Abstract:
The invention relates to processes of producing sugars and/or fermentation products from pretreated cellulosic material comprising the steps of: preconditioning pretreated cellulosic material; hydrolyzing using a cellulolytic enzyme preparation; and fermenting sugars with a microorganism; wherein a solid-liquid separation step, resulting in a solid fraction and a liquid fraction, is carried out: after preconditioning, but before hydrolysis; or after hydrolysis, but before fermentation; wherein phenol oxidizing enzyme and hemicellulase are present or added during preconditioning; after preconditioning, but before hydrolysis; or during hydrolysis.
Abstract:
The present invention relates to use of Caminibacter carbonic anhydrase in CO2 extraction, e.g., from flue gas, natural gas, biogas or ambient air. The Caminibacter carbonic anhydrases are especially well suited for these purpose due to their extreme thermostability.
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 relates to a process for enzymatic hydrolysis of cyclic oligomers of poly(ethylene terephthalate), which process comprises subjecting the cyclic oligomer to the action of one or more lipolytic and/or biopolyester hydrolytic enzyme(s) and a nonionic, nonlinear surfactant.
Abstract:
The present invention relates to methods for tenderizing meat. The methods comprise contacting meat with a tenderizing-effective amount of a thermolabile protease having limited substrate specificity.
Abstract:
The invention relates to a process for treatment of cellulosic material, as for example, knitted or woven cotton fabric, comprising the steps of preparing an aqueous enzyme solution comprising pectinase, treating the cellulosic material with an effective amount of the aqueous enzyme solution under alkaline scouring conditions; e.g., pH of 9 or above and a temperature of 50null C. or above, in a low calcium or calcium-free environment, yielding a modification of the cellulosic material such that exhibits an enhanced respond to a subsequent chemical treatment.
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.
Abstract:
The present invention relates to compositions comprising: a polypeptide having cellulolytic enhancing activity and a liquor. The present invention also relates to methods of using the compositions.
