Claims23
A composition comprising:
- at least one nanoparticle, wherein the nanoparticle comprises one or more of a cuprous oxide, a hydroxyapatite, magnesium chloride, manganese chloride, calcium chloride, zinc, magnesium, manganese, or a combination thereof;
- and
- at least one psychrophilic enzyme in contact with the nanoparticle, but not linked to the nanoparticle, and wherein the composition has an enhanced activity compared to a control psychrophilic enzyme.
A method of making an enzyme composition, the method comprising:
- contacting at least one nanoparticle wherein the nanoparticle comprises one or more of a cuprous oxide, a hydroxyapatite, magnesium chloride, manganese chloride, calcium chloride, zinc, magnesium, manganese, or a combination thereof and at least one psychrophilic enzyme, wherein the psychrophilic enzyme is in contact with the nanoparticle, but not linked to the nanoparticle, and wherein the composition has an enhanced activity compared to a control psychrophilic enzyme.
A method of treating a material, the method comprising:
- contacting the material with a composition, wherein the composition comprises:
- at least one nanoparticle, wherein the nanoparticle comprises one or more of a cuprous oxide, a hydroxyapatite, magnesium chloride, manganese chloride, calcium chloride, zinc, magnesium, manganese, or a combination thereof;
- and
- at least one psychrophilic enzyme in contact with the nanoparticle, but not linked to the nanoparticle, and wherein the composition has enhanced activity compared to a control psychrophilic enzyme.
