  • Publication number: 20050119144
    Abstract: Food processing equipment is cleaned with an aqueous detergent composition wherein the water in the cleaning composition is demineralized. This is combined with concentrated detergent and applied at an elevated temperature to the walls of the food processing equipment. The detergent composition has sufficient sequesterant to remove 100% to 110% of any calcium or magnesium ions released from soil that is removed from the surface of the processing equipment, generally an amount effective to remove from about 10 to about 35 parts per million hardness ions.

  • Patent number: 5616495
    Abstract: Novel Bacillus thuringiensis isolates with hymenopteran activity are described. Also described are toxins having the advantageous hymenopteran activity.This invention further concerns genes or gene fragments which have been cloned from the novel Bacillus thuringiensis isolates which have formicidal activity. These genes or gene fragments can be used to transform suitable hosts for controlling ants.

  • Patent number: 5489432
    Abstract: The subject invention concerns a novel microbe and genes encoding novel toxin proteins with activity against cockroaches. Cockroaches are common house pests, and they create problems in hospitals, the food industry and in agriculture. The novel Bacillus thuringiensis microbe of the invention is referred to as B.t. PS185L8. The subject invention also concerns the use of B.t. PS201T6 to control cockroaches. A truncated form of a toxin obtained from PS201T6 having particular activity to cockroaches is also claimed for use in controlling the pest. The spores or crystals of the two microbes, or mutants thereof, are useful to control cockroaches in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.
