In the microbial world the dissimilatory sulfate-reducing bacteria (SRB) are unique in that they have the ability to utilize inorganic sulfate as a terminal electron acceptor. This respiratory process, occurring under anaerobic conditions, is conducted by SRB for the purpose of generating high energy compounds for biosynthetic reactions involved in their growth and maintenance. Because relatively large amounts of sulfate are required for this mode of life, a serious consequence resulting from the growth of sulfate reducers is the dissemination of massive quantities of hydrogen sulfide in their immediate vicinity. Because of the deleterious consequences that can result from the growth of sulfate reducers, microbiologists have been studying the physiology, biochemistry, and ecology of these microorganisms to learn how to control them in nature. |
