The present invention relates to a species of genus Pseudomonas identified as Pseudomonas BR11571, termed Candidatus Pseudomonas metallosolvens, having Accession Deposit Number DSM 32538.

Methods, compositions, systems and kits relating to processing of cassava bagasse into bacterial feedstock, such as bacterial feedstock suitable for nanocellulose production, are disclosed. Cassava bagasse may be contacted with an acid catalyst or an enzymatic catalyst to produce a hydrolysate, which can be used to form a pre-fermentation medium. Incubation of the pre-fermentation medium with a first population of microorganisms yields a supernatant enriched in reducing sugars, which may be used to form a culture medium which can be used to support growth of a second population of microorganisms to form the nanocellulose.

The present disclosure belongs to the technical field of biological control and prevention, and it was found that Pseudomonasnitroreducens strain HS-18 has good degradation activity on AHLs with C4-C14 chain length, with an efficient and notable degradation effect, providing a new biocontrol agent for prevention and treatment of AHLs-mediated pathogens provides and broadening the quorum quenching species of AHL signaling molecules. By using molecular biology technologies, AHL-quenching genes for HS-18, i.e., the encoding genes aigA and aigC of N-acyl homoserine lactone acyl transferase are cloned. The genes aigA and aigC have broad-spectrum and efficient quenching activities on AHLs with different side chain lengths and different side chain substituents. The expression of aigA and aicC can significantly weaken the motility of AHL-mediated pathogens, the formation of biofilm and the production of virulence factors and significantly weaken the pathogenicity of pathogens to the host plant.

The present disclosure concerns methods of using Pseudomonas chlororaphis subsp. aurantiaca 1214-CHY4 (Accession No. PTA-126941), the cell broth and novel metabolites produced therefrom, that can inhibit the growth of a variety of microbial species for a variety of crops.

Compositions and methods for controlling plant pests and/or improving at least one agronomic trait of interest in a plant are provided. Such compositions and methods comprise a bacterial strain that can be used as an inoculant for plants. Therefore, methods for growing a plant susceptible to a plant pest and/or plant disease caused by a plant pest and methods for controlling plant pests and/or plant disease on a plant susceptible to the plant pest and/or plant disease are also provided.

A recombinant microorganism of the genus Escherichia, comprises a genetic modification that increases expression of a nosZ gene encoding NosZ, which is a nitrous oxide reductase, in the recombinant microorganism, wherein the recombinant microorganism comprises a nosR gene encoding NosR, a nosD gene encoding NosD, a nosF gene encoding NosF, a nosY gene encoding NosY, and an apbE gene encoding ApbE, and wherein the nosR gene, the nosD gene, the nosF gene, the nosY gene and the apbE gene are derived from a microorganism of the genus Pseudomonas, the genus Paracoccus, or a combination thereof.
