Disclosed are carbohydrate binding module variants, as well as variants of a glycoside hydrolase comprising the carbohydrate binding module variants. The variants having glycoside hydrolase activity comprising the carbohydrate binding module variants have improved stability in the presence of a protease, and are useful in detergent applications, such as laundry or dish wash.

The present disclosure provides a Klebsiella pneumoniae Y7-3 with a deposit number of CCTCC NO: M2019851. The strain can degrade corn stover into acetic acid, ethanol, and hydrogen, and can further metabolize into acetic acid, ethanol, 1,3-propanediol, lactic acid, and hydrogen.

The present invention relates to a process for the production of one or more fermentation product from a sugar composition, comprising the following steps: a) fermentation of the sugar composition in the presence of a yeast belonging to the genera Saccharomyces, Kluyveromyces, Candida, Pichia, Schizosaccharomyces, Hansenula, Kloeckera, Schwanniomyces or Yarrowia: and b) recovery of the fermentation product,
wherein the yeast comprises the genes araA, araB and araD and the sugar composition comprises glucose, galactose and arabinose.

The present invention relates to endoglucanase variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, expression vectors, and recombinant host cells comprising the polynucleotides; and methods of using the variants.
