The present invention relates to compositions to induce production of proteins, e.g., enzymes, e.g., amylases or biomass degrading enzymes in a host cell, and methods for increasing the yield of the proteins, e.g., enzymes produced. Such compositions comprise a caramelized sugar product. The methods described herein can also be used to enhance processing of biomass materials, e.g., to produce sugar products.

Compositions for enhanced enzyme production

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as hydroxy-carboxylic acids and hydroxy-carboxylic acid derivatives. A method includes treating a reduced recalcitrance lignocellulosic or cellulosic material with one or more enzymes and/or organisms (such as) to produce an alpha, beta, gamma and/or delta hydroxycarboxylic acid (such as lactic acid, glycolic acid); and converting the alpha, beta, gamma and/or delta hydroxy-carboxylic acid to the product (such as esters, polymers, and copolymers).

Processing biomass to obtain hydroxylcarboxylic acids

The processes disclosed herein include saccharifying cellulosic and/or lignocellulosic biomass and fermenting the sugars to produce a sugar alcohol.

Production of products from biomass

Disclosed is a method to incorporate xylose transport related genes into a yeast strain for lignocelluloses to ethanol production. More specifically, the invention relates to novelstrains NRRL Y-50463 and yeast strains having novel xylose transporter genes, the genes deposited as GenBank JF343555, GenBank JF343556, GenBank JF343557, GenBank JF343558, and GenBank JF343559. The yeast strains having said genes are deposited as Y-50465, Y-50466, Y-50746, Y-50747, Y-50748, and Y-50749.
