  • ANTIMICROBIAL FIBERS AND COMPOSITIONS
    Publication number: 20200323963
    Abstract: Fibers for generating antimicrobial activity are described. The fibers comprise an enzyme that is able to convert a substrate to release hydrogen peroxide, and a substance that includes a substrate for the enzyme. In the presence of sufficient free water, the enzyme converts the substrate to release hydrogen peroxide, which is effective against a wide range of microbes. Wound dressings and compositions for forming such fibers are also described, as is the use of the fibers, wound dressings and compositions.
    Type: Application

  • ANTIMICROBIAL FIBERS AND COMPOSITIONS
    Publication number: 20180023217
    Abstract: Fibers for generating antimicrobial activity are described. The fibers comprise an enzyme that is able to convert a substrate to release hydrogen peroxide, and an unrefined natural substance that includes a substrate for the enzyme, wherein the enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the unrefined natural substance. In the presence of sufficient free water, the enzyme converts the substrate to release hydrogen peroxide, which is effective against a wide range of microbes. Wound dressings and compositions comprising the fibers are also described, as is use of the fibers, wound dressings and compositions, particularly for wound healing.

  • PREVENTION AND TREATMENT OF MICROBIAL INFECTIONS
    Publication number: 20170266240
    Abstract: Compositions for prevention and treatment of microbial infectious, such as microbial infections that comprise a biofilm, or a microbe that is capable of forming a biofilm are described. The compositions comprise an enzyme that is able to convert a substrate to release hydrogen peroxide and a substance that includes a substrate for the enzyme. The enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the substance. The substance may be an unrefined natural substance or a substance that includes a purified substrate for the enzyme.
