  • Patent number: 6268189
    Abstract: A fungal Ldh protein and a gene have been isolated from Rhizopus oryzae. Host organisms transformed with expression vectors containing this gene produce optically pure, or enhanced levels of L-(+)-lactic acid not characteristic of the wild type organisms. These transformants will be useful for providing an increased supply of lactic acid for use in food and industrial applications.

  • Patent number: 6261790
    Abstract: Methods to detect prion or PrP-Sc protein as an indication of transmissible spongiform encephalopathies (TSEs) are described. In one aspect, the invention is directed to monoclonal antibodies that specifically bind a conserved epitope of prion proteins and use of the antibodies in immunoassays to detect PrP-Sc, in fixed or unfixed tissue, as an indication of the presence of TSE infection. In another aspect, the invention is directed to a monoclonal antibody cocktail having the monoclonal antibody in combination with a second monoclonal antibody which specifically binds to a second conserved epitope of prion proteins. One or both monoclonal antibodies of the cocktail can recognize epitopes found in all mammalian species in which a natural TSE has been reported and in a number of closely related species.

  • Patent number: 6258391
    Abstract: In the manufacture of hard cheese, cheese milk is treated with high pressure CO2 to accelerate the precipitation of casein and thereby promote the rapid formation of curd. Curd can be produced by this process in a period of a few minutes without adverse affects on the rennet or starter culture. The high pressure CO2 treatment of cheese milk can substantially increase the daily curd yields and plant throughput, thereby significantly reducing processing costs.

  • Patent number: 6245294
    Abstract: The killing of microorganisms on the surface of porous and non-porous materials including agricultural commodities is accomplished by use of methods and apparatus which expose the material to controlled applications of a biocidal treatment gas into a sub-atmospheric environment. The material is first exposed to a vacuum then, without an intervening flush step, full treated with an air-free treatment gas prior to being re-exposed to a vacuum. The method and apparatus successfully kill microorganisms both on the surface and within the pores or structural recesses of the material without causing significant deleterious changes to the material.

  • Patent number: 6232880
    Abstract: A device worn externally (or parts of which may be inserted in the ear canal) by an animal which uses a programmable repertoire of bilaterally applied aversive stimuli for the autonomous control of an animal's location and direction of movement is disclosed. Electromagnetic signals and electromechanical hardware are activated through a dedicated, embedded computer system, that allows a cascade of one or more aversive stimuli, normally acoustic and/or electrical stimulation, to be bilaterally applied to either the right or left side of an animal as a cue to change its location through a specific direction of movement. Aversive stimuli are programmed to be administered only when an animal penetrates a predetermined boundary. The embedded computer uses satellite position system data to determine the animal's location with respect to the closest boundary line and then calculates when and to which side of the animal the repertoire of bilateral aversive stimuli is to be applied.

  • Patent number: 6228355
    Abstract: The invention provides a method and compositions for controlling food borne enteric bacterial pathogens in poultry populations. The incidence of the colonization of poultry by enteropathogenic bacteria, and/or the populations of enteropathogenic bacteria within colonized poultry, may by substantially reduced by providing particles of an expanded matrix material to the locus or vicinity of the animals, particularly during the period of feed removal prior to slaughter. The method and compositions are particularly useful for the control of Salmonella species, enteropathogenic Escherichia coli, and Campylobacter species.

  • Patent number: 6224921
    Abstract: Low oil uptake frying batters substantially based on rice flour have been developed that maintain desirable organoleptic properties while significantly reducing fat absorption during the frying process. This is accomplished by inclusion of cold water swelling rice-based starch products selected from the group consisting of pregelatinized rice flour, phosphorylated rice starch and pregelatinized acetylated rice starch into the rice starch batter compositions.

  • Patent number: 6223463
    Abstract: The system and method for preventing the passage of crawling insects upon the exterior surface of an object includes a member having an inner surface, adapted to be disposed adjacent to the exterior surface of the object, an opposed outer surface that has a low coefficient of friction for preventing the insects from traversing the outer surface since the crawling insects are unable to obtain sufficient traction with the outer surface of the member, a means for affixing the member to the exterior surface of the object so that the insects are forced to attempt to traverse the outer surface of the member in order to reach the exterior surface of the object above the member.
