Microbial Control Of Hydrogen Sulfide Production By Sulfate Reducing Bacteria

US Patent:
4879240, Nov 7, 1989
Filed:
Jul 19, 1988
Appl. No.:
7/221152
Inventors:
Kerry L. Sublette - Tulsa OK
Maron E. Woolsey - Tulsa OK
Francis S. Manning - Tulsa OK
Anne D. Montgomery - San Antonio TX
Michael J. McInerney - Norman OK
Assignee:
Combustion Engineering, Inc. - Windsor CT
International Classification:
C12N 120
US Classification:
4352521
Abstract:
Mutant strains of Thiobacillus denitrificans are used to inoculate an environment containing sulfate and sulfate-reducing bacteria to control the net formation of sulfide. The mutant strains are tolerant of significant concentrations of soluble sulfides and may also be tolerant of glutaraldehyde which is a biocide effective against sulfate-reducing bacteria and which may also be added to the environment. One environment for use of the invention is in a water injection well for the secondary production of petroleum and another is the control of sulfide production in the treatment of waste materials.
