Abstract
A method for recycling metals is provided by using extracellular proteins excreted by a specific thermophilic bacteria strain, Tepidimonas fonticaldi sp. nov., in which the extracellular proteins show excellent metal-ion binding ability, being useful in recycling rare earth metal ions and precious metal ions from geothermal fluids, boiler solutions, industrial wastewater or hard water.
Claims12
A method for recycling metals, comprising:
- providing a liquid containing metal ions;
- contacting the liquid with an extracellular protein(s) excreted by an isolated thermophilic bacteria strain to form a complex of the metal ion and the protein;
- and
- collecting the complex;
- wherein the isolated thermophilic bacteria strain is Tepidimonas fonticaldi sp. nov., internationally deposited in the Korean Collection of Type Culture (KCTC) with deposit number of KCTC 12528BP.
A method for recycling metals in the treatment of boiler equipment, water pipelines, geothermal wells, industrial wastewater or hard water, wherein the method comprises:
- providing a liquid containing metal ions;
- contacting the liquid with an extracellular protein(s) excreted by an isolated thermophilic bacteria strain to form a complex of the metal ion and the protein;
- and
- collecting the complex;
- and
- wherein the isolated thermophilic bacteria strain is Tepidimonas fonticaldi sp. nov., internationally deposited in the Korean Collection of Type Culture (KCTC) with deposit number of KCTC 12528BP.
