  • Publication number: 20190330607
    Abstract: A method of providing a polypeptide having sugar-tolerant beta-glucosidase activity for hydrolysis of a lignocellulosic substrate to yield glucose and/or other sugars. Also provided is a host cell comprising and/or secreting said polypeptide and a kit-of-parts comprising said polypeptide and one or more other cellulases for hydrolyzing a lignocellulosic substrate in a sugar-tolerant manner.

  • Publication number: 20190316160
    Abstract: In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, embodiments of the present disclosure, in some aspects, relate to genetically modified Streptomyces bacteria capable of increased thaxtomin production, genetically modified Streptomyces bacteria with reduced activity of a CebR protein encoded by a cebR gene and/or reduced activity of a ?-glucosidase enzyme encoded by the bglC gene, genetically modified Streptomyces bacteria including a mutation of a native cebR gene and/or a native bglC gene, methods of increasing thaxtomin production in Streptomyces bacteria, methods of suppressing CebR and/or BglC activity, methods of producing thaxtomin, and thaxtomin produced by the methods of the present disclosure.

  • Patent number: 9834773
    Abstract: Described are methods and means for metabolic engineering and improved product formation by a filamentous micro-organism or a low G+C gram-positive bacterium. Disclosed is that DasR and DasR binding sites play an important and universal role in the control of gene expression in micro-organisms. Based on this finding, provided are multiple useful applications, such as a method for regulating the expression of a gene of interest, a method for controlling metabolism, a method for decreasing undesired expression and many more. Moreover, provided are means that can be used to establish said methods: for example a micro-organism in which the DasR binding site in operable linkage with a particular gene has been modified to obtain increased or decreased expression of a protein (being a desired or undesired protein) encoded by said gene.
