“…At the shallow site, transition to low pSRR (ca. 10 cmblf) correlated with the appearance of Desulfuromonas , a genus with cultured strains capable of reducing sulfate but also sulfur and iron (Greene, ; Pjevac et al, ). In sediments of the deep site that exhibited lowest pSRR (Fig.…”

Ferruginous (Fe-rich, SO -poor) conditions are generally restricted to freshwater sediments on Earth today, but were likely widespread during the Archean and Proterozoic Eons. Lake Towuti, Indonesia, is a large ferruginous lake that likely hosts geochemical processes analogous to those that operated in the ferruginous Archean ocean. The metabolic potential of microbial communities and related biogeochemical cycling under such conditions remain largely unknown. We combined geochemical measurements (pore water chemistry, sulfate reduction rates) with metagenomics to link metabolic potential with geochemical processes in the upper 50 cm of sediment. Microbial diversity and quantities of genes for dissimilatory sulfate reduction (dsrAB) and methanogenesis (mcrA) decrease with increasing depth, as do rates of potential sulfate reduction. The presence of taxa affiliated with known iron- and sulfate-reducers implies potential use of ferric iron and sulfate as electron acceptors. Pore-water concentrations of acetate imply active production through fermentation. Fermentation likely provides substrates for respiration with iron and sulfate as electron donors and for methanogens that were detected throughout the core. The presence of ANME-1 16S and mcrA genes suggests potential for anaerobic methane oxidation. Overall our data suggest that microbial community metabolism in anoxic ferruginous sediments support coupled Fe, S and C biogeochemical cycling.

“…A member of the Burkholderiaceae family, metallophilic gramnegative Cupriavidus metallidurans, has demonstrated to actively biomineralized particulate Au (Reith et al, 2009). Desulfuromonadaceae family contains members are capable of sulfur and Fe(III) reduction (Greene, 2014), and more recently Desulfuromonas soudanensis WTL was isolated using electrochemical enrichments from anoxic deep subsurface brine (Badalamenti et al, 2016) with 38 multiheme cytochromes. In this study, the relative predominance of Desulfuromonadaceae at lower and higher potentials indicates their ability to survive/grow in niches (Figure 3F).…”

“…2; Table S1). Members of the family Desulfuromonadaceae are anaerobic, but some of them are tolerant to molecular oxygen and found in various anoxic environments (Greene 2014). They play important roles in the biodegradation of organic compounds, including organic acids, aromatic and chlorinated compounds, and most members of Desulfuromonadaceae have a respiratory metabolism, while some are almost exclusively fermentative.…”

Investigating the microbial community structure and composition of toxic industrial wastes contaminated with nitrocellulose and various by-products is crucial for understanding the fate of these pollutants in the environment and for the development and application of effective bioremediation processes. In this study, we investigated the chemical properties and toxic potential of wastewater generated during nitrocellulose production. The analyzed wastewater from settling pond contained nitrocellulose powder particles as well as increased ammonium (570-760 mg/L), sulfate (1625-2045 mg/L) and sulfite (864-1014 mg/L) concentrations. The toxicity test results demonstrated that the wastewater samples present acute toxicity for Paramecium caudatum and Daphnia magna. Furthermore, bacterial community structure in the samples was characterized by pyrosequencing of 16S rRNA genes. Phylogenetic analysis of bacterial sequences indicated that Proteobacteria, Bacteroidetes and Firmicutes were the main phyla in the sample near inlet, whereas various phylotypes of the phyla Proteobacteria, Chlorobi, Bacteroidetes and Gemmatimonadetes dominated in the sample near outlet. Some bacterial members observed in the current work can be considered as agents capable of performing biodegradation of various hazardous contaminants, indicating that the described bacterial communities have a high potential for the development of effective bioremediation strategies.
