The present invention provides recombinant microorganisms comprising an isobutanol producing metabolic pathway and methods of using said recombinant microorganisms to produce isobutanol. In various aspects of the invention, the recombinant microorganisms may comprise a modification resulting in the reduction of pyruvate decarboxylase and/or glycerol-3-phosphate dehydrogenase activity. In various embodiments described herein, the recombinant microorganisms may be microorganisms of the Saccharomyces clade, Crabtree-negative yeast microorganisms, Crabtree-positive yeast microorganisms, post-WGD (whole genome duplication) yeast microorganisms, pre-WGD (whole genome duplication) yeast microorganisms, and non-fermenting yeast microorganisms.

Yeast and a yeast extract with a high content of Abu, -Glu-Abu, and/or -Glu-Abu-Gly are provided. By modifying yeast so that intracellular acetolactate synthase activity is reduced, yeast with a high content of Abu, -Glu-Abu, and/or -Glu-Abu-Gly is obtained. An yeast extract is prepared by using the yeast obtained in such a manner as a raw material.

The present invention relates to a method for managing flea beetles from the family of Chrysomelidae in Brassica crops. The invention further relates to seed and a kit of parts for use in this method. The invention also relates to the use of Bacillus amyloliquefaciens ssp. plantarum MBI600 for managing flea beetles in Brassica crops.

The present disclosure relates to a novel acetohydroxy acid synthase (AHAS) variant improving L-isoleucine producing ability, a microorganism including the same, and a method of producing L-isoleucine using the microorganism.

The present disclosure relates to a recombinant microorganism capable of efficiently producing L-leucine and an L-leucine production method using the same. The production method includes: (p) incubating a recombinant microorganism having an L-leucine biosynthesis pathway or a processed product of microbial cells thereof in a predetermined culture medium (X) to thereby produce L-leucine; and (q) recovering a fraction including the L-leucine from the predetermined culture medium (X). The recombinant microorganism includes, in an expressible form, a gene encoding an amino acid dehydrogenase. The amino acid dehydrogenase at least has a catalytic effect on an L-leucine production reaction in the L-leucine biosynthesis pathway.

Multi-carbon compounds such as ethanol, n-butanol, sec-butanol, isobutanol, tert-butanol, fatty (or aliphatic long chain) alcohols, fatty acid methyl esters, 2,3-butanediol and the like, are important industrial commodity chemicals with a variety of applications. The present invention provides metabolically engineered host microorganisms which metabolize methane (CH.sub.4) as their sole carbon source to produce multi-carbon compounds for use in fuels (e.g., bio-fuel, bio-diesel) and bio-based chemicals. Furthermore, use of the metabolically engineered host microorganisms of the invention (which utilize methane as the sole carbon source) mitigate current industry practices and methods of producing multi-carbon compounds from petroleum or petroleum-derived feedstocks, and ameliorate much of the ongoing depletion of arable food source farmland currently being diverted to grow bio-fuel feedstocks, and as such, improve the environmental footprint of future bio-fuel, bio-diesel and bio-based chemical compositions.

Compounds, compositions, and methods for controlling the level of a target protein in a cell are described. Compounds of the disclosure include those having according to the formula PTM-L-LTM, wherein PTM is a targeting moiety that binds the target protein, L is a covalent bond or linker moiety, and LTM is a ubiquitin ligase binding moiety that binds a plant ubiquitin ligase. Additionally novel cereblon binding moieties are provided that may be used as molecular glues or in bifunctional compounds to target proteins in plants and mammals.

The present invention relates to a recombinant microorganism for producing 1,3-propanediol, wherein a pathway converting pyruvate into 2,3-butanediol is inhibited in a microorganism having a pyruvate and acetyl CoA biosynthetic pathway. In addition, the present invention relates to a method for producing 1,3-propanediol by using the recombinant microorganism.
