Also provided are a polynucleotide molecule encoding the mutant, a nucleic acid construct and a host cell comprising the polynucleotide molecule, a composition comprising the mutant, and the use of the mutant, the polynucleotide molecule, the nucleic acid construct and the host cell.

Materials and methods for controlling limitation conditions in product biosynthesis for non-PHB generating species of the genera <i>Ralstonia </i>or <i>Cupriavidus </i>and organisms related thereto

Provided herein are methods for increasing the yield of an extracellular product synthesized by an organism cultured in a continuous aerobic fermentation system. The extracellular product yield is increased through the use of an organism modified to decreased production of polyhydroxyalkanoate, to increase production of the extracellular product, and to include promoters that can be inducible in response to nutrient limitation conditions. The extracellular product yield is also increased by operating the continuous fermentation system under particular nutrient limitation conditions. Also provided are non-naturally occurring organisms that have been modified for use with the provided methods, and extracellular products made using the provided methods.

MATERIALS AND METHODS FOR IDENTIFYING AND USING YEAST STRAINS THAT METABOLIZE PENTOSE SUGARS IN THE PRESENCE OF D-GLUCOSE
20180334649 · 2018-11-22 ·

Disclosed herein are materials and methods for creating and/or isolating variants of yeasts especially variants of Saccharomyces cerevisiae that can grow on sugars other than D-glucose in the presence of amounts of 2-deoxy-glucose and or D-glucose that inhibit most strains of yeast from growing on sugars other than D-glucose. Selection media that can be used to isolate such variants include pentose sugars such as D-xylose, L-glutamine and 2-deoxy-glucose. Mutations in the Grr1 and Red genes in some strains also produce variants that can grow on sugars including the pentose D-xylose in the presence of 2-deoxy-glucose.
