Abstract

A bacterial strain, designated IMCC1731, was isolated from an eutrophic freshwater pond and characterized using a polyphasic taxonomic approach. Cellular growth occurred at pH 6–9 (optimum, pH 8.0), at 10–30 °C (optimum, 25 °C) and with 0–1 % (w/v) NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain IMCC1731 belonged to the genus in the family and was most closely related to Gsoil 085 (98.1 %) followed by HMF3850 (95.0 %), DSM 17448 (94.7 %), HMF2925 (94.4 %) and JBR12 (94.0 %). The DNA–DNA relatedness between strain IMCC1731 and Gsoil 085 was 47±4 %. The DNA G+C content of strain IMCC1731 was 37.7 mol%. The predominant cellular fatty acids were summed feature 3 (C 6 and/or C 7) and iso-C Based on the physiological and chemotaxonomic characteristics, DNA–DNA relatedness and 16S rRNA gene phylogeny, stain IMCC1731 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is IMCC1731 (=KCTC 52248=JCM 31373).
