Chryseolinea flava sp. nov., a new species of Chryseolinea isolated from soil.

A pale yellow bacterial strain, designated SDU1-6T, was isolated from a soil sample collected in the Jinan campus of Shandong University, Shandong Province, PR China. The strain was aerobic, motile, Gram-stain-negative and rod-shaped. Cellular growth occurred at 13-37 °C, pH 5.0-10.0 and with 0-0.1 % (w/v) NaCl, and the optimal growth was at 25 °C and pH 7.5. SDU1-6T had the highest 16S rRNA gene similarity of 95.42 % with Chryseolinea serpens DSM 24574T. The genome was 6 542 746 bp in length with 43.5 mol% DNA G+C content. The major fatty acids of SDU1-6T were C16 : 1ω5 and iso-C15 : 0, the major menaquinone was menaquinone-7 (MK-7) and the major polar lipid was phosphatidylethanolamine. On the basis of the polyphasic evidence and the 16S rRNA gene sequence, SDU1-6T represents a novel species of the genus Chryseolinea, for which the name Chryseolineaflava sp. nov. is proposed. The type strain is SDU1-6T (=CGMCC 1.13492T=JCM 32520T).
