Abstract: The present invention relates to a cellulose-degrading enzyme composition comprising one or more cellobiohydrolase and/or endoglucanase enzyme, and an effective amount of an isolated GH16 polypeptide, where the presence of the isolated GH16 polypeptide in the enzyme composition increases the rate or extent of degradation of a cellulosic substrate compared to an equivalent dosage of a corresponding cellulose-degrading enzyme composition lacking the at least one isolated GH16 polypeptide. The present invention also relates to a method for producing fermentable sugars from a cellulosic substrate using the above cellulose-degrading enzyme composition and to genetically modified microbes for produced the above cellulose-degrading enzyme composition.

Abstract: The present invention relates to novel polypeptides and enzymes (e.g., thermostable proteins and enzymes) having activities relating to biomass processing and/or degradation (e.g., cell wall deconstruction), as well as polynucleotides, vectors, cells, compositions and tools relating to same, or functional variants thereof. More particularly, the present invention relates to secreted enzymes that may be isolated from the fungi, Scytalidium thermophilum strain CBS 625.91, Myriococcum thermophilum strain CBS 389.93, and Aureobasidium pullulans strain ATCC 62921. Uses thereof in various industrial processes such as in biofuels, food preparation, animal feed, pulp and paper, textiles, detergents, waste treatment and others are also disclosed.
