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 C_15 : 0 iso (40.6 %), C_17 : 0 iso 3-OH (22.4 %), summed feature 3 (C_16 : 1ω7c and/or C_16 : 1ω6c; 9.3 %) and C_15 : 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).
