A method of reducing a concentration of N.sub.2O, NO, or a combination thereof in a medium, the method comprising: culturing a microorganism of the genus Paracoccus, a microorganism of the genus Pseudomonas, or a combination thereof in a liquid medium comprising Mg.sup.2+ ions and Fe(II)(L)-NO, N.sub.2O, or a combination thereof, wherein L is a chelating agent; and reducing NO to N.sub.2O or N.sub.2, or reducing N.sub.2O to N.sub.2.

This disclosure provides a genetically-modified bacterium from the genus Pseudomonas that comprises an exogenous nucleic acid encoding an enoyl-CoA reductase and an exogenous nucleic acid encoding an acyl-CoA reductase that produces medium chain length alcohols. The disclosure further provides methods for producing medium chain alcohols using such genetically-modified bacterium. This disclosure provides a renewable, bio-based production platform for valuable mcl-alcohols that have a wide range of industrial applications. Current production of mcl-alcohols typically occurs through the hydrogenation of plant oils and waxes. This process leads to issues of deforestation and is largely unsustainable. Utilizing waste lignin streams as the carbon source provides a more sustainable feedstock that can be generated from plant waste like corn stover. Along with this, the use of lignin avoids competition with food resources as traditional starch and sugar feedstocks.

The present invention relates to a new isolated strain of Pseudomonas sp. deposited at the “Colección Española de Cultivos Tipo” (CECT) under the accession number CECT8708 or a mutant thereof; wherein said mutant is obtained using the CECT8708 of Pseudomonas sp. as starting material, maintains the dual bactericidal and fungicidal effects of CECT8708 and has a genome with an Average Nucleotide Identity (ANI) to the genome sequence SEQ ID NO: 1 of at least 99.8%. The strain of the invention has bactericidal and fungicidal effect.

The invention also relates to the inoculation product comprising the strain of the invention, the cell-free extract derived from the strain of the invention, and the composition comprising it and their uses in the control of bacteria and/or fungal infection in a plant. Also refers to a method to obtain the mutant strain of the strain of the invention.

A Pseudomonas graminis strain capable of degrading cellulose at a low temperature and use thereof. The accession number of the Pseudomonas graminis strain is CGMCC NO.: 18751. The strain has relatively strong capability of degrading cellulose at both a low temperature of 4° C. and a condition of 10° C., and the cellulose degradation capacities are basically the same. Although the cellulose degradation capacity is weakened at 30° C., the degradation amplitude is not large, and meanwhile, a KY240 strain also has potassium and inorganicphosphorus degradation capacity, and is expected to be used for preparing a bacterial fertilizer for degrading cellulose, promoting straw decomposition and improving soil fertility, particularly improving the amount of potassium and phosphorus available for plants in soil.

The subject invention provides methods for improving the treatment of effluents and waste matter produced during food processing and production. In particular, the subject invention provides methods for remediating fats, oils and greases (FOG), suspended solids, proteins, and other organic matter that are discharged from plants that process, for example, meats, poultry, seafood, dairy and plant-based oils. The methods of the subject invention utilize a customized microbial cocktail comprising facultative anaerobes, in combination with one or more microbial growth by-products, e.g., enzymes and/or biosurfactants, to digest and/or liquefy food processing waste matter.

The present disclosure relates to a genetically modified microbial cell that includes a first genetic modification resulting in the expression of an exogenous vanillate demethylase, such that the microbial cell is capable of metabolizing an S-lignin decomposition product and producing 2-pyrone-4,6-dicarboxylate (PDC).
