Lacibacter daechungensis sp. nov., isolated from deep freshwater of a reservoir.

A Gram-stain-negative, aerobic, motile by gliding, non-spore-forming, rod-shaped, orange-pigmented bacterium, designated strain H32-4(T), was isolated from 32 m deep water of Daechung reservoir in Daejeon, Republic of Korea. Based on the nucleotide sequence of the 16S rRNA gene, the closest neighbouring type strain was Lacibacter cauensis NJ-8(T) with which strain H32-4(T) shared 98.9% sequence similarity. The most abundant fatty acids in whole cells of strain H32-4(T) were C15 : 0 iso (40.6 %), C17 : 0 iso 3-OH (22.4%), summed feature 3 (C16:1ω7c and/or C16:1ω6c; 9.3%) and C15:0 (6.6 %). The predominant menaquinone was MK-7. The G+C content of the genomic DNA of strain H32-4(T) was 45.7 mol%. Thus, these combined genotypic and phenotypic data supported the conclusion that strain H32-4(T) represents a novel species of the genus Lacibacter, for which the name Lacibacter daechungensis sp. nov. is proposed. The type strain is H32-4(T) ( = KCTC 32395(T) = JCM 19172(T)).
