GRANULAR STARCH CONVERSION ENZYMES AND METHODS
Described are methods and compositions relating to granular starch-converting glucoamylases and α-amylases. The enzymes can be used to perform enzymatic starch hydrolysis of granular starch at or below the gelatinization temperature of insoluble granular starch.
Genetically modified trehalose-expressing yeasts and fermentation processes using such genetically modified yeasts
The present invention relates to genetically engineered yeasts having a heterologous trehalase gene and fermentation processes for using such yeasts. The yeasts can express trehalase in a quantity sufficient to convert significant amounts of trehalose to glucose, thereby improving the yield of the product in a fermentation, and/or reducing or eliminating the need to add exogenous trehalase to the fermentation. The yeasts can also include other heterologous genes for expressing enzymes useful for improving yield and/or for reducing or eliminating the need to add exogenous enzymes to the fermentation.
SUGAR-PRODUCING AND TEXTURE-IMPROVING BAKERY METHODS AND PRODUCTS FORMED THEREFROM
Novel yeast-raised and other bakery products and methods of making those products are provided. The products are formed from dough comprising a thermally-stable amyloglucosidase, and a raw starch degrading amyloglucosidase and/or an anti-staling amylase. The level of added sugar included in the dough can be substantially reduced, and even eliminated, while still achieving a sweet product. Additionally, the resulting bakery product is free of, or at least substantially free of, fructose. The final baked product will also have improved texture properties, including superior firmness, resilience, and adhesiveness and can be made with a reduced amount of yeast.
POLYPEPTIDE VARIANTS
Detergent compositions including polypeptide variants and methods of cleaning and/or treatment of surfaces using such compositions, and fabric treatment compositions including polypeptide variants. The compositions may include surfactants: anionic, nonionic and/or cationic.
Polypeptide variants
The present invention relates to polypeptide variants and methods for obtaining variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.
Engineered yeast strains with signal sequence-modified glucoamylase polypeptides and enhanced ethanol production
The invention is directed to non-natural yeast able to secrete significant amounts of glucoamylase into a fermentation media. The glucoamylase can promote degradation of starch material generating glucose for fermentation to a desired bioproduct, such as ethanol. The glucoamylase can be provided in the form of a glucoamylase fusion protein having secretion signal that is: derived from at least AA 1-19 of SEQ ID NO: 73, (ii) an amino acid sequence of at least AA 1-19 of SEQ ID NO: 74, (iii) SEQ ID NO: 77 (An aa), (iv) SEQ ID NO: 75 (Sc IV), (v) SEQ ID NO: 76 (Gg LZ), or (vi) SEQ ID NO: 78(Hs SA).
Modified filamentous fungal host cell for encoding a secreted polypetide of interest
The present invention relates to filamentous fungal cells secreting a polypeptide of interest, wherein the expression of a citT gene is altered, reduced or eliminated compared to a non-mutated otherwise isogenic or parent cell, and methods of producing a secreted polypeptide of interest in said cells as well as methods of producing said cells.
ENZYMES FOR INFUSION MASHING IN ADJUNCT BREWING TECHNICAL FIELD
The present invention relates to methods of mashing 100% adjunct grists. More specifically, the instant disclosure provides methods and compositions wherein an alpha-amylase in combination with an maltogenic alpha amylase and/or glucoamylse to make a non-malt wort composed by adjunct raw materials.
Aqueous fermentation feedstock and a method for the production thereof

The feedstock includes glucose and dextrose oligomers, wherein (i) glucose concentration is in a range between 10 gram/Liter (g/L) and 150 g/L; (ii) dextrose oligomers concentration is in a range between 50 g/L and 300 g/L; and optionally (iii) slurried particles of less than 0.5 micron; (iv) slurried particles of more than 0.5 micron, wherein a content of such suspended particles of more than 0.5 micron is less than 30 g/L; (v) ash at a concentration in a range between 20 g/L and 50 g/L; (vi) lactate at a concentration in a range between 0.5 g/L and 10 g/L; (vii) protein at a concentration in a range between 5 g/L and 50 g/L; (viii) corn oil at a concentration of less than 10 g/L; and/or (ix) glycerol at a concentration in a range between 1 g/L and 30 g/L.
Glycerol free ethanol production
The invention relates to a recombinant yeast comprising a recombinant yeast comprising a nucleotide sequence coding for a glycerol dehydrogenase, a nucleotide sequence coding for a ribulose-1,5-biphosphate carboxylase oxygenase (EC 4.1.1.39); a nucleotide sequence coding for a phosphoribulokinasey (EC 2.7.1.19); a nucleotide sequence allowing the expression of a glucoamylase (EC 3.2.1.20 or 3.2.1.3); and optionally a nucleotide sequence coding for a glycerol transporter. This cell can be used for the production of ethanol and advantageously produces little or no glycerol.
