptide variant has the catalytic residue Asp277 - Glu505 (positions as in SEQ ID NO: 2), or (ii) by a preparation containing the polypeptide from (i). 2.
