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 polysaccharides,
cellulose, lignocellulose,
hemicellulose,
lignin,
starch, sugars,
sugar oligomers, carbohydrates, complex carbohydrates,
chitin, heteroxylans, glycosides,
xylan-,
glucan-,
galactan-, or
mannan-decorating groups; 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.
