Publication number: 20210163995Abstract: The present disclosure concerns a process for fermenting a biomass with a reduced dose of a purified exogenous enzyme (which can be, for example a purified exogenous glucoamylase). The process comprises contacting a biomass (which may comprise starch) with a recombinant yeast host cell. The recombinant yeast host cell has a genetic modification for expressing a heterologous polypeptide having starch or dextrin hydrolase activity (which may be, for example, from a glucoamylase). The nucleic acid molecule encoding the heterologous polypeptide having starch or dextrin hydrolase activity comprises allowing the secretion of the heterologous polypeptide.Type: ApplicationFiled: November 25, 2020Publication date: June 3, 2021Inventors: Aaron Argyros, Alexandra Panaitiu, Charles Rice, Matthew B.

Publication number: 20190376052Abstract: The invention relates to polypeptides having glucanase, e.g., endoglucanase, mannanase, xylanase activity or a combination of these activities, and polynucleotides encoding them. In one aspect, the glucanase activity is an endoglucanase activity (e.g., endo-1,4-beta-D-glucan 4-glucano hydrolase activity) and comprises hydrolysis of 1,4-beta-D-glycosidic linkages in cellulose, cellulose derivatives (e.g., carboxy methyl cellulose and hydroxy ethyl cellulose) lichenin, beta-1,4 bonds in mixed beta-1,3 glucans, such as cereal beta-D-glucans or xyloglucans and other plant material containing cellulosic parts. In addition, methods of designing new enzymes and methods of use thereof are also provided. In alternative aspects, the new glucanases e.g., endoglucanases, mannanases, xylanases have increased activity and stability, including thermotolerance or thermostability, at increased or decreased pHs and temperatures.Type: ApplicationFiled: May 28, 2019Publication date: December 12, 2019Inventors: Brian Steer, Shaun Healey, Alireza Esteghlalian, Stacy Marie Miles, Kenneth Barrett, Rene Quadt

Patent number: 9139950Abstract: An automatic lint filter cleaning and lint collection system for a laundry dryer. The apparatus comprises a lint filter pivot chamber, a lint collection chamber, a lint filter housing pivotably mounted between the pivot chamber and collection chamber, a flange between the pivot chamber and collection chamber wherein the filter housing is biased into abutment with the flange, a lint collection container, an auger rotatably mounted within the collection chamber, and a drive assembly operably connected to the lint filter housing and auger. The drive assembly is operable to pivot the filter housing away from the flange and then to release the filter housing such that the filter housing forcibly returns into abutment with the flange and thereby causes the lint filter to release lint into the collection chamber. The drive assembly is operable to rotate the auger and thereby move lint from the collection chamber into the collection container.Type: GrantFiled: October 31, 2014Date of Patent: September 22, 2015Inventors: Kenneth A. Barrett, Roderic N. Uphaus

Patent number: 4429881Abstract: A miniature golf course including a perimeter fence made of hinged segments of blocks that are slightly higher than the diameter of the golf ball. There is a center section having a tunnel member in the rear thereof and another tunnel member in the front opposite the starting area. Within the center section is a removable ramp having simulated traps. On each side of the center section are fences parallel to the outside perimeter fences connected to each corner of the tunnel members. Pegs and openings within the members to receive the pegs enable the center section to be quickly and easily assembled. Three fairways are formed, one on each side of the center section, and one through the center section. A single target hole is located between the rear tunnel member and the rear of the perimeter fence. A blocking member is movable and adapted to be located to close off two fairways by connecting it to a corner of the front tunnel and the perimeter fence opposite the starting area.Type: GrantFiled: September 2, 1981Date of Patent: February 7, 1984Inventor: Kenneth A.
