  • Patent number: 10400228
    Abstract: Truncated pullulanases having an N-terminal deletion in a parental pullulanase are provided. These truncated pullulanases have altered properties as compared to the parental pullulanase, including an increased saccharification rate and higher catalytic activity at acidic pH values below 4.5 and higher temperatures of up to 64° C. These truncated pullulanase also have improved thermal stability as compared to the parental enzyme. Also provided are compositions containing the truncated pullulanases and a glucoamylase, and processes for applying the truncated pullulanases and compositions in the starch industry. Polynucleotides that encode the truncated pullulanases, and recombinant host cells for producing the truncated pullulanases are also described.

  • Patent number: 8916363
    Abstract: This invention provides novel enzyme compositions using newly identified and isolated C. lucknowense enzymes, including CBH Ib CBH IIb, EG II, EG VI, ?-glucosidase, and xylanase II in conjunction with previously identified enzymes CBH Ia, CBH IIa (previously described as Endo 43), and EG V. These enzyme compositions demonstrate an extremely high ability to convert lignocellulosic biomass (e.g., Avicel, cotton, Douglas fir wood pretreated by organosolv) to glucose. CBH Ia and IIb, which both have a cellulose-binding module (CBM) displayed a pronounced synergism with three major endoglucanases (EG II, EG V, EG VI) from the same fungus in hydrolysis of cotton as well as a strong synergy with each other. The enzyme compositions are effective in hydrolysis of the lignocellulosic biomass.

  • Patent number: 7268221
    Abstract: This invention relates to a method for utilizing less purified starch in fermentation processes. One example is a recombinant E. coli containing a exogenous extracellular isoamylase activity that is capable of utilizing small oligomers containing (1,6) linkages (including but not limited to isomaltose and panose) in fermentations to produce useful products. The invention is useful in large-scale industrial biofermentations by reducing the cost of the substrate carbohydrate.

  • Patent number: 7060482
    Abstract: 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.
