  • Patent number: 9458440
    Abstract: The present invention discloses novel polypeptides and enzyme preparations containing them, which enhance the efficiency of the cellulosic degradation even at elevated temperatures. The polypeptides are produced by recombinant technology, and means for their production are described. The novel polypeptides are useful in processing biomass, and in biofuel, starch, textile, detergent, pulp and paper, food, feed or beverage industries. They may also be used e.g. in cleaning the interior of a dishwashing machine or for biofinishing or biostoning. The novel polypeptides are also useful in animal feed.

  • Patent number: 9434929
    Abstract: The present invention discloses novel polypeptides and enzyme preparations containing them, which improve the efficiency of cellulose and lignocellulose degradation even at elevated temperatures. The polypeptides can be produced using conventional recombinant DNA technologies. The related polynucleotides, vectors and host cells are also disclosed. The polypeptides and the enzyme preparations containing them are particularly useful in improving the efficiency of cellulose and lignocellulose degradation, in improving the quality of animal feed, in machine dishwashing applications, in detergent compositions, in pulp and paper, textile, food, baking or beverage industry.

  • Patent number: 9200267
    Abstract: The present invention relates to the production of sugar hydrolysates from cellulosic material. The method may be used, for example for producing fermentable sugars for the production of bioethanol from lignocellulosic material. Cellulolytic enzymes and their production by recombinant technology are described, as well as uses of the enzymes and enzyme preparations.

  • Patent number: 8975058
    Abstract: The present invention relates to production of fermentable sugars from lignocellulosic material by enzymatic conversion. The fermentable sugars are useful e.g. in the production of bioethanol. Novel polypeptides having endoglucanase activity, polynucleotides encoding them and vectors and host cells containing the polynucleotides are disclosed. A method for treating cellulosic material with the novel endoglucanase as well as uses of the enzymes and enzyme preparations and a method of preparing them are described.
