Nov.: Mn(II) Oxidizing Representatives Of A Globally Distributed Clade Of Alpha-Proteobacteria From The Order Rhizobiales 2009 226 Several closely related Mn(II)-oxidizing alpha-Proteobacteriawere isolated from very different marine environments: strainSI85-9A1 from the oxic/anoxic interface of a stratified Canadianfjord, strain HTCC 2156 from the surface waters off the Oregonco...
Carbon Quantity And Quality Drives Variation In Cave Microbial Communities And Regulates Mn(II) Oxidation 2017 392 Cave ecosystems are carbon limited and thus are particularly susceptible to anthropogenic pollution. Yet, how carbon quality and quantity that can modulate the pathways and amount of Mn cycling in caves remains largely unknown. To explore Mn cycling,...
Characterization Of Acid-Tolerant H2/CO2-Utilizing Methanogenic Enrichment Cultures From An Acidic Peat Bog In New York State 2014 416 Two methanogenic cultures were enriched from acidic peat soil using a growthmedium buffered to c. pH 5. One culture, 6A, was obtained from peat afterincubation with H2/CO2, whereas culture NTAwas derived from a 104 dilution ofuntreated peat into a m...

Dark Carbon Fixation In The Columbia River’s Estuarine Turbidity Maxima: Molecular Characterization Of Red-Type Cbbl Genes And Measurement Of DIC Uptake Ratesin Response To Added Electron Donors 2013 293 Dark CO2 fixation has been shown to rival the importance of oxygenic photosynthesis in the global carbon cycle, especially in stratified environments, such as salt wedge estuaries. We investigated this process in the Columbia River estuary using a va...
Genome of Methanoregula Boonei 6A8 Reveals Adaptations To Oligotrophic Peatland Environments 2015 542 Analysis of the genome sequence of Methanoregula boonei strain 6A8, an acidophilic methanogen isolated from an ombrotrophic (rain-fed) peat bog, has revealed unique features that likely allow it to survive in acidic, nutrient-poor conditions. First, ...
Increased Abundance Of Gallionella Spp., Leptothrix Spp. And Total Bacteria In Response To Enhanced Mn And Fe Concentrations In A Disturbed Southern Appalachian High Elevation Wetland 2012 407 The Sorrento wetland hosts several Fe- and Mn-rich seeps that are reported to have appeared after the area was disturbed by recent attempts at development. Culture-independent and culture-based analyses were utilized to characterize the microbial com...
Isolation Of A Novel Acidiphilic Methanogen From An Acidic Peat Bog 2006 505 Acidic peatlands are among the largest natural sources of atmospheric methane and harbour a large diversity of methanogenic Archaea1. Despite the ubiquity of methanogens in these peatlands,indigenous methanogens capable of growth at acidic pH values ...
Methanobacterium Paludis Sp. Nov. And A Novel Strain Of Methanobacterium Lacus Isolated From Northern Peatlands 2014 584 Two mesophilic, hydrogenotrophic methanogens, designated strains SWAN1T and AL-21, were isolated from two contrasting peatlands: a near circumneutral temperate minerotrophic fen in New York State, USA, and an acidic boreal poor fen site in Alaska, US...
Methanogenesis In Mclean Bog, An Acidic Peat Bog In Upstate New York: Stimulation By H2/CO2 In The Presence Of Rifampicin, Or By Low Concentrations Of Acetate 2004 238 Acidic peat bog soils produce CH4 and although molecular biological studies have demonstrated the presence of diverse methanogenic populations in them, few studies have sustained methanogenesis by adding the CH4 precursors H2/CO2 or acetate, and few ...
Methanolinea Mesophila Sp. Nov., A Hydrogenotrophic Methanogen Isolated From Rice Field Soil, And Proposal Of The Archaeal Family Methanoregulaceae Fam. Nov. Within The Order Methanomicrobiales 2012 356 A novel mesophilic, hydrogenotrophic methanogen, designated strain TNRT, was isolated from an anaerobic, propionate-degradation enrichment culture that was originally established from a ricefield soil sample from Taiwan. Cells were non-motile rods, 2...

Nov., An Acidiphilic Methanogen Isolated From An Acidic Peat Bog 2011 400 A novel acidiphilic, hydrogenotrophic methanogen, designated strain 6A8T, was isolated from anacidic (pH 4.0–4.5) and ombrotrophic (rain-fed) bog located near Ithaca, NY, USA. Cultures weredimorphic, containing thin rods (0.2–0.3 mm in diameter and 0...
Microbial Sequencing Analyses Suggest the Presence of a Fecal Veneer on Indoor Climbing Wall Holds 2014 625 Artifcial climbing walls represent a unique indoor environment in which humans interact closely with a variety of surface types.
