  • Patent number: 10982246
    Abstract: The present invention discloses an industrial scale method to obtain 1-kestose by the use of a recombinant fructosyltransferase (FTF), isolated from Festuca arundinacea, expressed constitutively in a non-saccharolytic yeast. In this invention, the recombinant FTF type sucrose:sucrose 1-fructosyltransferase (1-SSTrec) is produced constitutively, stable and at high yield, both in the culture supernatant and in intact cells of the host Pichia pastoris. Hence, the invention additionally provides a method for 1-SST production at industrial scale. The recombinant enzyme is then used for mass production of short-chain fructooligosaccharides (FOS), specifically 1-kestose, from sucrose. The method of the present invention establishes conditions that allow conversion rates where the synthesized FOS constitute above 55% (w/w) of the total sugars in the reaction mixture and the 1-kestose content reaches values higher than 90% (w/w) of the total FOS fraction.

  • Patent number: 10920229
    Abstract: The present invention relates to a method for improving the heterologous synthesis of a polyketide by E. coli and use thereof. The yield of the polyketide heterologously synthesized by E. coli is significantly increased by attenuating the expression of seventy-two genes, such as sucC and talB, in a host strain, wherein the highest yield increase rate can reach 60% or more. Currently, erythromycin is the most clear model compound in the study on the biosynthesis of polyketids. The production strain of the present invention enables massive accumulation of 6-deoxyerythronolide (6-dEB), an erythromycin precursor, in the fermentation process, laying the foundation for the industrial production of the heterologous synthesis of erythromycin by E. coli.
