The present invention provides for a method for producing hydrogen peroxide comprising: (a) contacting a methanol with a methanol oxidase bound with a flavin adenine dinucleotide (FAD) cofactor, such that the methanol is oxidized into a formaldehyde and the FAD cofactor is reduced into FADH.sub.2; (b) contacting the formaldehyde with the methanol oxidase or a formate oxidase bound with a FAD cofactor, such that the formaldehyde is oxidized into a formate and the FAD is reduced into FADH.sub.2; and (c) contacting oxygen with one or more of the FADH.sub.2 to produce hydrogen peroxide and oxidize FADH.sub.2 into FAD. The present invention also provides for a fusion protein comprising any two or all of methanol oxidase, formate oxidase, and formaldehyde dismutase.

The present invention relates to a genetically modified microorganism for the production of 2,4-dihydroxybutyrate, by metabolic transformation of xylose via the 1,2,4-butanetriol intermediate. The invention also relates to a method for the production of 2,4-dihydroxybutyrate by culturing said genetically modified microorganism in a fermentation medium and recovering 2,4-DHB from said medium.

Disclosed are organisms comprising a highly expressed form of EC 1.2.3.1, and methods of their use including methods for efficient fermentation broth recycle, methods for improving bottoms recycle, methods for converting CO, CO.sub.2, and optionally H.sub.2 to ethanol and other oxygenated products, methods for preparing animal feed, and methods for preparing fertilizer.
