Pseudomonas segetis sp. nov., isolated from soil

Abstract

A Gram-negative, aerobic bacterium, designated strain FR1439(T), was isolated from the soil of Dokdo in the Republic of Korea. The cells of strain FR1439(T) were catalase- and oxidase-positive, motile and rod-shaped. Phylogenetic analysis of the 16S rRNA gene sequence revealed that it represents a distinct line of descent within the genus Pseudomonas. The levels of DNA-DNA relatedness between strain FR1439(T) and type strains of phylogenetically related species, namely Pseudomonas flavescens, Pseudomonas mendocina, Pseudomonas pseudoalcaligenes and Pseudomonas straminea, ranged from 28 to 37%. Several phenotypic characteristics, together with the cellular fatty acid composition, can be used to differentiate strain FR1439(T) from related pseudomonads. On the basis of the polyphasic taxonomic evidence presented in this study, strain FR1439(T) represents a novel species, for which the name Pseudomonas segetis sp. nov. is proposed. The type strain is FR1439(T) (= IMSNU 14101(T) = CIP 108523(T) = KCTC 12331(T)).
