	abstract = {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 novel strains demonstrated their affiliation to the genus Geobacter. Strain G12(T) was most closely related to Geobacter pelophilus (94.7 \%) and Geobacter chapellei (94.1 \%). Strain G13(T) was most closely related to Geobacter grbiciae (95.3 \%) and Geobacter metallireducens (95.1 \%). Based on phylogenetic analyses and phenotypic differences between the novel isolates and other closely related species of the genus Geobacter, the isolates are proposed as representing two novel species, Geobacter argillaceus sp. nov. (type strain G12(T)=ATCC BAA-1139(T)=JCM 12999(T)) and Geobacter pickeringii sp. nov. (type strain G13(T)=ATCC BAA-1140(T)=DSM 17153(T)=JCM 13000(T)). Another isolate, strain R7(T), was derived from a primary kaolin deposit in Russia. The cells of strain R7(T) were motile, spore-forming, slightly curved rods, 0.6 x 2.0-6.0 microm in size and with up to six peritrichous flagella. Strain R7(T) was capable of reducing Fe(III) only in the presence of a fermentable substrate. 16S rRNA gene sequence analysis demonstrated that this isolate is unique, showing less than 92 \% similarity to bacteria of the Sporomusa-Pectinatus-Selenomomas phyletic group, including {\textquoteright}Anaerospora hongkongensis{\textquoteright} (90.2 \%), Acetonema longum (90.6 \%), Dendrosporobacter quercicolus (90.9 \%) and Anaerosinus glycerini (91.5 \%). On the basis of phylogenetic analysis and physiological tests, strain R7(T) is proposed to represent a novel genus and species, Pelosinus fermentans gen. nov., sp. nov. (type strain R7(T)=DSM 17108(T)=ATCC BAA-1133(T)), in the Sporomusa-Pectinatus-Selenomonas group.},

	abstract = {To further investigate the diversity of micro-organisms capable of conserving energy to support growth from dissimilatory Fe(III) reduction, Fe(III)-reducing micro-organisms were enriched and isolated from subsurface sediments collected in Oyster Bay, VA, USA. A novel isolate, designated T118(T), was recovered in a medium with lactate as the sole electron donor and Fe(III) as the sole electron acceptor. Cells of T1 18(T) were Gram-negative, motile, short rods with a single polar flagellum. Strain T1 18(T) grew between pH 6.7 and 7.1, with a temperature range of 4-30 degrees C. The optimal growth temperature was 25 degrees C. Electron donors utilized by strain T1 18(T) with Fe(III) as the sole electron acceptor included acetate, lactate, malate, propionate, pyruvate, succinate and benzoate. None of the compounds tested was fermented. Electron acceptors utilized with either acetate or lactate as the electron donor included Fe(III)-NTA (nitrilotriacetic acid), Mn(IV) oxide, nitrate, fumarate and oxygen. Phylogenetic analysis demonstrated that strain T1 18(T) is most closely related to the genus Rhodoferax. Unlike other species in this genus, strain T1 18(T) is not a phototroph and does not ferment fructose. However, phototrophic genes may be present but not expressed under the experimental conditions tested. No Rhodoferax species have been reported to grow via dissimilatory Fe(III) reduction. Based on these physiological and phylogenetic differences, strain T1 18(T) (=ATCC BAA-621(T) = DSM 15236(T)) is proposed as a novel species, Rhodoferax ferrireducens sp. nov.},
