“…Desulfobulbus species can ferment lactate and ethanol (plus carbon dioxide) to acetate and propionate in the absence of sulfate, and many Desulfovibrio and Desulfomicrobium species grow by fermenting pyruvate to form acetate, carbon dioxide, and hydrogen as products (51,54,55). In comparison, Desulforegula and Desulfatiferula were not detected in the inner layers, as the ability of these SRB to ferment organic matter is limited (49,57).…”

“…However, in this study, we also observed the proliferation of SRB, which normally use on large-molecule organic substrates rather than on hydrogen, acetate, and propionate for growth. Desulforegula and Desulfatiferula are known to use long-chain fatty acids and long-chain alkenes to reduce sulfate (49,57). Also, some Desulfovibrio spp.…”

“…Also, Desulfobulbus and Desulfovibrio are reported to be numerically important in anaerobic methanogenic-sulfidogenic aggregates (40). Desulfatiferula is a genus that was newly defined by Cravo-Laureau et al (49), and members are mesophilic, Gram-negative sulfate-reducing bacteria.…”

bSimultaneous production of sulfide and methane by anaerobic sewer biofilms has recently been observed, suggesting that sulfate-reducing bacteria (SRB) and methanogenic archaea (MA), microorganisms known to compete for the same substrates, can coexist in this environment. This study investigated the community structures and activities of SRB and MA in anaerobic sewer biofilms (average thickness of 800 m) using a combination of microelectrode measurements, molecular techniques, and mathematical modeling. It was seen that sulfide was mainly produced in the outer layer of the biofilm, between the depths of 0 and 300 m, which is in good agreement with the distribution of SRB population as revealed by cryosection-fluorescence in situ hybridization (FISH). SRB had a higher relative abundance of 20% on the surface layer, which decreased gradually to below 3% at a depth of 400 m. In contrast, MA mainly inhabited the inner layer of the biofilm. Their relative abundances increased from 10% to 75% at depths of 200 m and 700 m, respectively, from the biofilm surface layer. High-throughput pyrosequencing of 16S rRNA amplicons showed that SRB in the biofilm were mainly affiliated with five genera, Desulfobulbus, Desulfomicrobium, Desulfovibrio, Desulfatiferula, and Desulforegula, while about 90% of the MA population belonged to the genus Methanosaeta. The spatial organizations of SRB and MA revealed by pyrosequencing were consistent with the FISH results. A biofilm model was constructed to simulate the SRB and MA distributions in the anaerobic sewer biofilm. The good fit between model predictions and the experimental data indicate that the coexistence and spatial structure of SRB and MA in the biofilm resulted from the microbial types and their metabolic transformations and interactions with substrates. Sewer biofilms comprise complex multispecies microflora with a typical thickness of only about 1 mm (1). Depending on the electron donors and electron acceptors present in the wastewater, different carbon transformation processes can occur in close proximity in the sewer biofilms. Domestic wastewater normally contains a significant concentration (ca. 100 to 1,000 M) of sulfate but negligible nitrite and nitrate concentrations (2, 3). Therefore, under anaerobic conditions (which normally occur in pressure sewers fully filled with wastewater), sulfate reduction carried out by sulfate-reducing bacteria (SRB) could be an important terminal electron-accepting process in the sewer biofilms. The sulfate reduction activity in anaerobic sewers is important, as the production of sulfide can be transferred to the gas phase of partially filled gravity sewers and cause extensive corrosion of concrete sewer pipes (4, 5). Also, the emission of sulfide from sewers can cause odor problems for the surrounding area and pose health risks to sewer workers (6, 7). Apart from sulfate reduction, methanogenesis caused by the respiration of methanogenic archaea (MA) could also be a key terminal process in anaerobic sewer biofilms (8, 9). Guisasola and ...

Microbial transformation of hydrocarbons to methane is an environmentally relevant process taking place in a wide variety of electron acceptor-depleted habitats, from oil reservoirs and coal deposits to contaminated groundwater and deep sediments. Methanogenic hydrocarbon degradation is considered to be a major process in reservoir degradation and one of the main processes responsible for the formation of heavy oil deposits and oil sands. In the absence of external electron acceptors such as oxygen, nitrate, sulfate or Fe(III), fermentation and methanogenesis become the dominant microbial metabolisms. The major end product under these conditions is methane, and the only electron acceptor necessary to sustain the intermediate steps in this process is CO₂, which is itself a net product of the overall reaction. We are summarizing the state of the art and recent advances in methanogenic hydrocarbon degradation research. Both the key microbial groups involved as well as metabolic pathways are described, and we discuss the novel insights into methanogenic hydrocarbon-degrading populations studied in laboratory as well as environmental systems enabled by novel cultivation-based and molecular approaches. Their possible implications on energy resources, bioremediation of contaminated sites, deep-biosphere research, and consequences for atmospheric composition and ultimately climate change are also addressed.

“…Previous studies have reported the biodegradation of n-alkenes by mesophilic sulfate-reducing bacteria (namely, strains Hxd3 [1], Pnd3 [2], AK-01 [25], Desulfatibacillum aliphaticivorans strain CV2803 [11], Desulfatibacillum alkenivorans strain PF2803 [12], and Desulfatiferula olefinivorans strain LM2801 [10]). To our knowledge, this is the first report of the anaerobic oxidation of hydrocarbons, specifically n-alkenes, by a member of the domain Archaea and at a temperature as high as 70°C.…”
