TL;DRAbstract
Sulfate-reducing bacteria (SRB) and archaea are widespread in nature and have been found in virtually every anaerobic environment that has been investigated. They play an important role in the global sulfur cycle, and in marine sediments they can account for up to 50% of the total carbon mineralization process. The cellular morphology of SRB is highly diverse, and it is still used as an important taxonomic feature. Genus Thermodesulfobacterium is one of the deepest-branching bacterial phyla and encompasses only SRB. In the process of anaerobic respiration, SRB reduce sulfate to sulfide in a complicated reaction involving the transfer of eight electrons. A wide range of organic acids (e.g., acetate, propionate, butyrate, pentanoate, and hexanoate) at concentrations up to 20mM have been found in oil reservoirs. Results from cultivation-dependent experiments for estimation of the total number of SRB in produced water show a considerable variation. The use of highly specific fluorescent an
