Microbial Functional Gene Diversity Predicts Groundwater Contamination and Ecosystem Functioning
Contamination from anthropogenic activities has significantly impacted Earth's biosphere. However, knowledge about how environmental contamination affects the biodiversity of groundwater microbiomes and ecosystem functioning remains very limited. Here, we used a comprehensive functional gene array to analyze groundwater microbiomes from 69 wells at the Oak Ridge Field Research Center (Oak Ridge...
متن کاملAdaptation to and biodegradation of xenobiotic compounds by microbial communities from a pristine aquifer.
The ability of subsurface microbial communities to adapt to the biodegradation of xenobiotic compounds was examined in aquifer solids samples from a pristine aquifer. An increase in the rates of mineralization of radiolabeled substrates with exposure was used as an indication of adaptation. For some compounds, such as chlorobenzene and 1,2,4-trichlorobenzene, slight mineralization was observed ...
متن کاملMicrobial Diversity: Genetic Diversity Vs Functional Diversity
Diversity is the main descriptor of community structure and is a determining factor in the dynamics and function of ecological communities [1]. However, the latter implicitly differs based on the different types of organisms and their relative abundance within the community which is considered to be significant [2]. Research in microbial ecology focuses on the study of microbial community dynam...

متن کاملMicrobial colonization of aquifer sediment exposed in a groundwater well in northern Germany.
Microbial growth within the water-saturated subsurface environment was investigated by exposing sandy sediments to groundwater for 12 weeks at a depth of 10 or 20 m in a stainless-steel groundwater well. Washing and heating the sediment to 600 degrees C (removal of organic carbon) prior to the exposure did not prevent the natural microbial community from colonizing the sterilized sediment sampl...
