Groundwater metabolome responds to recharge in fractured sedimentary strata

Project description:<p>Understanding biogeochemical conversions of dissolved organic matter (DOM) in aquifers is paramount for the effective management of groundwater supplies. On its passage through the critical zone, DOM is subject to biogeochemical conversions and therefore carries cross-habitat information useful for monitoring and predicting the stability of groundwater ecosystem services. Groundwater metabolomics assesses this information. However, challenges arise from insufficient knowledge on groundwater metabolite composition and dynamics, and the necessity to maintain analytical conditions for long-term monitoring. We explored fractured sedimentary bedrock by 5-year untargeted metabolomics monitoring for oxic perched and anoxic phreatic sites along a hillslope recharge area, to evaluate DOM as groundwater tracer. Dimension reduction by principal component analysis revealed that metabolome dissimilarities between distant wells coincide with transient cross-stratal flow indicated by groundwater levels and environmental tracers. The metabolome was highly variable lacking seasonal patterns, and did not segregate by geographic location of sampling wells thus ruling out surface vegetation or (agricultura) land use as driving factor. The metabolome time series provide detailed insights into subsurface responses to recharge dynamics. Metabolomics monitoring provides information on groundwater flows, and allows concluding about below ground ecology and water quality evolution, required to understand the impact of interannual wet-dry cycles.</p>

Metaprotemic analysis of groundwaters from a coal tar-contaminated aquifer in South Glens Falls, NY: MW37, Shotgun 1

Project description:Deciphering the in situ activities of microorganisms is essential for understanding the biogeochemical processes occurring in complex environments. Here we used environmental metaproteomics to obtain information about the identity and activity of subsurface microbial populations in coal-tar-contaminated groundwater. The present study reports metaproteomic data showing high representation of Candidatus Methylomirabilis oxyfera in our study site’s subsurface microbial community. In addition, eight of the nine proteins of the n-damo pathway were identified—indicating that n-damo is an active process occurring in situ in this habitat.

Fermentative Spirochaetes drive nutrient cycling by a subsurface microbial loop in hydrocarbon-contaminated habitats

Project description:Members of the bacterial phylum Spirochaetes are primarily studied for their commensal and pathogenic roles in animal hosts. However, Spirochaetes are also frequently detected in anoxic hydrocarbon-contaminated environments but their ecological role in such ecosystems has so far remained unclear. Here we provide a functional trait to these frequently detected organisms with an example of a sulfate-reducing, naphthalene-degrading enrichment culture consisting of a sulfate-reducing deltaproteobacterium Desulfobacterium naphthalenivorans and a novel spirochete Rectinema cohabitans. Using a combination of genomic, proteomic, and physiological studies we show that R. cohabitans grows by fermentation of organic compounds derived from biomass from dead cells (necromass). It recycles the derived electrons in the form of H2 to the sulfate-reducing D. naphthalenivorans, thereby supporting naphthalene degradation and forming a simple microbial loop. We provide metagenomic evidence that equivalent associations between Spirochaetes and hydrocarbon-degrading microorganisms are of general importance in hydrocarbon- and organohalide-contaminated ecosystems. We propose that environmental Spirochaetes form a critical component of a microbial loop central to nutrient cycling in subsurface environments. This emphasizes the importance of necromass and H2-cycling in highly toxic contaminated subsurface habitats such as hydrocarbon-polluted aquifers.

Comparative transcriptional analysis of Desulfovibrio alaskensis G20, a choline utilization regulator and LysX

Project description:Expression data for Desulfovibrio alaskensis strain G20 and mutants in regulator proteins grown on lactate sulfate media and then pelleted and transferred to another media when they reached stationary phase. The Choline mutant was transferred to lacte/sulfate minimal media and choline/sulfate minimal media. The LysX mutant was transferred to minimal media with lysine and rich media. G20 was transferred to minimal media, choline/sulfate minimal media, lactate/choline/sulfate minimal media, minimal media with lysine, and rich media. We aimed to confirm or expand the regulons of each of the transposon interupted regulator mutants and compare gene expression responses of the regulators in different growth conditions. 10 samples were collected: 2 regulator mutants (2 conditions each), Desulfovibrio alaskensis G20 (5 conditions), 2 replicates for G20 minimal media condition. Control sample -G20 rich media.
