The present invention provides Bacillus isolates, as well as probiotic and animal feed compositions comprising said isolates, which may be included in the diet of poultry to improve growth performance with reduced energy diets. Methods of using these compositions to improve nutritional uptake or to reduce the incidence of footpad dermatitis in poultry are also provided.

Described herein is a synergistic combination comprising a quorum-sensing inhibitor and/or postbiotic metabolite and an antibiotic. Typically, the postbiotic metabolite comprises at least one peptide. Related compositions, uses, and methods are also described, including methods for resensitizing resistant bacteria to an antibiotic, and methods of treating antibiotic-resistant infections, such as methicillin-resistant Staphylococcus aureus (MRSA).

A method for reducing toxic mercury in wastewater effluent comprises the steps of: identifying a system into which wastewater effluent is introduced, the wastewater effluent including organic compounds and organomercurial compounds; producing a treatment composition comprising a solution including a surfactant, digestive microbes suspended in the solution, and mercury-transformative microbes suspended in the solution; and providing the treatment composition into the system containing the wastewater effluent, such that the digestive microbes degrade the organic compounds in the wastewater effluent, and the mercury-transformative microbes reduce the organomercurial compounds in the wastewater effluent into nontoxic volatile elemental mercury. In certain systems for reducing toxic mercury in wastewater effluent, a biological capture medium is positioned within a vessel and configured to provide a capture point for microbes to adhere to and create biofilms. One such system is a dental evacuation system in which wastewater effluent is introduced into the system via an aspirator.

A biodegradable foam which includes a poly-ester-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 spore germination composition and method to produce a bioaugmentation solution that is added to an anaerobic digester or partially aerobic digester to increase biogas production. A nutrient-germinant composition comprises L-amino acids a phosphate buffer, an industrial preservative, and an optional source of potassium. The composition and spores of one or more Bacillus species are heated to a preferred elevated temperature range of 35° C. to 60° C. for an incubation period of around 20 to 60 minutes to form a bioaugmentation solution that is dispensed to the digester, preferably to the hydrolysis stage of the digester. A dose of bioaugmentation solution is added to the digester around once per day in an amount to provide at least 1000 CFU per mL of the full volume capacity of the digester, which can increase methane production by around 5 to 10% over operation of the digester without the bioaugmentation solution.

The present invention is directed to compositions comprising hydrolase-secreting bacteria and fermenting microorganisms and use thereof, such as for fermentative production of ethanol.

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.

A growth-promoting bacterial agent capable of improving content of soybean oil, preparation method, and use thereof are provided. The growth-promoting bacterial agent is fermented by a DW1 strain, the classification name of the DW1 strain is Bacillus sp., the DW1 strain is deposited in the China Center for Type Culture Collection on Jul. 16, 2021, and the deposit number is CCTCC NO: M 2021889. The growth-promoting bacterial agent of the present disclosure has the ability to dissolve insoluble phosphorus and insoluble potassium and can increase content of readily available phosphorus and readily available potassium in the soil, which has an obvious promoting effect on the growth of soybean and improves soybean yield. The growth-promoting bacterial agent of the present disclosure promotes bacteria and can significantly improve the content of soybean oil. At the same time, it has an affinity of soybean agglutinin and can agglutinate with the soybean agglutinin.

The invention provides environmentally-friendly compositions and methods for reducing the viscosity of crude oil using microorganisms and/or biosurfactants produced by microorganisms.

A composition comprising at least two bacterial strains selected from the group consisting of Bacillus subtilis 281, Bacillus subtilis 3, Bacillus amyloliquefaciens 298 and a functional homolog of any of the preceding, wherein the composition does not comprise more than 5 different species of microbes, wherein: a sample of Bacillus subtilis 281, has been deposited as KCTC 13468BP at the Korean Collection for Type Cultures; a sample of Bacillus subtilis 3, has been deposited as KCTC 13467BP at the Korean Collection for Type Cultures; and a sample of Bacillus amyloliquefaciens 298, has been deposited as KCTC 13469BP at the Korean Collection for Type Cultures. Also provided are methods that utilize the bacterial strains or functional homologs of same.
