Patent number: 7112429Abstract: The invention provides a thermal tolerant mannanase that is a member of the glycoside hydrolase family. The invention further discloses this mannanase as ManA. ManA has been isolated and characterized from Acidothermus cellulolyticus. The invention further provides recombinant forms of the identified ManA. Methods of making ManA polypeptides, including fusions, variants, and derivatives, are also disclosed. Methods of using mannanase A, including for the processing of food and for use in food stuffs as bulking agents and the like, are also disclosed.Type: GrantFiled: July 28, 2001Date of Patent: September 26, 2006Assignee: Midwest Research InstituteInventors: Shi-You Ding, William S. Adney, Todd B. Vinzant, Michael E. Himmel

Patent number: 7060482Abstract: The present invention is directed to thermostable xylanase enzymes are suitable for feed pelleting applications. The novel xylanase enzymes comprise at least 40% of their optimal activity from a pH range from about pH 3.5 to about pH 6.0, and from about 40 to about 60° C., and exhibit at least 30% of their optimal activity after a pre-incubation step for 30 minutes at 70° C. in the presence of 40% glycerol. Also disclosed are modified xylanase molecules comprising either a basic amino acid at position 162 (TrX numbering), or its equivalent position in other xylanase molecules, at least one disulfide bridge, or a combination thereof. The thermostable xylanase molecules of the present invention have a physiological temperature and pH optima and are useful as animal feeds additives since they can withstand the heat associated with feed sterilization and pellet formation, yet they exhibit optimal activity within an animal to aid in breakdown of ingested feed.Type: GrantFiled: November 16, 1999Date of Patent: June 13, 2006Assignee: National Research Council of CanadaInventors: Wing L. Sung, Jeffrey S. Tolan
