This disclosure describes recombinant Megasphaera microbes designed to include increased consumption of acetate, increased carbon flux to butyryl-CoA and/or hexanoyl-CoA, increased production of butyrate and/or hexanoate, or a combination thereof, than a comparable control. This disclosure also describes methods that generally include growing such recombinant microbes under conditions effective for the recombinant microbes to consume greater amounts of acetate, produce increased amounts of butyryl-CoA and/or hexanoyl-CoA, produce increased amounts of butyrate and/or hexanoate, or a combination thereof.

Soil plant productivity is improved by manipulation of soil microflora. The soil microflora is manipulated by addition of a bacterium belonging to Rhizobium (Rhizobiales) to the soil.

The invention relates to a process for the recovery of CO.sub.2 by biological reduction comprising a step of bringing a liquid phase containing the bacterium Stenotrophomonas maltophilia into contact with a CO.sub.2-containing gas phase under conditions allowing the production of formate and/or methane from said CO.sub.2. The process according to the invention can be implemented in particular in a closed reactor or a semi-closed reactor or a continuous reactor, electrochemically assisted or not.

The present invention relates to a method including culturing a C.sub.1 compound-assimilating bacterium, which is a methylotroph, and/or a yeast by using a medium comprising, for example, a C.sub.1 compound and/or glycerol as a carbon source, to thereby produce EGT.

The disclosure relates to isolated microorganisms—including novel strains of the microorganisms—microbial consortia, and agricultural compositions comprising the same. Furthermore, the disclosure teaches methods of utilizing the described microorganisms, microbial consortia, and agricultural compositions comprising the same, in methods for imparting beneficial properties to target plant species. In particular aspects, the disclosure provides methods of increasing desirable plant traits in agronomically important crop species.

Disclosed herein are methods and compositions of matter that enable the biological conversion of gaseous waste streams (CO.sub.2, stranded natural gas, flue gas, biogas, landfill gas, etc.) to a platform chemical, 3-hydroxybutyrate, which can in turn be upgraded to fuels and polymers (e.g. polypropylene and polymers). The technology thus presents both a mechanism to valorize gaseous waste streams and establish sustainable production routes to chemicals and plastics via the overexpression of PHB depolymerase while knocking out the AACS pathway in this specific strain of methanotrophic bacteria.

Disclosed herein is an isolated strain of Roseburia hominis HGM001, which is deposited at Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH under an accession number DSM 34119. A method for producing butyric acid using the isolated strain of Roseburia hominis HGM001, a fermented culture produced by the method, and a method for alleviating an inflammatory disorder using the fermented culture are also disclosed.

The disclosure discloses Lactococcus lactis subsp. lactis CCFM1018 and application thereof in preparation of food and medicine for excreting a plasticizer, and belongs to the technical field of microorganisms. The Lactococcus lactis subsp. lactis CCFM1018 not only is significantly better than the intestinal resident bacteria Escherichia coli and Enterococcus faecalis in terms of the effect of promoting the excretion of DEHP and MEHP, but also is better than the commercial strain Lactobacillus rhamnosus LGG. Therefore, the Lactococcus lactis subsp. lactis CCFM1018 of the disclosure can be used as an effective means to prevent and alleviate body damage caused by DEHP and MEHP, and does not have toxic or side effects of drugs. Lactococcus lactis subsp. lactis CCFM1018 can be used to prepare pharmaceutical compositions and fermented food for alleviating and preventing the toxicity of DEHP and metabolites thereof, and has a very broad application prospect.

The present invention relates to the preventive or curative treatment of metabolic syndrome and associated disorders, and inflammatory bowel diseases using Coprococcus bacteria and/or culture supernatants thereof.

Provided is a method for disposing of contaminated deposit soil and recycled reclamation soil using the same and, more specifically, a method for disposing of contaminated dredged soil, the method comprising the steps of: seeding a mixed strain NIX51 (KACC81038BP) in the contaminated dredged soil to primarily dispose of contaminated materials in a bioreactor; and washing the degraded soil, which has been primarily disposed of, with a washing solution containing at least one selected from the group consisting of citric acid, oxalate, carbonic acid (H.sub.2CO.sub.3), and nitric acid, to secondarily dispose of heavy metals.
