Abstract
A novel Gram-negative, aerobic, motile, short rod-shaped bacterium, designated J64T, was isolated from black sand collected from Soesoggak, Jeju Island, Korea. Cells grew at 4-37 degrees C, at pH 5.5-10.0 and with 0-10 % NaCl. The strain was found to be oxidase- and catalase-positive. Phylogenetic analyses showed that strain J64T belongs to the genus Pseudomonas, forming a monophyletic group with Pseudomonas pachastrellae, Pseudomonas pertucinogena and 'Pseudomonas denitrificans'. The 16S rRNA gene sequence similarity between strain J64T and type strains of all Pseudomonas species with validly published names was below 96.6 %. Low levels of DNA-DNA relatedness were found with respect to type strains of P. pachastrellae and P. pertucinogena, supporting the classification of strain J64T within a novel species of the genus Pseudomonas. Strain J64T contained C(18 : 1)omega7c (37.2 %), C(16 : 0) (20.4 %), summed feature 3 (17.4 %; comprising iso-C(15 : 0) 2-OH and/or C(16 : 1)omega7c) and C(12 : 0) (7.6 %) as major cellular fatty acids. On the basis of the phenotypic and phylogenetic data, strain J64T represents a novel species of the genus Pseudomonas, for which the name Pseudomonas sabulinigri sp. nov. is proposed. The type strain is J64T (=KCTC 22137T =JCM 14963T).
