Reduction Of Trace Elements To The Elemental Form By Microorganisms
US Patent:
4728427, Mar 1, 1988
Filed:
Apr 3, 1987
Appl. No.:
7/034329
Inventors:
Nathaniel W. Revis - Oak Ridge TN
Suzanne B. Benson - Kingston TN
Tanya R. Osborne - Oak Ridge TN
Charles T. Hadden - Oak Ridge TN
Suzanne B. Benson - Kingston TN

Charles T. Hadden - Oak Ridge TN
International Classification:
C02F 334
US Classification:
210611
Abstract:
A process for reducing the concentration of ionic species of heavy metals in an aqueous waste solution by conversion to a corresponding elemental metal comprises contacting the waste solution containing ionic species of one or more heavy metals with a culture of Pseudomonas maltophilia ATCC 53510 in the presence of an amount of nutrient medium sufficient to satisfy nutritional requirements of cells of the culture of Pseudomonas maltophilia ATCC 53510. When the ionic species is other than Hg. sup. + or Hg. sup. ++, other species of Pseudomonas can be used.
Reduction Of Trace Elements To The Elemental Form By Microorganisms
US Patent:
4826602, May 2, 1989
Filed:
Feb 29, 1988
Appl. No.:
7/162022
Inventors:
Nathaniel W. Revis - Oak Ridge TN
Suzanne B. Benson - Kingston TN
Tanya R. Osborne - Oak Ridge TN
Suzanne B. Benson - Kingston TN
Tanya R. Osborne - Oak Ridge TN
Assignee:
Oak Ridge Research Institute - Oak Ridge TN
International Classification:
C02F 334
US Classification:
210611
Abstract:
A process for reducing the concentration of ionic species of heavy metals in an aqueous waste solution by conversion to a corresponding elemental metal comprises contacting the waste solution containing ionic species of one or more heavy metals with a culture of Pseudomonas maltiphilia ATCC 53510 in the presence of an amount of nutrient medium sufficient to satisfy nutritional requirements of cells of the culture of Pseudomonas maltiphilia ATCC 53510. When the ionic species is other than Hg. sup. + or Hg. sup. ++, other species of Pseudomonas can be used.
Conversion Of Inorganic Ions To Metal Sulfides By Microorganisms
US Patent:
4789478, Dec 6, 1988
Filed:
Jun 17, 1987
Appl. No.:
7/063579
Inventors:
Nathaniel W. Revis - Oak Ridge TN
Tanya R. Osborne - Oak Ridge TN
Charles T. Hadden - Oak Ridge TN
Tanya R. Osborne - Oak Ridge TN
Charles T. Hadden - Oak Ridge TN
International Classification:
C02F 162
C02F 334
C02F 334
US Classification:
210611
Abstract:
This invention relates to a process for reducing the concentration of heavy metal ions in an aqueous waste solution, comprising the steps of: (a) contacting the aqueous waste solution with a mixed culture of Citrobacter freundii and a dissimulatory sulfate reducer, in the presence of nutrient sufficient to satisfy the nutritional requirements of the mixed culture, for a time sufficient to produce sulfide ions from a sulfide-ion precursor in the aqueous waste solution or nutrient and to precipitate the heavy metal ions in the form of corresponding sulfides and (b) removing the thus-precipitated sulfides from the waste solution.
