“…Udaeobacter is an aerobic heterotroph with numerous amino acid and vitamin auxotrophies, which probably obtains nutrients from dead microbial biomass [ 46 ]. At the same time, this bacterium is capable to oxidize the atmospheric trace gas H 2 to generate energy [ 46 ]. It is possible that the hydrogen arriving with the released coal gases stimulates the growth of Ca.…”

Thermophilic Chloroflexi Dominate in the Microbial Community Associated with Coal-Fire Gas Vents in the Kuznetsk Coal Basin, Russia

Thermal ecosystems associated with areas of underground burning coal seams are rare and poorly understood in comparison with geothermal objects. We studied the microbial communities associated with gas vents from the coal-fire in the mining wastes in the Kemerovo region of the Russian Federation. The temperature of the ground heated by the hot coal gases and steam coming out to the surface was 58 °C. Analysis of the composition of microbial communities revealed the dominance of Ktedonobacteria (the phylum Chloroflexi), known to be capable of oxidizing hydrogen and carbon monoxide. Thermophilic hydrogenotrophic Firmicutes constituted a minor part of the community. Among the well-known thermophiles, members of the phyla Aquificae, Deinococcus-Thermus and Bacteroidetes were also found. In the upper ground layer, Acidobacteria, Verrucomicrobia, Actinobacteria, Planctomycetes, as well as Proteobacteria of the alpha and gamma classes, typical of soils, were detected; their relative abundancies decreased with depth. The phylum Verrucomicrobia was dominated by Candidatus Udaeobacter, aerobic heterotrophs capable of generating energy through the oxidation of hydrogen present in the atmosphere in trace amounts. Archaea made up a small part of the communities and were represented by thermophilic ammonium-oxidizers. Overall, the community was dominated by bacteria, whose cultivated relatives are able to obtain energy through the oxidation of the main components of coal gases, hydrogen and carbon monoxide, under aerobic conditions.

“…Candidatus Udaeobacter and uncultured lineage ADurb.Bin063-1 from phylum Verrucomicrobia were particularly active in meadows. Candidatus Udaeobacter potentially oxidizes trace gas H 2 to generate energy and benefits antibiotics release in soil (Willms et al ., 2020). These are poorly characterized bacteria, yet they were active and potentially have traits to survive in harsh, competitive conditions with the ability to scavenge atmospheric trace gases.…”

Global warming changes the activity of soil microbial communities in high latitudes, which might result in higher greenhouse gas emissions. However, these microbial processes involved in GHG production and consumption are not thoroughly understood. We analyzed 116 soil metatranscriptomes from 73 tundra sites and investigated how bacterial and archaeal communities and their functions vary horizontally (i.e. vegetation type) and vertically (i.e. topsoil organic and mineral layers) during the summer season, in soil types that differed in pH, moisture, soil organic matter (SOM), and carbon and nitrogen content. Active microbial communities were significantly different in the organic and mineral soil layers. Additionally, the communities differed significantly between the different vegetation types both in the organic and mineral layers. Various plant polymer degraders were particularly active in shrub-dominated ecosystems with high SOM and low pH, less known mixotrophic groups (such as Chloroflexi) were active lower SOM and higher pH. Additionally, we detected transcripts of alphaproteobacterial methanothrophs, which potentially moderate methane release from tundra soils in deeper soil layer. Our results provide new insights into the diversity and activity of microbial communities of high latitudes under climate change.

“…Two more agricultural indicator ASVs were classified as “ Ca . Udeobacter,” which carries multiple genes for antibiotic resistance (Willms et al., 2020) and may therefore be competitive in agricultural soils which are often subjected to high antibiotic loads (Pruden et al., 2012; Uyaguari‐Díaz et al., 2018).…”

Ditching Nutrients: Roadside Drainage Networks are Hotspots for Microbial Nitrogen Removal

2021

Human modifications to the landscape have altered hydrological processes (e.g., reduced infiltration and increased surface runoff due to impervious surfaces). Reducing the impact of these modifications on the hydrological cycle has in turn required the implementation of stormwater control systems such as constructed wetlands, retention ponds, and canals that may be hotspots for nutrient transformations (Gold et al., 2019;Palta et al., 2017). Roadside ditches are stormwater control systems that are subjected to periodic inundations. These inundation events deliver nutrients and promote redox conditions favorable for biogeochemical transformations such as nitrogen (N) removal (McPhillips et al., 2016). Unlike many stormwater
