The influence of human settlement on the distribution and diversity of iron-oxidizing bacteria belonging to the Gallionellaceae in tropical streams
Among the neutrophilic iron-oxidizing bacteria (FeOB), Gallionella is one of the most abundant genera in freshwater environments. By applying qPCR and DGGE based on 16S rRNA gene-directed primers targeting Gallionellaceae, we delineated the composition and abundance of the Gallionellaceae-related FeOB community in streams differentially affected by metal mining, and explored the relationships b...
متن کاملIncreased 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
The Sorrento wetland hosts several Feand 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 community at the main site of the Fe and Mn seep. Several bacteria capable of oxidizing Mn(II) were isolated, including members related to the genera Ba...
متن کاملThe Occurrence of Gallionella in Salt Water.
A Gallionella sp. is described that lives and freely multiplies in sea water. The habitat of the organism has been thoroughly investigated and the possibility of accidental occurrence has been eliminated. The appearance of the Gallionella sp. described is quite different from the similar iron bacteria occurring in fresh water.
متن کاملDistribution and diversity of Gallionella-like neutrophilic iron oxidizers in a tidal freshwater marsh.
Microbial iron oxidation is an integral part of the iron redox cycle in wetlands. Nonetheless, relatively little is known about the composition and ecology of iron-oxidizing communities in the soils and sediments of wetlands. In this study, sediment cores were collected across a freshwater tidal marsh in order to characterize the iron-oxidizing bacteria (FeOB) and to link their distributions to...
متن کاملSurprising abundance of Gallionella-related iron oxidizers in creek sediments at pH 4.4 or at high heavy metal concentrations
We identified and quantified abundant iron-oxidizing bacteria (FeOB) at three iron-rich, metal-contaminated creek sites with increasing sediment pH from extremely acidic (R1, pH 2.7), to moderately acidic (R2, pH 4.4), to slightly acidic (R3, pH 6.3) in a former uranium-mining district. The geochemical parameters showed little variations over the 1.5 year study period. The highest metal concent...
