Publication number: 20170306309Abstract: The present invention relates to variants having glucoamylase activity with improved properties and to compositions comprising these variants suitable for use for example in the production of a food, beverage (e.g. beer), feed, biochemical, or biofuel. Also disclosed are DNA constructs encoding the variants and methods of producing the glucoamylase variants in host cells. Furthermore, different methods and uses related to glucoamylases according to the invention are disclosed, such as in a brewing process.Type: ApplicationFiled: April 12, 2017Publication date: October 26, 2017Applicant: DuPont Nutrition Biosciences APSInventors: Jacob Flyvholm CRAMER, Peter Edvard DEGN, Igor NIKOLAEV, Viktor ALEKSEYEV, Casper Willem VROEMEN, Daniel TORRES PAZMINO, Neville Marshall FISH

Patent number: 9469848Abstract: The present invention relates to combinatorial variants of a parent glucoamylase that have altered properties for reducing the synthesis of condensation products during hydrolysis of starch. Accordingly, the variants of a parent glucoamylase are suitable such as for use within brewing and glucose syrup production. Also disclosed are DNA constructs encoding the variants and methods of producing the glucoamylase variants in host cells.Type: GrantFiled: June 30, 2011Date of Patent: October 18, 2016Assignee: DUPONT NUTRITION BIOSCIENCES APSInventors: Peter Edvard Degn, Richard R. Bott, Casper Willem Vroemen, Martijn Silvan Scheffers, Wolfgang Aehle, Elin Petersen

Publication number: 20150240223Abstract: A fungal alpha amylase is provided from Talaromyces emersonii (TeAmy1), along with variants of the same. TeAmy1 has an optimal pH of 3.5 and is operable over a temperature range of at least 30 75° C., allowing the enzyme to be used in combination with a glucoamylase in a saccharification reaction. This obviates the necessity of running a saccharification reaction as a batch process, where the pH and temperature must be readjusted for optimal use of the alpha amylase or glucoamylase. TeAmy1 also catalyzes the saccharification of starch substrates to an oligosaccharide composition significantly enriched in DP2 and (DP1+DP2) compared to the products of saccharification catalyzed by an alpha amylase from Aspergillus kawachii. This facilitates the utilization of the oligosaccharide composition by a fermenting organism in a simultaneous saccharification and fermentation process, for example.Type: ApplicationFiled: September 17, 2013Publication date: August 27, 2015Inventors: Ling Hua, Zhongmei Tang, Casper Willem Vroemen, Bo Zhang, Zhenghong Zhang
