sp. nov., a neutrophilic iron-oxidizing and -reducing bacterium isolated from iron-rich freshwater sediments No Access

Abstract

A neutrophilic iron-oxidizing and -reducing bacterium, strain MIZ03, was previously isolated from a wetland in Ibaraki, Japan. Here, we report the detailed characteristics of this strain. It was motile with a single polar flagellum, and Gram-stain-negative. It could grow not only chemolithoautotrophically but also chemoorganotrophically by aerobic respiration and fermentation. Major cellular fatty acids were C 7/C 6, and C. Phylogenetic analyses indicated that strain MIZ03 belonged to the genus . This strain was closely related to with 98.5 % of 16S rRNA gene sequence similarity. Based on its phenotypic and genomic based characteristics, we conclude that strain MIZ03 represents a new species in the genus . We propose the name sp. nov. to accommodate this strain. The type strain is MIZ03 (=JCM 34246=DSM 113266). We also propose the name sp. nov., of which the type strain is DCY110 (=KCTC 52288=JCM 31441), for the effectively, but not yet validly, published name ‘’.
