It has been discovered that the desert endophytic bacterium SA187 SA187 can provide resistance or tolerance to abiotic stress conditions to seeds or plants. Compositions containing SA187 can be used to enhance plant development and yield under environmental stress conditions.

The present invention relates to methods of improving the environment within a poultry farming facility including reducing ammonia production in a poultry facility, inhibiting urease enzymes in poultry litter, reducing levels of pathogenic bacteria in poultry litter, improving productivity of poultry farms, reducing or preventing pododermatitis in poultry reared in mass production poultry facilities and controlling pests in poultry litter. Compositions, suitable for use in such methods, comprising at least one microorganism of the genus Bacillus and at least one biosurfactant wherein the biosurfactant is present in an amount of 2 mg/L to 7000 mg/L are also described.

Described herein are genes involved in Firmicutes exopolysaccharide production. Also described are mutations to those genes and corresponding mutated proteins to increase or stabilise exopolysaccharide production or prevent exopolysaccharide autodegradation, in particular over the course of a fermentation. Further described herein are fermentation methods and uses of the mutated genes and proteins, and of the microorganisms and the exopolysaccharides.

The subject of the present invention is a novel Paenibacillus polymyxa B134 strain, PCM deposit no. B/00335, deposited in the Polish Collection of Microorganisms of the Polish Academy of Sciences in Wroclaw, and the use thereof in plant cultivation, for use against fungal pathogens and for biostimulation of plant growth and development.

The present disclosure relates to a microorganism producing O-acetylhomoserine with high efficiency and a method for producing O-acetylhomoserine and L-methionine using the microorganism. The present disclosure provides a microorganism producing O-acetylhomoserine having an enhanced activity of a protein which is predicted to export O-acetylhomoserine, and a method for producing O-acetylhomoserine and L-methionine using the microorganism.

A method for organically planting Dendrobium, including using a planting medium in the epiphytic planting step of Dendrobium. The raw materials of planting medium include fermented powder of Dendrobium candidum leaves and sawdust; a method for preparing the fermented powder of Dendrobium candidum leaves is as follows: cutting Dendrobium candidum leaves into small pieces and mashing the small pieces of Dendrobium candidum leaves to obtain materials to be fermented, and then adding liquid medium to the materials to be fermented to obtain fermentation system; sterilizing the fermentation system, adding fermentation bacteria to the fermentation system to obtain a mixture, fermenting and filtering the mixture to obtain post-culturing fermentation broth and fermented products of Dendrobium candidum leaves, dewatering and crushing the fermented products of Dendrobium candidum leaves to obtain fermented powder of Dendrobium candidum leaves.

The disclosure relates to genetically modified microorganisms of the genus Bacillus, for the improvement of phenotypes of plants, for example nitrogen availability for non-leguminous plants. Included are 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 species, for example nitrogen fixation, utilization, regulation, uptake, acquisition, tolerance, and/or processing in plants.
