  • Recombinant yeast and use thereof
    Patent number: 10253337
    Abstract: A recombinant yeast that expresses both an ?-amylase (SEQ ID NO: 1) and a glucoamylase (SEQ ID NO: 2) from Talaromyces emersonii (recently re-named as Rasamsonia emersonii) is provided. The use of the recombinant yeast in a process for producing an alcohol, in particular a biofuel, from starch or sugars is also described.
    Type: Grant
    Filed: December 4, 2017
    Date of Patent: April 9, 2019

  • Method for enhancing cellobiose utilization
    Patent number: 9512448
    Abstract: The present invention relates to methods for improving a host cell's ability to utilize the disaccharide cellobiose. In some embodiments, a transformed cell expresses intracellular ?-glucosidase. In other embodiments, a transformed host cell is able to grow on media wherein cellobiose is the sole carbon source. In other embodiments, selection methods are provided which improve a host cell's ability to grow on cellobiose-containing media.
