The present invention relates to uses of at least one carbohydrase in combination with an animal feed with a defined A/X fiber fraction, to an animal feed with a defined A/X fiber fraction and comprising at least one carbohydrase in an amount determined suitable to the A/X fiber fraction of the feed and methods of making thereof.

A method for treating a forage to increase digestibility by a ruminant comprises providing a forage for a ruminant comprising a level of ammonia that is from 0.0% to about 1.4% of dry matter (wt/wt). An alkali is applied at a dosage of from about 0.25% to about 0.75% of dry matter (wt/wt) to the forage. At least one exogenous carbohydrase enzyme is applied to the forage after application of the alkali and the forage is subsequently fed to the ruminant.

A process of recovering oil, comprising (a) converting a starch-containing material into dextrins with an alpha-amylase; (b) saccharifying the dextrins using a carbohydrate source generating enzyme to form a sugar; (c) fermenting the sugar in a fermentation medium into a fermentation product using a fermenting organism; (d) recovering the fermentation product to form a whole stillage; (e) separating the whole stillage into thin stillage and wet cake; (e′) optionally concentrating the thin stillage into syrup; (f) recovering oil from the thin stillage and/or optionally the syrup, wherein a protease and a phospholipase are present and/or added during steps (a) to (c). Use of a protease and a phospholipase for increasing oil recovery yields from thin stillage and/or syrup in a fermentation product production process.

Compositions comprising polypeptides having xylanase activity and polypeptides having arabinofuranosidase activity for use in e.g. animal feed. Polypeptides having arabinofuranosidase activity, polypeptides having xylanase activity and polynucleotides encoding the polypeptides. Nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptide.

The present invention provides process for treating crop kernels, comprising the steps of a) soaking kernels in water to produce soaked kernels; b) grinding the soaked kernels; c) treating the soaked kernels in the presence of an effective amount of an enzyme composition comprising: i) a protease, and ii) a cellulolytic composition, wherein step c) is performed before, during or after step b).

The presently disclosed subject matter relates to feed additive formulations for monogastric animal feed. Particularly, the disclosed formulations comprise an isolated xylanase enzyme and a B. licheniformis strain PWD-1. The feed additive formulations may further include B. amyloliquefaciens strain Ba-BPD1. The disclosed formulations are useful for addition to feeds for monogastric animals to synergistically improve the performance of the animals.

A method of producing a sugar liquid and a xylooligosaccharide includes Steps (1) to (3): Step (1): hydrolyzing a cellulose-containing biomass with a filamentous fungus-derived cellulase; Step (2): subjecting the hydrolysate of Step (1) to solid-liquid separation, and filtering the solution component through an ultrafiltration membrane to recover cellulase as a non-permeate, and to recover a sugar liquid as a permeate; and Step (3): reacting the recovered cellulase in Step (2) with a xylan-containing material, and recovering a xylooligosaccharide produced, Step (3) being independent from Step (1).

A method prepares a sugar solution from cellulose-containing biomass. The method includes step (1): a step of obtaining an endoxylanase hydrolysate by hydrolyzing the cellulose-containing biomass using endoxylanase derived from microorganisms of the Acremonium genus or the Aspergillus genus, step (2): a step of separating the endoxylanase hydrolysate into an endoxylanase hydrolysate solid and an endoxylanase hydrolysate liquid through solid-liquid separation, step (3): a step of obtaining a cellulase hydrolysate by hydrolyzing the endoxylanase hydrolysate solid using cellulase derived from a filamentous fungus, and step (4): a step of filtering the cellulase hydrolysate through an ultrafiltration membrane to recover a sugar solution from the filtrate side and collect an enzyme component from the non-filtrate side.
