The present disclosure describes the engineering of microbial cells for fermentative production of 2-oxoadipate and provides novel engineered microbial cells and cultures, as well as related 2-oxoadipate production methods.

Described are strains and methods relating to genetically-engineered yeast cells that overproduce lysine in a tunable manner by altering feedback inhibition of the lysine synthetic pathway by way of the LYS20 and LYS21 homocitrate synthase polypeptides. The yeast can be used in a conventional bioethanol production facility to produce alcohol along with increased amounts of lysine, resulting in increased quality and commercial value of fermentation products and co-products, such as animal feed ingredients.

The present invention relates to methods and means for producing nitrogenase polypeptides in the mitochondria of plant cells.

The description provides, inter alia, recombinant microorganisms, engineered metabolic pathways, chemical catalysts, and products produced through the use of the described methods and materials. The products produced include functionalized alpha substituted C4 dicarboxylic acids and functionalized acrylic acids and salts, esters and lactones thereof.

This document describes biochemical pathways for producing pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine or 1,7-heptanediol by forming one or two terminal functional groups, each comprised of carboxyl, amine or hydroxyl group, in a C7 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on the C1 elongation enzymes or homolog associated with coenzyme B biosynthesis.

The present disclosure provides guided microbial remodeling (GMR) methods for the rational improvement of plant-associated microbes to perform plant-beneficial functions. The GMR methods described herein allow for non-intergeneric genetic optimization of key regulatory networks within the microbes, which improve plant-beneficial functions over wild-type microbes but don't have the risks associated with transgenic approaches (e.g., unpredictable gene function, public and regulatory concerns, etc.). The present disclosure also provides remodeled microbes and compositions thereof. The utilization of remodeled microbes and compositions thereof will enable farmers to realize more productive and predictable crop yields without the nutrient degradation, leaching, or toxic runoff associated with traditional synthetically derived fertilizers.
