  • Publication number: 20220248689
    Abstract: Storage-stable compositions for generating antimicrobial activity are described. The compositions comprise an enzyme that is able to convert a substrate to release hydrogen peroxide, and an unrefined natural substance, such as a honey, that includes a substrate for the enzyme. In certain embodiments, the enzyme is a purified enzyme. In other embodiments, the substrate lacks catalase activity, and 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. The storage-stable compositions do not include sufficient free water to allow the enzyme to convert the substrate. Use of the compositions to treat microbial infections and wounds is described, as well as methods for their production.

  • 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.
