About: A lithoautotrophic, Fe(II) oxidizing, nitrate-reducing bacterium, strain 2002 (ATCC BAA-1479; =DSM 18807), was isolated as part of a study on nitrate-dependent Fe(II) oxidation in freshwater lake sediments. Here we provide an in-depth phenotypic and phylogenetic description of the isolate. Strain 2002 is a gram-negative, non-spore forming, motile, rod-shaped bacterium which tested positive for oxidase, catalase, and urease. Analysis of the complete 16S rRNA gene sequence placed strain 2002 in a clade within the family Neisseriaceae in the order Nessieriales of the Betaproteobacteria 99.3% similar to Pseudogulbenkiania subflava. Similar to P. sublfava, predominant whole cell fatty acids were identified as 16:17c, 42.4%, and 16:0, 34.1%. Whole cell difference spectra of the Fe(II) reduced minus nitrate oxidized cyctochrome content revealed a possible role of c-type cytochromes in nitrate-dependent Fe(II) oxidation. Strain 2002 was unable to oxidize aqueous or solid-phase Mn(II) with nitrate as the electron acceptor. In addition to lithotrophic growth with Fe(II), strain 2002 could alternatively grow heterotrophically with long-chain fatty acids, simple organic acids, carbohydrates, yeast extract, or casamino acids. Nitrate, nitrite, nitrous oxide, and oxygen also served as terminal electron acceptors with acetate as the electron donor.
