Abstract: A microbiological method of desulfurization (MDS) of hydrocarbon fuels such as coal, coal tar and petroleum uses an aqueous microbial biocatalytic agent which is not significantly reproducing but is still capable of oxidizing inorganic sulfur compounds and/or of selectively cleaving sulfur-carbon bonds in organic compounds, thereby removing sulfur with insignificant losses in fuel value. Microorganisms are selected according to the type of fuel sulfur present and the environment in which the desulfurizing process is to take place. One embodiment allows droplets of highly concentrated cell-water suspensions to pass from the top surface of the fuel through to the bottom, desulfurizing along the way and removing the sulfur products of the process as well. This MDS method can be used during hydrocarbon fuel production, storage, transport, and/or processing conditions, thereby also providing an added benefit in corrosion protection of the vessels used for these functions.

Abstract: The present invention is directed to a method for the disinfection and sterilization of material and surfaces contaminated with one or more members selected from the group consisting of bacteria and bacterial spores, comprising the steps of: (a) providing a biocidal fluid containing a mixture of effective amounts of a germinant and a germicide; and (b) contacting the material and surfaces contaminated with one or more members selected from the group consisting of bacteria and bacterial spores, with the biocidal fluid of step (a) for a time sufficient for disinfecting and sterilizing said material. The invention also provides a sterilizing composition suitable for killing and rendering spores lifeless comprising: (a) an effective amount of a germinating agent; (b) an effective amount of a germicide.

Abstract: A composition of matter for repelling animals comprising the mixture of a metallic metal, a quantity of a soil that has been extracted from the earth, a nutrient source, and water. The soil is the type having a plurality of metallic metal metabolizing organisms thriving therein. The metallic metal is an ionic form of selenium. The nutrient source is a carbohydrate. In particular, the nutrient source can be lactose. The composition of matter further comprises a nitrogen source, such as tryptone. The composition may also include a quantity of tetrahydrofloate.

Abstract: Animal tissue is trypsinized to form a cell suspension which is placed in a nutrient medium with a virus. Produced interferon is centrifugally separated, acidified and stored at a low temperature to inactivate the virus. It may then be frozen until it is prepared for use.
