Methods and compositions to improve the nutritional value of lignocellulosic biomass

摘要

The present invention relates to a method of preparing a feed additive composition comprising: (a) physically and/or chemically and/or biologically pre-treating lignocellulosic biomass, (b) admixing the physically and/or chemically and/or biologically pre-treated lignocellulosic biomass with an enzyme composition, wherein the enzyme composition comprises at least the following activities: endoglucanase activity, &bgr;-glucosidase activity and endoxylanase activity and wherein the enzyme composition comprises no, or substantially no, &bgr;-xylosidase activity and/or no, or substantially no α-L- arabinofuranosidase activity, (c) incubating same for at least about 3-120 hours, (d) and optionally drying and/or optionally packaging.
