| macroscopic streamer growths in acidic, metal-rich mine waters in north wales consist of novel and remarkably simple bacterial communities. | the microbial composition of acid streamers (macroscopic biofilms) in acidic, metal-rich waters in two locations (an abandoned copper mine and a chalybeate spa) in north wales was studied using cultivation-based and biomolecular techniques. known chemolithotrophic and heterotrophic acidophiles were readily isolated from disrupted streamers, but they accounted for only <1 to 7% of the total microorganisms present. fluorescent in situ hybridization (fish) revealed that 80 to 90% of the microbes in ... | 2006 | 16517651 |
| biodiversity and geochemistry of an extremely acidic, low-temperature subterranean environment sustained by chemolithotrophy. | the geochemical dynamics and composition of microbial communities within a low-temperature (ôê+8.5-¦c), long-abandoned (>ôçâ90 years) underground pyrite mine (cae coch, located in north wales) were investigated. surface water percolating through fractures in the residual pyrite ore body that forms the roof of the mine becomes extremely acidic and iron-enriched due to microbially accelerated oxidative dissolution of the sulfide mineral. water droplets on the mine roof were found to host a very li ... | 2011 | 21382147 |
