Study of microbial functional structure in Xiangjiang River sediment

Project description:Xiangjiang River (Hunan, China) has been contaminated with heavy metal for several decades by surrounding factories. However, little is known about the influence of a gradient of heavy metal contamination on the diversity, structure of microbial functional gene in sediment. To deeply understand the impact of heavy metal contamination on microbial community, a comprehensive functional gene array (GeoChip 5.0) has been used to study the functional genes structure, composition, diversity and metabolic potential of microbial community from three heavy metal polluted sites of Xiangjiang River.

Microbial community composition in sediments resists perturbation by nutrient enrichment

Project description:Functional redundancy in bacterial communities is expected to allow microbial assemblages to survive perturbation by allowing continuity in function despite compositional changes in communities. Recent evidence suggests, however, that microbial communities change both composition and function as a result of disturbance. We present evidence for a third response: resistance. We examined microbial community response to perturbation caused by nutrient enrichment in salt marsh sediments using deep pyrosequencing of 16S rRNA and functional gene microarrays targeting the nirS gene. Composition of the microbial community, as demonstrated by both genes, was unaffected by significant variations in external nutrient supply, despite demonstrable and diverse nutrient–induced changes in many aspects of marsh ecology. The lack of response to external forcing demonstrates a remarkable uncoupling between microbial composition and ecosystem-level biogeochemical processes and suggests that sediment microbial communities are able to resist some forms of perturbation.

Transcriptome-stable isotope probing provides targeted functional and taxonomic insights into hypoxic pollutant-degrading aquifer microbiota

Project description:We investigated a contaminant-degrading microbial community by sequencing total RNA (without rRNA depletion) from microcosms containing sediment from a hypoxic contaminated aquifer fed with isotopically labeled toluene.

A transcriptomics approach to compare transcriptomes of individual methylotrophs from Lake Washington sediment in artificial communities and in pure cultures.

Project description:We established simple synthetic microbial communities in a microcosm model system to determine the mechanisms that underlay cross-feeding in microbial methane-consuming communities. Co-occurring strains from Lake Washington sediment were used that are involved in methane consumption, a methanotroph and two non-methanotrophic methylotrophs.

Meta-omics analysis of microbially induced carbonate precipitation at a CO2 rich geyser in Utah

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)
