Abstract:
The present invention relates to isolated polypeptides having glucoamylase activity, catalytic domains, carbohydrate binding domains and polynucleotides encoding the polypeptides, catalytic domains or carbohydrate binding domains. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides, catalytic domains or carbohydrate binding domains.
Abstract:
The invention relates to a process of fermenting plant material in a fermentation medium into a fermentation product using a fermenting organism, wherein one or more carbonic anhydrases are present in the fermentation medium.
Abstract:
The present invention relates to enhancing sludge dewaterability by adding an alpha-amylase to the sludge prior to conventional conditioning and dewatering operations.
Abstract:
The present invention provides improved fermentation processes, including for use in an ethanol production process. The improved fermentation processes include applying at least one fatty acid oxidizing enzyme (such as a lipoxygenase) in a fermentation process. The improved fermentation process may also involve the addition of various additional enzymes and growth stimulators for the fermenting microorganisms, including vitamins and mineral.
Abstract:
The present invention relates to a method for producing cheese from cows milk wherein milk or a fraction of milk is treated with a phospholipase and heat treated during or after phospholipase treatment, and the treated milk or milk fraction is used for producing cheese. The methods results in a decreased oiling off of the cheese when heated and/or in an improved cheese yield.
Abstract:
A method of extracting a polypeptide of interest from a fermentation broth comprising: i) adjusting the pH close to pI of the polypeptide of interest; ii) adding a non-ionic surfactant with a hydrophile-lipophile balance (HLB) of 12 or lower; iii) cooling the mixture for solubilization and incubating at above cloud point for extraction; iv) phase separating at below cloud point to obtain liquid-liquid-solid fractions; and v) recovering the surfactant-rich top phase containing the polypeptide of interest.
Abstract:
The present invention relates to methods for deinking wastepaper by pulping wastepaper at a pH between 4 and 8.5 in the presence of deinking agents comprising a lipase and a fatty acid ester and removing the thereby dislodged ink particles.
Abstract:
The present invention provides improved fermentation processes, including for use in an ethanol production process. The improved fermentation processes include applying esterases (such as, lipases, phospholipases and cutinases), laccases, phytases and/or proteases to a fermentation process. The improved fermentation process may also involve the addition of various growth stimulators for the fermenting microorganisms, including vitamins and mineral.
Abstract:
In the production of pulp and paper from starch-containing paper, the deinking effect can be improved by including treatment with both a starch-degrading enzyme and a pectate lyase. The process comprises enzyme treatment during or after disintegration of the paper to produce pulp, followed by separation of ink particles.
Abstract:
The present invention relates to variants of a parent alpha-amylase. The present invention also relates to polynucleotides encoding the variants and to nucleic acid constructs, vectors, and host cells comprising the polynucleotides, and methods of using the variant enzymes.
