Provided herein are compositions with enzymatically active enzymes produced recombinantly, enhanced protein content and methods for the preparation thereof.

A genetically modified organism comprising at least one nucleic acid sequence and/or at least one recombinant nucleic acid isolated from Alicyclobacillus acidocaldarius and encoding a polypeptide involved in at least partially degrading, cleaving, transporting, metabolizing, or removing polysaccharide, lignocellulose, hemicellulose, lignin, chitin, heteroxylan, and/or xylan-decorating group; and at least one nucleic acid sequence and/or at least one recombinant nucleic acid encoding a polypeptide involved in fermenting sugar molecules to a product. Additionally, enzymatic and/or proteinaceous extracts may be isolated from one or more genetically modified organisms. The extracts are utilized to convert biomass into a product. Further provided are methods of converting biomass into products comprising: placing the genetically modified organism and/or enzymatic extracts thereof in fluid contact with polysaccharides, cellulose, lignocellulose, hemicellulose, lignin, starch, sugars, sugar oligomers, carbohydrates, complex carbohydrates, chitin, heteroxylans, glycosides, and/or xylan-, glucan-, galactan-, or mannan-decorating groups.

The present invention relates to Sanxan gum preparation, and more particularly to a Sanxan gum synthetic strain-Sphingomonas sp. with a molecular marker and application thereof in Sanxan gum preparation by inoculating the Sphingomonas sp. strain (CGMCC No. 19480) into a culture medium containing a carbon source and a nitrogen source after sterilization, aeration fermentation and extraction. The invention solves the problems of no rapid identification of a product containing Sanxan gum and synthetic strain, and low performance indexes of a prepared Sanxan gum. It can quickly identify whether a product contains Sanxan gum. The main technical indicators of the prepared Sanxan gum products are significantly better than the existing products.
