“…In addition, investigations of potential methane oxidation have been performed with tundra and permafrost soils comprising both in situ and in vitro approaches (Whalen and Reeburgh, 1990;Roslev and Iversen, 1999;Berestovskaya et al, 2001;Liebner and Wagner, 2007). Despite the variety of studies of methanotrophy and methanotrophic bacteria in cold environments, this study is, to our knowledge, the first to address methanotrophy in an arctic glacier forefield.…”

“…MOB found in Arctic soils have temperature growth patterns ranging from psychrotrophic to mesophilic; these MOB communities can, therefore, respond to large temperature changes [26,[31][32][33]. However, physiological and ecological temperature responses and how these affect community CH 4 oxidation rates are not well understood.…”

The Influence of Above-Ground Herbivory on the Response of Arctic Soil Methanotrophs to Increasing CH4 Concentrations and Temperatures

Rising temperatures in the Arctic affect soil microorganisms, herbivores, and peatland vegetation, thus directly and indirectly influencing microbial CH4 production. It is not currently known how methanotrophs in Arctic peat respond to combined changes in temperature, CH4 concentration, and vegetation. We studied methanotroph responses to temperature and CH4 concentration in peat exposed to herbivory and protected by exclosures. The methanotroph activity was assessed by CH4 oxidation rate measurements using peat soil microcosms and a pure culture of Methylobacter tundripaludum SV96, qPCR, and sequencing of pmoA transcripts. Elevated CH4 concentrations led to higher CH4 oxidation rates both in grazed and exclosed peat soils, but the strongest response was observed in grazed peat soils. Furthermore, the relative transcriptional activities of different methanotroph community members were affected by the CH4 concentrations. While transcriptional responses to low CH4 concentrations were more prevalent in grazed peat soils, responses to high CH4 concentrations were more prevalent in exclosed peat soils. We observed no significant methanotroph responses to increasing temperatures. We conclude that methanotroph communities in these peat soils respond to changes in the CH4 concentration depending on their previous exposure to grazing. This “conditioning” influences which strains will thrive and, therefore, determines the function of the methanotroph community.

“…Extreme acidophiles are found in all three domains of life (Aguilera et al, 2016;Dopson, 2016;Golyshina et al, 2016) although the most extreme are from the Archaea domain that can survive at negative pH values (Tyson et al, 2004). In addition, a large diversity of moderate acidophiles with growth ranges from pH 3 to 7.5, but with optima between pH 4 and 5 inhabit an array of environments including arctic tundra soils (Berestovskaya et al, 2002), Sphagnum peat bogs (Dedysh et al, 1998), and sulfidic deep sea sediments (Reysenbach et al, 2006). Characterized extreme acidophiles have growth temperatures ranging from approximately 4 • C to >80 • C. However, the most well-studied species-type strains have temperature optima ≥30 • C including the model species, Acidithiobacillus ferrooxidans (Zhang et al, 2018;Moya-Beltrán et al, 2021).…”

Eurypsychrophilic acidophiles: From (meta)genomes to low-temperature biotechnologies

et al. 2023

Low temperature and acidic environments encompass natural milieus such as acid rock drainage in Antarctica and anthropogenic sites including drained sulfidic sediments in Scandinavia. The microorganisms inhabiting these environments include polyextremophiles that are both extreme acidophiles (defined as having an optimum growth pH < 3), and eurypsychrophiles that grow at low temperatures down to approximately 4°C but have an optimum temperature for growth above 15°C. Eurypsychrophilic acidophiles have important roles in natural biogeochemical cycling on earth and potentially on other planetary bodies and moons along with biotechnological applications in, for instance, low-temperature metal dissolution from metal sulfides. Five low-temperature acidophiles are characterized, namely, Acidithiobacillus ferriphilus, Acidithiobacillus ferrivorans, Acidithiobacillus ferrooxidans, “Ferrovum myxofaciens,” and Alicyclobacillus disulfidooxidans, and their characteristics are reviewed. Our understanding of characterized and environmental eurypsychrophilic acidophiles has been accelerated by the application of “omics” techniques that have aided in revealing adaptations to low pH and temperature that can be synergistic, while other adaptations are potentially antagonistic. The lack of known acidophiles that exclusively grow below 15°C may be due to the antagonistic nature of adaptations in this polyextremophile. In conclusion, this review summarizes the knowledge of eurypsychrophilic acidophiles and places the information in evolutionary, environmental, biotechnological, and exobiology perspectives.
