Abstract
A bacterial culture which comprises a Campylobacter-like species is provided. The bacterial culture is capable of oxidizing a sulfide compound in a fluid such as, for example, a produced brine. Also provided is a process for substantially reducing sulfide content in a fluid wherein the process comprises contacting the fluid with a bacterial culture which comprises a Campylobacter-like species.
Claims14
A biologically pure bacterial culture capable of oxidizing a sulfide to elemental sulfur in a fluid wherein said bacterial culture is a Campylobacter species selected from the group consisting of Campbylobacter sp. CVO (NRRL B-21472), Campylobacter sp. FWKO B (NRRL B-21473), and combinations thereof and said fluid is selected from the group consisting of brines, oil, gas, and combinations thereof.
A biologically pure culture of strain Campylobacter sp. CVO (NRRL B-21472).
A biologically pure culture of strain Campylobacter sp. FWKO S (NRRL B-21473).
A biologically pure bacterial culture capable of reducing a nitrate and oxidizing a sulfide in a fluid wherein said bacterial culture is a Campylobacter species selected from the group consisting of Campbylobacter sp. CVO (NRRL B-21472), Campylobacter sp. FWKO B (NRRL B-21473), and combinations thereof and said fluid is selected from the group consisting of brines, oil, gas, and combinations thereof.
