Compositions comprising microbiological strains and cultures and methods of use thereof are provided herein. Certain strains, cultures, and compositions thereof are useful for the control of head blight disease, for example, of various crop plants. Biological control compositions, and methods of use thereof to prevent, inhibit or treat the development of plant pathogens or disease and for preserving plant yield, are also provided.

The present invention relates to an animal feed or an animal feed additive comprising Bacillus strains which improve the health and performance of production animals, and the use of such.

The disclosure provides a method of treating, preventing, and/or controlling plant diseases by applying the agricultural composition comprising a bacterial isolate belonging to Paenibacillus or Bacillus. Also, the disclosure provides a method of enhancing disease resistance of a plant seed by applying the agricultural composition to the plant seed, and an agricultural composition comprising the bacterial isolate.

A method for treating wastewater and an activator for treating wastewater that maximizes the utilization of microorganisms such as Bacillus bacteria in an activated sludge treatment of wastewater while minimizing treatment cost. In the method for treating wastewater, wastewater including organic matter is introduced into a treatment tank and the wastewater is subjected to an activated sludge treatment by microorganisms in the treatment tank, wherein an activator containing a component for activating the microorganisms is added to the wastewater to be subjected to the activated sludge treatment in the treatment tank; and at least 50% (by quantity) of the entirety of the activator has a particle size of less than 10 pm. Also provided is an activator therefor. The microorganisms preferably include Bacillus bacteria.

A Bacillus strain characterized by (i): sensitivity for ampicillin, vancomycin, gentamicin, kanamycin, streptomycin, erythromycin, clindamycin, tetracycline and chloramphenicol; (ii) antimicrobial activity against E. coli and Clostridium perfringens; and (iii) a sporulation percentage of at least 80 when measured after 2 days of incubation. The invention further relates to a method for selecting such strains. Many of the identified strains according to the invention are of the species Bacillus amyloliquefaciens. Some of the Bacillus amyloliquefaciens were further identified as Bacillus amyloliquefaciens subsp. amyloliquefaciens whereas others were identified as amyloliquefaciens subsp. plantarum. A Bacillus strain of the invention may be used as a feed additive to animal feed where it has a probiotic effect.

The proposed solution refers to agricultural biotechnology and microbiology. It represents Bacillus mojavensis PS17 strain that was isolated from the seeds of the Sadokat variety of spring wheat and was deposited in the National Bioresource Center - Russian National Collection of Industrial Microorganisms (NBC VKPM), NRC “Kurchatov Institute” - GosNIIgenetika under registration number VKPM B-13415. The strain has a broad spectrum of activity against plant pathogenic fungi and improves the yield of agricultural crops. The strain is non-toxic to animals, exhibits growth-stimulating activity for plants and can be used to produce of biopreparations on the basis thereof for the protection of plants from diseases caused by fungal pathogens.

A biodegradable foam which includes a polyester-based polyurethane foam and a mixture comprised of a soil-dwelling carbon-digesting bacteria embedded in a carrier compound. The mixture of the soil-dwelling carbon-digesting bacteria is homogenously dispersed throughout the polyester-based polyurethane foam. This biodegradable foam exhibits biodegradation rates higher than a polyester-based polyurethane foam absent the soil-dwelling carbon-digesting bacteria.

A soil-borne plant disease control agent that can be safely used as a biopesticide. The active component of the control agent includes viable bacteria of novel strains of Bacillus and Fictibacillus, or a culture of these bacteria. The soil-borne plant disease control agent is a vegetable wilt control agent. The plant disease control agent can be applied (sprayed) to stems and leaves to control a bacterial wilt disease caused by soil bacteria Ralstonia solanacearum species complex, and/or bacterial soft rots. A plant disease control method.

Compositions and methods are provided for producing silage additive composition for producing silage and for controlling pests that infect silage and stored grains. The silage additive composition comprises a microbial inoculant and diatomaceous earth, wherein the microbial inoculant comprises one or more strains of bacteria, wherein the at least one of one or more strains bacteria is capable of producing lactic acid.

The present invention refers to a process designed to increase the production of plant growth-promoting microorganisms of the Bacillus genus, using a culture medium poor in nutrients and with specific environmental conditions, allowing to obtain a greater amount of biomass and/or spores, which can be used to prepare solid or liquid compositions to be applied to plants, aiming to promote their growth and/or counteract the effect of phytopathogenic agents.
