Embodiment 1

[0048] Inhibition of Sulfide Production by Desulfovibrio Desulfovibrio G100A in Response to Anthracene Diol

[0049] Thaw 1 mL of the frozen culture of Desulfovibrio desulfuricans G100A (Desulfovibrio desulfuricans G100A), inject it into a test tube containing 10 mL of reducing-modified BTZ-3 medium covered by the septum, and incubate at 30 °C for 3 days (all during the experiment The transfer process, substance addition and sampling were performed in an anaerobic chamber at room temperature. The cultivation was performed outside this chamber.). 5 mL of this culture was transferred to a 60-mL septum-covered serum bottle containing 50 ml of reduced BTZ-3 medium and incubated overnight at 30°C. 3 ml of this culture was transferred to 50 ml of modified Postgate's B medium in a 60-mL serum bottle covered with a septum seal. A total of 6 cultures were thus prepared. The above four samples were then treated with two concentrations (100 ppm and 500 ppm) of the anthracene diol sal...

Embodiment 2

[0065] Anthracene diol inhibits sulfide production by Desulfovibrio desulfovibrio G100A

[0066] Thaw 1 mL of the frozen Desulfovibrio desulfovibrio G100A culture, inject it into a septum-covered test tube containing 10 mL of reduced-modified BTZ-3 medium, and incubate at 30°C for 3 days (all transfer procedures, material Addition and sampling were performed in an anaerobic chamber at room temperature. Incubation was performed outside the chamber.). 5 mL of this culture was transferred to a 60-mL septum-covered serum bottle containing 50 ml of reduced BTZ-3 medium and incubated overnight at 30°C. 3 ml of this culture was transferred to 50 ml of modified Postgate's B medium in a 60-mL serum bottle covered with a septum seal. A total of 6 cultures were thus prepared. The above four samples were then treated with two concentrations (140 ppm and 700 ppm) of the anthracene diol salt solution in duplicate by injecting the material into a septum vial with a microliter syringe and...

Embodiment 3

[0082] Two different anthracene diol salt solutions in inhibiting the sulfidation produced by Desulfovibrio desulfovibrio G100A comparison of things

[0083] Thaw 1 mL of the frozen Desulfovibrio desulfovibrio G100A culture, inject it into a septum-covered test tube containing 10 mL of reduced-modified BTZ-3 medium, and incubate at 30°C for 3 days (all transfer procedures, material Addition and sampling were performed in an anaerobic chamber at room temperature. Incubation was performed outside the chamber.). 5 mL of this culture was transferred to a 60-mL septum-covered serum bottle containing 50 ml of reduced BTZ-3 medium and incubated overnight at 30°C. 3 ml of this culture was transferred to 50 ml of modified Postgate's B medium in a 60-mL serum bottle covered with a septum seal. A total of 14 cultures were thus prepared. The substance was then injected into the analyte by using a microliter syringe with the following three concentrations (5, 10 and 50 mg / l equivalen...

Abstract

A non-biocidal method for inhibiting biogenic sulfide generation in a system having an anaerobic biofilm containing active sulfate-reducing bacteria comprising contacting the biofilm with an aqueous solution of anthrahydroquinone compound.

Description

[0001] related application [0002] This application is a continuation-in-part of co-pending US Patent Application Serial No. 08 / 719,120, filed September 24,1996. field of invention [0003] The present invention relates to methods for inhibiting biosulfide production. In particular, the present invention relates to methods for inhibiting sulfide production by sulfate reducing bacteria in aqueous liquid systems and fuel tanks. Background of the invention [0004] In the petroleum industry, uncontrolled microbial growth and activity can create serious operational, environmental, and human safety problems. Problems caused or exacerbated by microbial growth and activity include corrosion, solids formation, and sulfidation Hydrogen (H 2 S) Generation. [0005] The anaerobic environment in the petroleum industry mainly leads to H 2 S producing microorganisms are sulfate reducing bacteria. These microorganisms are ubiquitous and can grow in almost any environment. They are ...
