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 |
