Method for decreasing the concentration of sulfate reducing bacteria in an aqueous system

1. A method of controlling the growth of a sulfate reducing bacteria in an aqueous system comprising

introducing Brassicibacter mesophilus to the aqueous system at suitable conditions allowing growth of said B. mesophilus in the system, wherein an increase in the growth of Brassicibacter mesophilus inhibits growth of sulfate reducing bacteria of the genus Desulfovibrio in the system.

2. The method of claim 1 wherein the sulfate reducing bacteria is Desulfovibrio vulgaris.

3. The method of claim 1 , which is a batch method, whereby the aqueous system is contacted once with the Brassicibacter mesophilus.

4. The method of claim 1 , which is a continuous method, whereby the Brassicibacter mesophilus is repeatedly introduced into the aqueous system.

5. The method of claim 1 , wherein the aqueous system is contaminated with said sulfate-reducing bacteria after introduction of Brassicibacter mesophilus and wherein the presence of B. mesophilus in the system inhibits the growth of said sulfate reducing bacteria.

6. The method of claim 1 , wherein the aqueous system is a potable aqueous system, wastewater or an industrial aqueous system.

7. A method of controlling the growth of a sulfate reducing bacteria in aqueous systems involved in oil and gas production and transportation comprising

introducing Brassicibacter mesophilus to the aqueous system at suitable conditions allowing growth of said B. mesophilus in the system, wherein an increase in the growth of Brassicibacter mesophilus inhibits growth of sulfate reducing bacteria of the genus Desulfovibrio in the system.

8. The method of claim 7 , wherein said aqueous system into which B. mesophilus is introduced and growing is water that is injected into a subterranean oil-bearing formation during oil recovery.
