Chryseolinea soli sp. nov., isolated from soil.

A yellow-colored bacterium with gliding motility, strain KIS68-18, was isolated from a soil sample at Bijin Island in Tongyeong city, Republic of Korea. The cells were strictly aerobic, Gram-staining-negative, non-spore-forming, and rod-shaped. The strain grew at the range of 10-35°C (optimum, 25-30°C), pH 5.5-8.0 (optimum, 6.0-7.5), and 0-0.5% (w/v) NaCl. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain KIS68-18 was closely related to Chryseolinea serpens DSM 24574 (98.9%) and had low sequence similarities (below 92.6%) with other members of the family 'Cytophagaceae' in the phylum Bacteroidetes. The major respiratory quinone system was MK-7 and the predominant cellular fatty acids were Cω5c (38.8%), iso-C (18.5%), and summed feature 3 (Cω7c and/or Cω6c, 10.6%). The polar lipids consisted of phosphatidylethanolamine, one unidentified phospholipid, three unidentified aminophospholipids, two unidentified aminolipids, and five unidentified lipids. The DNA G + C content was 50.9%. Based on the phylogenetic, physiological, and chemotaxonomic data, stain KIS68-18 represents a novel species of the genus Chryseolinea, for which the name Chryseolinea soli sp. nov. is proposed. The type strain of Chryseolinea soli is KIS68-18 (= KACC 17327 = NBRC 113100).
