Project description:The increased urban pressures are often associated with specialization of microbial communities. Microbial communities being a critical player in the geochemical processes, makes it important to identify key environmental parameters that influence the community structure and its function.In this proect we study the influence of land use type and environmental parameters on the structure and function of microbial communities. The present study was conducted in an urban catchment, where the metal and pollutants levels are under allowable limits. The overall goal of this study is to understand the role of engineered physicochemical environment on the structure and function of microbial communities in urban storm-water canals. Water and sediment samples were collected after a rain event from Sungei Ulu Pandan watershed of >25km2, which has two major land use types: Residential and industrial. Samples were analyzed for physicochemical variables and microbial community structure and composition. Functional gene abundance was determined using GeoChip.

Project description:Here we provide dataset from a proteomic experiment, using trypsin digestion, and reversed-phase chromatography (RPC) with tandem mass spectrometr (RPC-MS/MS), in order to relatively quantify the protein composition of skin mucus of Prussian carp Carassius gibelio. The main aim of the project is to identify the proteins specifically assotiated with fish inhabits euthophic shallow lakes lake Chany Lake (West Siberia).

Project description:Recent studies have unveiled the deep sea as a rich biosphere, populated by species descended from shallow-water ancestors post-mass extinctions. Research on genomic evolution and microbial symbiosis has shed light on how these species thrive in extreme deep-sea conditions. However, early adaptation stages, particularly the roles of conserved genes and symbiotic microbes, remain inadequately understood. This study examined transcriptomic and microbiome changes in shallow-water mussels Mytilus galloprovincialis exposed to deep-sea conditions at the Site-F cold seep in the South China Sea. Results reveal complex gene expression adjustments in stress response, immune defense, homeostasis, and energy metabolism pathways during adaptation. After 10 days of deep-sea exposure, shallow-water mussels and their microbial communities closely resembled those of native deep-sea mussels, demonstrating host and microbiome convergence in response to adaptive shifts. Notably, methanotrophic bacteria, key symbionts in native deep-sea mussels, emerged as a dominant group in the exposed mussels. Host genes involved in immune recognition and endocytosis correlated significantly with the abundance of these bacteria. Overall, our analyses provide insights into adaptive transcriptional regulation and microbiome dynamics of mussels in deep-sea environments, highlighting the roles of conserved genes and microbial community shifts in adapting to extreme environments.

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.

Project description:We developed a method that allows measuring the stable carbon isotope composition of individual species in microbial communities using metaproteomics. We call this methods “Direct Protein-SIF”. We validated and tested the method extensively using pure cultures (PXD006762) and mock communities (PXD006118, https://www.ebi.ac.uk/pride/archive/projects/PXD006118). As a case study we applied Direct Protein-SIF to the Olavius algarvensis symbiosis. Olavius algarvensis is a marine worm that lives in shallow-water sediments off the coast of Elba, Italy. The worm has no digestive and excretory system, instead it harbors five bacterial symbionts that fulfill its nutritional and waste recycling needs (http://www.pnas.org/content/109/19/E1173.short). For this project we generated metaproteomes of 14 O. algarvensis individuals. A total of 18 LC-MS/MS runs were generated. For Direct Protein-SIF the data from all runs was combined. In this submission we are including the Direct Protein-SIF specific isotope pattern file as well as the .mzML files and PSM file required as input for the Direct Protein-SIF software (Calis-p). In addition to the Olavius algarvensis samples a protein reference material (MKH files) was measured. The respective .raw files and isotopic pattern files are available through project PXD006762 (see publication for details on how the reference material is used to calibrate the method).
