  • Microbial control of hydrogen sulfide production by sulfate reducing bacteria
    Patent number: 4879240
    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.
