Abstract
An enzyme formulation includes an encapsulated fungal enzyme which is effective for degrading at least one material selected from the group consisting of hydrocarbons, vulcanized rubber, synthetic rubber, natural rubber, vulcanized polymers and perfluorinated compounds. A degradation method includes treating one of the above-mentioned materials with an encapsulated fungal enzyme to degrade the material.
Claims11
An encapsulated fungal enzyme composition in the form of beads, comprising:
- an extracellular enzyme suite comprising at least two enzymes selected from manganese peroxidase, lignin peroxidase, or laccase;
- and further comprising Mn2+ ions or a peroxide;
- and
- wherein the extracellular enzyme suite is encapsulated within a shell, wherein the shell comprises a first layer and a second layer, wherein the first layer is interfaced with the extracellular enzyme suite and wherein the first layer comprises a cross-linked hydrogel;
- and wherein the second layer is interfaced with the first layer and wherein the second layer comprises poly(lauryl methacrylate), poly(stearyl methacrylate), poly(isoprene), or poly(butadiene).
