Abstract
A bacterial strain, GA2-M3T, isolated from a sea-sand sample in Korea, was subjected to polyphasic taxonomic characterization. Cells of strain GA2-M3T were Gram-negative, non-motile, non-spore-forming and short rod- to ovoid-shaped. Comparative 16S rRNA gene sequencing studies confirmed that the bacterium fell within the radiation of the genus Loktanella. Similarity levels between the 16S rRNA gene sequence of strain GA2-M3T and those of type strains of Loktanella species with validly published names were 93.5–96.1 %; highest sequence similarity was with Loktanella rosea. The G+C content of the genomic DNA of strain GA2-M3T was 60.0 mol% and the predominant ubiquinone was Q-10. Major fatty acids were 18 : 1ω7c, 18 : 0 and 18 : 1ω7c 11-methyl. On the basis of the evidence presented, it is proposed that strain GA2-M3T represents a novel species, for which the name Loktanella koreensis sp. nov. is proposed. The type strain is GA2-M3T (=KACC 11519T=DSM 17925T).
