“…Species of the family Shewanellaceae, which are widely distributed in marine habitats ( Dikow, 2011 ), are facultative anaerobes, which under oxygen-depletion use, for example, thiosulfate, sulfite, or sulfur as an electron acceptor ( Burns and DiChristina, 2009 ). Moreover, Shewanella species are well-known as efficient players in the effective removal of various complex organic and inorganic pollutants (bioremediation) ( Zou et al, 2019 ).…”

The analysis of benthic bacterial community structure has emerged as a powerful alternative to traditional microscopy-based taxonomic approaches to monitor aquaculture disturbance in coastal environments. However, local bacterial diversity and community composition vary with season, biogeographic region, hydrology, sediment texture, and aquafarm-specific parameters. Therefore, without an understanding of the inherent variation contained within community complexes, bacterial diversity surveys conducted at individual farms, countries, or specific seasons may not be able to infer global universal pictures of bacterial community diversity and composition at different degrees of aquaculture disturbance. We have analyzed environmental DNA (eDNA) metabarcodes (V3–V4 region of the hypervariable SSU rRNA gene) of 138 samples of different farms located in different major salmon-producing countries. For these samples, we identified universal bacterial core taxa that indicate high, moderate, and low aquaculture impact, regardless of sampling season, sampled country, seafloor substrate type, or local farming and environmental conditions. We also discuss bacterial taxon groups that are specific for individual local conditions. We then link the metabolic properties of the identified bacterial taxon groups to benthic processes, which provides a better understanding of universal benthic ecosystem function(ing) of coastal aquaculture sites. Our results may further guide the continuing development of a practical and generic bacterial eDNA-based environmental monitoring approach.

Biogenic methane in shallow shale reservoirs has been proven to contribute to economic recovery of unconventional natural gas. However, whether the microbes inhabiting the deeper shale reservoirs at an average depth of 4.1 km and even co-occurring with sulfate-reducing prokaryote (SRP) have the potential to produce biomethane is still unclear. Stable isotopic technique with culture-dependent and independent approaches were employed to investigate the microbial and functional diversity related to methanogenic pathways and explore the relationship between SRP and methanogens in the shales in the Sichuan Basin, China. Although stable isotopic ratios of the gas implied a thermogenic origin for methane, the decreased trend of stable carbon and hydrogen isotope value provided clues for increasing microbial activities along with sustained gas production in these wells. These deep shale-gas wells harbored high abundance of methanogens (17.2%) with ability of utilizing various substrates for methanogenesis, which co-existed with SRP (6.7%). All genes required for performing methylotrophic, hydrogenotrophic and acetoclastic methanogenesis were present. Methane production experiments of produced water, with and without additional available substrates for methanogens, further confirmed biomethane production via all three methanogenic pathways. Statistical analysis and incubation tests revealed the partnership between SRP and methanogens under in situ sulfate concentration (~ 9 mg/L). These results suggest that biomethane could be produced with more flexible stimulation strategies for unconventional natural gas recovery even at the higher depths and at the presence of SRP.

“…Kimber et al demonstrated the bioreduction of Cu(II) to Cu(0); the resulted nanoparticles were well dispersed in the bodies of the S. oneidensis MR‐1 cells. The bioreduction mechanism was illustrated in detail as follows . As is well known, the cellular respiration of bacterium can adsorb and consume both organic and inorganic substances, including the oxygen, nitrite, thiosulfate, trimethylamine N ‐oxide (TMAO), and soluble metal composites as well as the metals including iron, manganese, chromium, and cobalt.…”

“…This biological technique for synthesizing metal nanoparticles had several advantages, including low cost, large‐scale production, nontoxicity, and controllability. Moreover, taking silver nanoparticles as an example, it is even possible to control the size and distribution of biogenic nanoparticles via controlling the expression of the genes encoding surface proteins . Based on the superior ability to produce metal nanoparticles, this system was proposed and verified to be effectively multifunctional while utilized in electrochemical fields.…”

Since rapidly increasing energy demands have aroused tremendous research activities on energy storage and conversion, microorganisms (e.g., bacteria, fungi, and viruses) have played significant roles in developing high‐performance electrodes due to their strong abilities of fast reproduction, biomineralization, gene modification, and self‐assembly. Recently, a large quantity of bacteria and fungi has been utilized as the precursors to produce heteroatom–doped carbons or as the biofactories and templates to biomineralize the metal ions to form carbon‐based composites. In addition, in virtue of easy genetic modification, nanoscale viruses with functional groups are directly used as biotemplates for the self‐assembly of the active materials. In this review, a detailed introduction on the microorganisms and their unique abilities as well as the mechanisms behind their operations are discussed. Moreover, recent progress on bacteria‐ and fungi‐derived carbon materials and their composites, as well as the virus‐templated bio‐materials as the electrodes in electrochemical fields, including batteries and electrocatalysts, are further summarized. Finally, challenges and perspectives on the development of the microorganism derivations in electrochemical fields are also provided. This review offers guidance for the rational design of advanced electrode materials from microorganisms and extend the energy systems from the man‐made to biofabrication.
