Abstract:
The present invention provides methods for single-bath desizing, scouring and bleaching of cellulosic materials, which are carried out by contacting the cellulosic simultaneously or sequentially with an enzyme system and a peracid bleaching system under conditions that do not require emptying the bath or rinsing the cellulosic materials between desizing, scouring and bleaching steps.
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 relates to isolated polypeptides having glucoamylase activity and isolated polynucleotides encoding the polypeptides. 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.

Abstract:
The present invention relates to polypeptides comprising a carbohydrate-binding module amino acid sequence and an alpha-amylase amino acid sequence as well as to the application of such polypeptides.
Abstract:
This disclosure relates to methods of enhancing sludge dewaterability by adding an alpha-amylase to the sludge prior to conventional conditioning and dewatering operations. A method of treating sludge is also disclosed including contacting sludge with an alpha-amylase and removing water from the sludge.
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.
