The present invention provides a Paracoccus aminovorans BM109 strain (Accession number KCTC 15059BP) having excellent removal of trimethylamine (TMA) or trimethylamine N-oxide (TMAO), and a pharmaceutical composition for preventing or treating diseases caused by TMA or TMAO, a health functional food composition for preventing or improving diseases caused by TMA or TMAO, and a feed composition for preventing or improving diseases caused by TMA or TMAO, including the strain as an active ingredient.

The present invention relates to a recombinant microbial cell for producing at least one compound having structural Formula III from at least one simple carbon source:

##STR00001## wherein the simple carbon source is selected from the group consisting of glucose, sucrose, xylose, arabinose, mannose and glycerol; and wherein the cell comprises a further genetic modification to increase production of L-lysine in the cell from at least one of the simple carbon sources.

Disclosed are methods and apparatuses utilizing an O.sub.2-insensitive FDH2 from the sulfate-reducing bacterium (SRB) Desulfovibrio vulgaris Hildenborough (DvH). The O.sub.2-insensitive FDH2 may be applied to a biofuel cell for generating electricity and generating hydrogen peroxide. The biofuel cell can also be applied to wearable or implantable devices as a power source. The O.sub.2-insensitive FDH2 can also be used in other applications not applying a fuel cell, such as hydrogen peroxide generation, a formate testing kit, or carbon capture applications.

Recombinant microorganisms that catabolize lignin aromatics, such as -5 linked lignin aromatics, and methods of using same to catabolize the lignin aromatics.

The present disclosure relates to a variant polypeptide having attenuated dihydrodipicolinate reductase activity and a method of producing L-threonine using the same.

Disclosed is a novel genetically modified microorganism showing improved yields of 3-hydroxyadipic acid and/or -hydromuconic acid. The genetically modified microorganism is a microorganism having an ability to produce 3-hydroxyadipic acid and/or -hydromuconic acid, in which the reaction to generate malic acid from oxaloacetic acid is enhanced, and the reaction to generate acetyl-CoA from pyruvic acid is enhanced. In addition, the reaction to generate carbon dioxide from formic acid is enhanced.

The present disclosure relates to a modified polypeptide, in which the activity of meso-diaminopimelate is weakened, and a method for producing L-threonine using the same.

An engineered yeast strain capable of efficient fermentation of xylose to ethanol, and methods of making and using the strain, are provided.
