Project description:The thermophilic Aquificales inhabit and play important biogeochemical roles in the geothermal environments globally. Although intensive studies on physiology, microbial ecology, biochemistry, metagenomics and metatranscriptomics of the Aquificales¬ species and Aquificales-containing environmental samples have been conducted, comprehensive understandings about their ecophysiology, especially in the natural niches have been limited. In the present study, an integrated suite of metagenomic, metatranscriptomic and metaproteomic analyses, for the first time, were conducted on a filamentous microbial community from the Apron and Channel Facies (ACF) of CaCO3 (travertine) deposition at Narrow Gauge, Mammoth Hot Springs, Yellowstone National Park.

Project description:Microbially induced carbonate precipitation (MICP) refers to the biogeochemical process in which calcium carbonate is precipitated by altering the local geochemical environment (Mortensen et al. 2011). These alterations occur as a by-product of common microbial metabolic activities by increasing the local carbonate content as well as pH thereby saturating the solution in respect to carbonate. To better understand the microbial ecology of MICP on a community level in natural environments, we chose to evaluate microbial communities derived from travertine adjacent to Crystal Geyser (CG), Utah. CG is a cold-driven, CO2 rich geyser which is surrounded by colorful travertine that has been suggested to be generated through microbial processes. We used a cultivation-independent, multi-omics approach combined with geochemical measurements to investigate metabolic pathways and physiologies potentially involved in MICP at CG. We collected samples from the top 20 cm of travertine adjacent to Crystal Geyser, Utah in November 2019 and June 2021 (38.9384° N, 110.1354° W) wearing gloves at all times. We sampled 1 m away from the borehole (CG-1) and 10 m away from the borehole (CG-10). We preserved all collected samples in RNAlater-like solution (Menke et al., 2017, Front. Microbiol. 8) in a 1:10 sediment: RNAlater-like solution ratio as previously validated (Jensen et al. (2021, Micro. Spec. 2021, 9:2)

Project description:Understanding biological diversity and distribution patterns at multiple spatial scales is a central issue in ecology. Here, we investigated the biogeographical patterns of functional genes in soil microbes from 24 arctic heath sites using GeoChip-based metagenomics and principal coordinates of neighbour matrices (PCNM)-based analysis. Functional gene richness varied considerably among sites, while the proportions of each major functional gene category were evenly distributed. Functional gene composition varied significantly at most medium and broad spatial scales, and the PCNM analyses indicated that 14-20% of the variation in total and major functional gene categories could be attributed primarily to relatively broad-scale spatial effects that were consistent with broad-scale variation in soil pH and total nitrogen. The combination of variance partitioning and multi-scales analysis indicated that spatial distance effects contributed 12% to variation in functional gene composition，whereas environmental factors contributed only 3%. This relatively strong influence of spatial as compared to environmental variation in determining functional gene distributions contrasts sharply with typical microbial phylotype/species-based biogeographical patterns in the Arctic and elsewhere. Our results suggest that the distributions of soil functional genes cannot be predicted from phylogenetic distributions because spatial factors associated with historical contingencies are relatively important determinants of their biogeography.
