  • Patent number: 11793208
    Abstract: Provided herein are methods and compositions for the reduction of microbial contamination of animal carcasses, including fowl, and food products with carbonic acid-based compositions.
    Type: Grant
    Filed: June 15, 2018
    Date of Patent: October 24, 2023
    Assignee: Evonik Operations GmbH
    Inventors: Elena Pisanova, Weidong An, John M. Rovison, Angela Thompson
  • Patent number: 11414329
    Abstract: Provided herein are methods and compositions for reducing the level of a cyanotoxin in cyanotoxin contaminated-water. The electrolytic destruction methods can include contacting the contaminated water with an electrochemical cell in the presence of a magnesium salt and applying an electrical current to the water for a time and in an amount sufficient to oxidize the cyanotoxin. The methods are useful for treatment of lake water, reservoir water, pond water, river water, or irrigation water and any water that serves as a source of drinking water.
    Type: Grant

  • Patent number: 11122802
    Abstract: The present invention relates to compositions and formulations for soil disinfection against a wide spectrum of plant pathogens and pests. More particularly, the formulation comprising (i) peracids, such as peracetic acid and an GO anionic surfactant, such as capryleth-9 carboxylic acid is synergistically effective in treatment of soil to control plant parasitic nematodes and soil-borne plant pathogens such as bacteria, spores and fungi.

  • Publication number: 20200238887
    Abstract: A trailer for transporting a liquid mixture having at least about 5% peracetic acid by weight includes a stainless steel tank having an external spill containment enclosure and a predetermined maximum allowable working pressure. One or more pressure relief valves are included in a wall of the tank within the external spill containment enclosure and configured to provide pressure relief to the tank at a pressure of between about 20%-50% of the maximum working pressure of the tank, thereby preventing over-pressurization of a reactive and decomposing fluid during a fire event. Wheels and a kingpin are affixed to the tank to enable transportation over public roadways.

  • Publication number: 20180271090
    Abstract: A method of sterilizing a material, said method comprising the steps of: a) providing a sterilizing composition comprising (i) peracetic acid and (ii) a stabilizer selected from the group consisting of citric acid, isocitric acid, aconitic acid and propane-1,2,3-tricarboxylic acid; b) introducing such sterilizing composition into a hot gaseous stream to produce a peracetic acid vapor; and c) contacting such peracetic acid vapor with the material to be sterilized. The use of such an organic acid stabilizer results in an unexpected reduction in the amount of residue deposited on the heating surface employed to vaporize the sterilizing composition.
