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.

Project description:Analysis of microbial gene expression in response to physical and chemical gradients forming in the Columbia River, estuary, plume and coastal ocean was done in the context of the environmental data base. Gene expression was analyzed for 2,234 individual genes that were selected from fully sequenced genomes of 246 prokaryotic species (bacteria and archaea) as related to the nitrogen metabolism and carbon fixation. Seasonal molecular portraits of differential gene expression in prokaryotic communities during river-to-ocean transition were created using freshwater baseline samples (268, 270, 347, 002, 006, 207, 212). Total RNA was isolated from 64 filtered environmental water samples collected in the Columbia River coastal margin during 4 research cruises (14 from August, 2007; 17 from November, 2007; 18 from April, 2008; and 16 from June, 2008), and analyzed using microarray hybridization with the CombiMatrix 4X2K format. Microarray targets were prepared by reverse transcription of total RNA into fluorescently labeled cDNA. All samples were hybridized in duplicate, except samples 212 and 310 (hybridized in triplicate) and samples 336, 339, 50, 152, 157, and 199 (hybridized once). Sample location codes: number shows distance from the coast in km; CR, Columbia River transect in the plume and coastal ocean; NH, Newport Hydroline transect in the coastal ocean at Newport, Oregon; AST and HAM, Columbia River estuary locations near Astoria (river mile 7-9) and Hammond (river mile 5), respectively; TID, Columbia River estuary locations in the tidal basin (river mile 22-23); BA, river location at Beaver Army Dock (river mile 53) near Quincy, Oregon; UP, river location at mile 74.

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. Microbial community structure was determined using PhyoChio (G3) 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. Microbial community structure was determined using PhyoChio (G3)

Project description:Microbial diversity in Yellow River Estuary

Project description:This experiment aimed to understand stress responses of microbial communities differing in chronic exposure to the photosynthesis inhibitor diuron, combining untargeted metatranscriptomics (RNA-seq) and dose-response design. First, river microbial communities were incubated for 5-weeks in microcosms 1/ under constant exposure to 4µg/L of diuron (stressed community) or 2/ without contamination (non-stressed community). Then, both communities were exposed for 1 hour to a gradient of diuron concentrations to investigate differences in stress responses after chronic exposure. This experimental design enabled the determination of contig response trends as well as sensitivity thresholds.

Project description:<p>Background The gut microbiota plays a significant role in modulating the growth and function of host muscle, and microbiota transplantation experiments provide compelling evidence of its capacity to improve muscle quality. Feeding faba beans improves the muscle quality of Yellow River carp. However, the changes in gut microbiota, along with the specific microorganisms, metabolic pathways, and regulatory mechanisms linked to the enhancement of muscle quality following faba bean consumption remain to be elucidated.</p><p>Results After a 6-week feeding trial with faba beans, growth performance decreased, but muscle texture improved (P < 0.05). Gut microbiota structure also changed, with increased relative abundances of Aeromonas, ZOR0006, Cetobacterium, and Atopobium. Following 8 weeks of whole-intestinal microbiota transplantation (WIMT) from faba bean-fed donors to basal diet-fed recipients of Yellow River carp, growth performance remained unchanged (P > 0.05), while muscle texture improved (P < 0.05). This improvement was mainly due to increased small-diameter muscle fibers, higher collagen levels, and reduced muscle fat content (P < 0.05), which partially replicated the muscle texture of donor fish. Moreover, WIMT promotes intestinal structure and barrier integrity, with significant changes in gut microbiota structure and metabolic profile. WIMT improved the muscle quality of Yellow River carp by regulating mitochondrial autophagy and adipocytokine signaling pathways through the gut-muscle axis. Cetobacterium somerae (C. somerae) and its metabolites, such as acetic acid, played a crucial role in this process. Further feeding experiments demonstrated that C. somerae and acetic acid reduced the crude fat content of muscle while increasing the crude protein and collagen (P < 0.05). C. somerae also mitigated muscle protein degradation under inflammatory and enhanced collagen (P < 0.05), thereby improving muscle texture.</p><p>Conclusion This study establishes that gut microbiota enhance muscle quality in Yellow River carp through WIMT, identifies C. somerae and its metabolite acetic acid as key contributors. The findings provide novel evidence for fish gut-muscle axis research and offer new scientific basis for improving Yellow River carp muscle quality.</p>
