Abstract A Gram-negative, yellow-pigmented bacterial strain, designated IPC6T, was isolated from soil in an arid region of Goyang-si (Gyeonggi-do, South Korea). Cells were strictly aerobic, non-spore-forming, rod-shaped. The strain grew within a temperature range of 10–42°C (optimum, 30°C) and pH of 5.0–11.0 (optimum, pH 8.0) in the presence of 0–2% (w/v) NaCl. Phylogenetically, the novel strain was closely related to members of the Lysobacter genus based on 16S rRNA sequence similarity, and showed the highest sequence similarity to Lysobacter niastensis KACC 11588T (98.5%). The predominant fatty acids were iso-C15:0, iso-C16:0, and summed feature 9 (iso-C17:1 ω9c), with Q-8 identified as the major ubiquinone. The polar lipid content included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unknown aminophospholipid, and an unidentified phospholipid. DNA-DNA hybridization results indicated that the strain IPC6T was distinct from Lysobacter niastensis KACC 11588T (37.9 ± 0.14%), Lysobacter panacisoli KACC 17502T (56.4 ± 0.13%), Lysobacter soli KCTC 22011T (8.1 ± 0.04%), Lysobacter gummosus KCTC 12132T (9.6 ± 0.03%), and Lysobacter cavernae KCTC 42875T (37.5 ± 0.14%), respectively. The DNA G + C content of the novel strain was 71.1 mol%. Based on the collective phenotypic, genotypic and chemotaxonomic data, the IPC6T strain is considered to represent a novel species in the genus Lysobacter, for which the name Lysobacter pedocola sp. nov. (= KCTC 42811T = JCM 31020T) is proposed.
