Geomicrobiology of Ferromanganese Deposits in Caves of the upper Tennessee River Basin 2012 5110 Ferromanganese deposits in epigenic cave systems located within the Knox Dolomite bedrock formation of the upper Tennessee River Basin were analyzed to determine the role of microbes in the cycling of manganese and the transformation of cave mineralo...
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 313 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...
Mn(II)-oxidizing Bacteria are Abundant and Environmentally Relevant Members of Ferromanganese Deposits in Caves of the Upper Tennessee River Basin 2013 125 The upper Tennessee River Basin contains the highest density of our nation’s caves; yet, little is known regarding speleogenesis or Fe and Mn biomineralization in these predominantly epigenic systems. Mn:Fe ratios of Mn and Fe oxide-rich bio?lms, coa...
Mn(II)-oxidizing Bacteria are Abundant and Environmentally Relevant Members of Ferromanganese Deposits in Caves of the Upper Tennessee River Basin 2013 1725 The upper Tennessee River Basin contains the highest density of our nation's caves; yet, little is known regarding speleogenesis or Fe and Mn biomineralization in these predominantly epigenic systems. Mn:Fe ratios of Mn and Fe oxide-rich biofilms, co...
Sustained Anthropogenic Impact in Carter Saltpeter Cave, Carter County, Tennessee and the Potential Effects On Manganese Cycling 2013 871 Anthropogenic impact is a pervasive problem in heavily trafficked cave systems and fecal contamination is equally problematic in many cave and karst waters worldwide. Carter Saltpeter Cave in Carter County, Tennessee exhibits Mn(III/IV) oxide coating...
