NOVELTY - An isolated, biologically pure Bacillus subtilis strain, which is deposited under American Type Culture Collection with a patent deposit designation number PTA-7736 (ATCC PTA-7736) is new.    USE - For preventing or treating condition or diseases resulting from the presence or overgrowth of unwanted organisms such as algae or fungi in, on, or surrounding of a sample (where sample is a subject which has propensity to allow the presence or overgrowth of unwanted organism in, on or surrounding the subject) e.g. liquid (water such as water in a lake, a river, a canal, a pond, a tank, or a reservoir), gas such as air (atmosphere, the processed air, or the air confined in a close container or space (e.g., the air in a building or a car), solid matter such as soil, life form such as plant, human or animal (plant includes tree, flower, leaf, trunk, branch, fruit, root, vegetable, herb, fern, and moss) or a tangible article (e.g. residential building, commercial building, construction, boat, toy, vehicle, piece of furniture, piece of art, book, and food); for treating condition of a plant e.g. soil-related plant disease (e.g. Phytophthora, Pythium, Verticillium, Rhizoctonia, or Fusarium), a foliar disease (e.g. Botrytis, Collectotrichum, Mycosphaella, Septoria, Fusarium, Powdery Mildew, or Downy Mildew), a flower disease (e.g. Botrytis Blight), or a post-harvest disease (e.g. Penicillium, Geotdchum, or Botrytis); for treating condition of a human or an animal e.g. allergy to the fungi articles or fungal infections of respiration system, genitourinary system, bone, eye, nail, hair or skin (claimed); for preventing, controlling, alleviating or treating a diseases resulting from the presence or overgrowth of unwanted organisms e.g. weeds; mould.    ADVANTAGE - The method effectively controls, treats, regulates, modulates, alleviates, reduces, prevents or cleanses condition, resulting from the presence or overgrowth of unwanted organisms, of a sample by delivering the compositions to a sample. The composition can be delivered uniformly and/or efficiently, and it improves the water quality in water. The composition prevents the presence or overgrowth of fungi or mold in the air. The composition cleans the samples of unwanted elements or organisms (e.g. the presence or overgrowth of algae or fungi). In addition to forming a thin uniformly distributed film over the water surface, the microbial agents can be released into the body of water and move downward through the primary regions where the target pests or diseases are located during and after surface distribution. The hydrophobic compositions effectively treats and improves water quality by controlling algae growth, de-odorizing the water application, suppressing water eutrophication, and reducing total suspended solids, ammonia, free nitrates and phosphates in water. During treatment of the aquarium or fish tank for algae growth, the fish and any other aquatic/marine life forms does not need to be removed from the aquarium or fish tank. The microbial agents and hydrophobic carriers of the hydrophobic composition are not harmful to aquatic/marine life or wildlife, unlike other methods that employ chemicals or pesticides. The methods that employ microbial agents are environmentally safe.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preventing or treating a condition of a sample involving applying a composition comprising an isolated Bacillus subtilis strain ATCC PTA-7736 to the sample.
