Abstract

A novel bacterium, designated HMF3850, was isolated from freshwater collected from the Gyeong-an wetland, Republic of Korea. Cells were Gram-stain-negative, aerobic, straight rods, non-motile, and oxidase- and catalase-positive. Growth was observed at pH 6.0–8.0 and at 10–30 °C on R2A agar. Comparative analysis of 16S rRNA gene sequences revealed that strain HMF3850 is a member of the genus , sharing highest sequence similarities with HMF2925 (96.7 % 16S rRNA gene sequence similarity), JBR12 (95.0 %), Gsoil 085 (94.9 %) and DSM 17448 (94.7 %). The major fatty acids were iso-C, summed feature 3 (C 7 and/or C 6) and C. The predominant respiratory quinone was MK-7. The major polar lipids were phosphatidylethanolamine, phosphatidylinositol, one unidentified aminophospholipid, two unidentified aminolipids and eight unidentified polar lipids. The DNA G+C content was 38.5 mol %. On the basis of the evidence presented in this study, strain HMF3850 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HMF3850 (=KCTC 42851=CECT 9087).
