Abstract: The invention provides methods for producing products comprising improved host cells genetically engineered to have uncoupled productive and catabolic pathways. In particular, the present invention provides host cells having a modification in nucleic acid encoding an endogenous enzymatic activity that phosphorylates D-glucose at its 6th carbon and/or a modification of nucleic acid encoding an enzymatic activity that phosphorylates D-gluconate at its 6th carbon. Such improved host cells are used for the production of products, such as, ascorbic acid intermediates. Methods for making and using the improved host cells are provided. Nucleic acid and amino acid sequences for glucokinase and gluconokinase are provided.
Abstract: The present invention relates to filamentous fungal host cells and particularly Trichoderma host cells useful for the production of heterologous granular starch hydrolyzing enzymes having glucoamylase activity.

Abstract: Disclosed herein are novel phenol oxidizing enzymes naturally-produced by strains of the species Stachybotrys which possess a pH optima in the alkaline range and which are useful in modifying the color associated with dyes and colored compounds, as well as in anti-dye transfer applications. Also disclosed herein are biologically-pure cultures of strains of the genus Stachybotrys, designated herein Stachybotrys parvispora MUCL 38996 and Stachybotrys chartarum MUCL 38898, which are capable of naturally-producing the novel phenol oxidizing enzymes. Disclosed herein is the amino acid and nucleic acid sequence for Stachybotrys phenol oxidizing enzymes as well as expression vectors and host cells comprising the nucleic acid. Disclosed herein are methods for producing the phenol oxidizing enzyme as well as methods for constructing expression hosts.
Abstract: Described herein are methods to enhance the production of more highly fermentable carbohydrates in plants, especially forage grasses. The invention provides for transgenic plants transformed with expression vectors containing a DNA sequence encoding ferulic acid esterase I from Aspergillus, preferably A. niger. The expression vectors may optionally comprise a DNA sequence encoding xylanase from Trichoderma, preferably T. reesei. Expression of the enzyme(s) is targeted to specific cellular compartments, in specific tissues and under specific environmental conditions. Uses of this invention include, but are not limited to, forage with improved digestibility for livestock, and enhanced biomass conversion.
Abstract: The invention provides methods and host cells for the production of ascorbic acid intermediates. The invention also provides host cells having a modification in a polynucleotide that uncouples the catabolic pathway from the oxidative pathway by deleting the encoding for an endogenous enzymatic activity that phosphorylates D-glucose at its 6th carbon and/or a polynucleotide that has deleted the encoding for endogenous enzymatic activity that phosphorylates D-gluconate at its 6th carbon. Such host cells are used for the production of products, such as, ascorbic acid intermediates. Nucleic acid and amino acid sequences with inactivated enzymatic activity which phosphorylates D-glucose at its 6th carbon and inactivated enzymatic activity which phosphorylates D-gluconate at its 6th carbon are provided.
Abstract: A novel DNA is provided which encodes an enzyme having phytase activity isolated from Penicillium. Also provided for is a method of isolating DNA encoding an enzyme having phytase activity from organisms which possess such DNA, transformation of the DNA into a suitable host organism, expression of the transformed DNA and the use of the expressed phytase protein in feed as a supplement.

Abstract: During the desizing and enzymatic stonewashing of denim fabric and/or garments, redeposition of blue color often occurs back onto the surfaces of the denim. The invention relates to a redepositing or backstain inhibiting composition and a method requiring the inclusion of an added protease prior to, during or subsequent to the stonewashing process which reduces the redeposition of the blue dye and hence improves the stonewashing process when using redepositing or backstaining cellulases to give an appearance closer to that when using stones alone or nonredepositing cellulases in the stonewashing process.
