title: Lysobacter daecheongensis sp. nov., isolated from sediment of stream near the Daechung dam in South Korea.
abstract: A Gram-negative, aerobic, rod shaped, non-spore-forming bacterial strain, designated Dae08(T), was isolated from sediment of the stream near Daechung dam in South Korea, and was characterized in order to determine its taxonomic position, using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain Dae08(T) belongs to the family Xanthomonadaceae of the Gammaproteobacteria, and is related to Lysobacter brunescens ATCC 29482(T) (97.3%). The phylogenetic distances from any other species with validly published names within the genus Lysobacter were greater than 3.7%. The G+C contents of the genomic DNA of strain Dae08(T) was 69.3 mol%. The detection of a quinone system with Q-8 as the predominant compound and a fatty acid profile with iso-C(15:0), iso-C(17:1), omega9c, iso-C(17:0), iso-C(16:0), and iso-C(11:0) 3-OH as the major acids supported the affiliation of strain Dae08(T) to the genus Lysobacter. DNA-DNA relatedness between strain Dae08(T) and its phylogenetically closest neighbour was 28%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Dae08(T) (= KCTC 12600(T)) should be classified in the genus Lysobacter as the novel species, for which the name Lysobacter daecheongensis sp. nov. is proposed.
