ABSTRACT
Designated strain K5T was isolated from soil on Jeju Island. The bacterium was aerobic, Gram-stain-negative, oxidase-positive, catalase-low activity, motile, short-rod shaped, opaque and formed white colonies that were circular, raised and had entire margins. Strain K5T was able to grow at 15-40 °C, pH 4-9 and at 0-2â% (w/v) NaCl concentration. Phylogenetic analysis based on its 16S rRNA gene sequences indicated that strain K5T is closely related to Ferrovibrio soli A15T (98.9â% sequence similarity), Ferrovibrio denitrificans Sp-1T (98.7â%) and Ferrovibrio xuzhouensis LM-6T (97.4â%). The sole respiratory quinone was determined to be ubiquinone-10. The dominant fatty acids of strain K5T were summed feature 8 (C18ââ1 ω7c / C18ââ1ω6c, 29.8â%), C19ââ0 cyclo ω8c (20.2â%) and C16ââ0 (24.4â%). DNA G+C content was 63.6â% and DNA-DNA relatedness between strain K5T and other three members of the genus Ferrovibrio ranged from 24 to 28â%. The major polar lipids were identified as phosphatidylglycerol, phosphatidylethanolamine and aminolipids. Moreover, polyphasic characterization revealed that strain K5T represents a novel species in the genus Ferrovibrio, for which the name Ferrovibrio terrae sp. nov. is proposed. The type strain is K5T (=KCCM 43295T=LMG 30611T).
