    摘要: A metal ion that inhibits enzyme deactivation is bonded to a carrier and inhibits enzyme deactivation when contacted with a substrate for the enzyme. A carrier-bound metal ion such as ions of iron is particularly suitable for inhibiting deactivation of glucose isomerase when isomerizing glucose to fructose. Glucose isomerase life is remarkably prolonged by contacting carrier-bound iron ions with a glucose substrate solution prior to isomerizing with glucose isomerase.

    摘要: An antifouling structure in contact with seawater or at least its surface layer is made up of a beryllium copper alloy having a beryllium content lying in the range of 0.2% by weight to 2.8% by weight. While this antifouling structure is immersed in seawater, a beryllium or copper oxide film is formed on the surface layer of the beryllium copper alloy mother material and beryllium or copper ions are liberated from the exposed surface layer of the beryllium copper alloy mother material into seawater. As years go by, the beryllium or copper oxide film peels away from the beryllium copper alloy mother material. Due to indeterminate repetition of such peeling, the liberation of beryllium or copper ions from the exposed surface layer of the beryllium copper alloy mother material into seawater is sustained.
