The acidification of water in mining areas is a global environmental issue primarily catalyzed by sulfur-oxidizing bacteria (SOB). Little known about microbial sulfur cycling circumneutral pH mine tailing impoundment waters. Here we investigate biological oxidation over four years tailings cap, integrating aqueous geochemistry, genome-resolved metagenomics and metatranscriptomics. community consistently dominated neutrophilic, chemolithoautotrophic SOB (relative abundances ~76% 2015, ~55%...
Abstract The aim of this study was to determine the influence leaf‐litter type ( i.e., European beech— Fagus sylvatica L. and ash— Fraxinus excelsior L.) mixture on partitioning C N between O horizon, topsoil, soil microbial biomass, CO 2 emission during decomposition. In a mature beech stand Hainich National Park, Thuringia, Germany, undisturbed cores (∅︁ 24 cm) were transferred plastic cylinders original leaf litter either replaced by 13 15 N‐labeled or ash litter, leaf‐litter‐mixture...
<title>Abstract</title> In mine wastewaters, three microbial sulfur oxidation pathways have the potential to cause different water quality outcomes that can differ from abiotic model sulfate and acidity predictions, currently used monitor risks. However, studies integrating microbiology geochemistry in active tailings impoundments, are very limited. Here, we developed a novel diagnostic approach detect microbially driven pathways. Within this 28-day study, eight, on-site, 500 L mesocosms...
Abstract Acidification of freshwater in mining impacted areas is a major global environmental problem catalyzed by sulfur-oxidizing bacteria (SOB). To date, little known about the active mine tailings impoundments and their niches. Here, biological sulfur oxidation was investigated over four years impoundment, integrating geochemistry, genome-resolved metagenomics metatranscriptomics. We demonstrated oxygen driven niche partitioning SOB metabolic pathways that explain acidity generation...
368 It is commonly observed that successful elite distance runners are smaller in body size than non-elite runners. From this one could speculate a mass (MB) represents determinant of running performance. To evaluate issue, the present study solicited local competitive to fill out questionnaire detailing either actual or predicted personal best times for flat races (1.61-42.18 km) within previous year. The analysis included data from 8 women (20±1.4 yrs age, 55±5.2 kg, 44±21 km·week−1...
