Abstract

A Gram-staining-negative bacterium, designated strain BLN2, was isolated from within the roots of reeds () in Beijing Cuihu Wetland (China) and characterized using a polyphasic taxonomic approach. The cells were yellow-pigmented, rod-shaped, strictly aerobic and devoid of flagella, but showed gliding motility. Strain BLN2 produced yellow, translucent, circular and convex colonies, with optimal growth at 30 °C and pH 7.0. The major respiratory quinone was menaquinone 6 (MK-6) and the predominant fatty acids were iso-C, summed feature 3 (comprising Cω7 and/or Cω6), C 3-OH, C iso-C 3-OH and iso-C 3-OH. The G+C content of the genomic DNA was 34.8 mol%. The 16S rRNA gene sequence analysis showed that strain BLN2 belonged to the genus and was most closely related to CGMCC 1.6859 (97.0 % sequence similarity). The DNA–DNA relatedness between strain BLN2 and CGMCC 1.6859 was 25.7 %. Based on the phenotypic data and phylogenetic inference presented, it is concluded that strain BLN2 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is BLN2 ( = DSM 23314 = CGMCC 1.10370).
