geobacter pickeringii sp. nov., geobacter argillaceus sp. nov. and pelosinus fermentans gen. nov., sp. nov., isolated from subsurface kaolin lenses. | the goal of this project was to isolate representative fe(iii)-reducing bacteria from kaolin clays that may influence iron mineralogy in kaolin. two novel dissimilatory fe(iii)-reducing bacteria, strains g12(t) and g13(t), were isolated from sedimentary kaolin strata in georgia (usa). cells of strains g12(t) and g13(t) were motile, non-spore-forming regular rods, 1-2 mum long and 0.6 mum in diameter. cells had one lateral flagellum. phylogenetic analyses using the 16s rrna gene sequence of the n ... | 2007 | 17220454 |
psychrosinus fermentans gen. nov., sp. nov., a lactate-fermenting bacterium from near-freezing oxycline waters of a meromictic antarctic lake. | a novel, obligately anaerobic, fermentative bacterium, strain fcf9, was isolated from a 9-m water sample from permanently ice-covered, meromictic lake fryxell, antarctica. a phylogenetic analysis based on 16s rrna gene sequence identity clustered the antarctic isolate within the sporomusa-pectinatus-selenomonas phyletic group, where it was most closely related to pelosinus fermentans (95.5% sequence identity). however, unlike species of pelosinus, strain fcf9 was psychrophilic, with growth occur ... | 2008 | 18673392 |
microbial community succession during lactate amendment and electron-acceptor limitation reveals a predominance of metal-reducing pelosinus spp. | determining the success of in-situ bioremediation strategies is complex. by using controlled laboratory conditions, the influence of individual variables such as u(vi), cr(vi) and electron donor and acceptors on community structure, dynamics, and the metal-reducing potential can be studied. triplicate anaerobic, continuous-flow reactors were inoculated with cr(vi) contaminated groundwater from the hanford, washington 100-h area, amended with lactate and incubated for 95 days to obtain stable, en ... | 2012 | 22267668 |
pelosinus defluvii sp. nov., isolated from chlorinated solvent contaminated groundwater, emended description of the genus pelosinus, and transfer of sporotalea propionica to pelosinus propionicus comb. nov. | two anaerobic bacterial strains isolated from chlorinated solvent contaminated groundwater were characterized using a polyphasic approach. the strains, designated as shi-1t and shi-2, were found to be identical in phenotypic properties and shared high pairwise similarity (98.5 to 99.8%) in 16s rrna gene sequences. multiple 16s rrna genes were found to be present in strains shi-1t and shi-2 as well as in the type strains of pelosinus fermentans and sporotalea propionica. isolates shi-1t and shi-2 ... | 2011 | 21828012 |
