A yellow-pigmented bacterial strain, designated RCML-52T, was isolated from an abandoned gold mine in the desert in Xinjiang, China. Strain RCML-52T was Gram-negative, aerobic and non-motile. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RCML-52T was affiliated with the genus Lysobacter. Strain RCML-52T exhibited <95.6 % 16S rRNA gene sequence similarity to the type strains of all species of the genus Lysobacter. The major fatty acids were iso-C16 : 0 (27.6 %), iso-C15 : 0 (19.1 %), iso-C17 : 1 ω9c (16.4 %), iso-C11 : 0 3-OH (6.5 %) and iso-C11 : 0 (5.3 %). The DNA G+C content was 69.7 mol%. The major isoprenoid quinone was Q-8. On the basis of phylogenetic, phenotypic and chemotaxonomic analysis, strain RCML-52T should be assigned to a novel species of the genus Lysobacter, for which the name Lysobacter xinjiangensis sp. nov. is proposed. The type strain is RCML-52T (=CCTCC AB 208194T =KCTC 22558T).

A Gram-negative, non-sporulating, non-flagellated rod, designated BR-9T, was isolated from soil collected on the Korean peninsula. Strain BR-9T grew optimally at pH 6.0–7.0, at 30 °C and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BR-9T belonged to the genus Pedobacter and clustered with Pedobacter insulae DS-139T and Pedobacter koreensis WPCB189T. Strain BR-9T exhibited 98.2 and 97.5 % 16S rRNA gene sequence similarity with P. insulae DS-139T and P. koreensis WPCB189T, respectively, and <96.7 % sequence similarity with the type strains of other species in the genus Pedobacter. Strain BR-9T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C content of strain BR-9T was 38.5 mol%. DNA–DNA relatedness between strain BR-9T and P. insulae DS-139T and P. koreensis KCTC 12536T was 3.4–4.2 %, which indicated that the isolate was genetically distinct from these type strains. Strain BR-9T was also distinguishable by differences in phenotypic properties. On the basis of the data presented, strain BR-9T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter boryungensis sp. nov. is proposed.
