gen. nov., sp. nov. isolated from an artificial wetland in Okcheon, Korea No Access

Abstract

Strain GY_H was isolated from an artificial wetland in Okcheon, Chungcheongbuk-do Province, Republic of Korea. Strain GY_H was closely related to CC-BB4 based on 16S rRNA gene sequences (94.7 % similarity) and clustered within the family . Cells of the isolate were Gram-stain-negative, catalase-negative and oxidase-positive, and colonies were white or pale transparent. A flagellum was observed, and the isolate could respire both aerobically and anaerobically. Growth of GY_ H was observed in the following conditions: 10–45 °C, pH 5–11 and 0–4 % NaCl. The optimal conditions for growth were 25 °C, pH 6.5–7.5 and 0.5–1.5 % NaCl. The major fatty acids were C cyclo 8 (35.8 %) and summed feature 8 (C 7/C 6; 27.4 %). The major quinone was found to be ubiquinone-10. Diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine were the major polar lipids. The G+C content of the genome of GY_H was 63.3 mol%. Based on its phylogenomic, physiological and biochemical attributes, strain GY_H represents a novel species of a novel genus of the family . We propose the name as gen. nov., sp. nov. The type strain is GY_H (=KCTC 62792=JCM 32856).
