Abstract

An orange-coloured bacterium, CCBAU 05354, was isolated from the soybean rhizosphere following growth on NA medium. The sample was taken from a field in Hebei province, People's Republic of China. The cells were aerobic, Gram-stain-negative, short rods (0.4–0.6×0.7–1.7 μm) and non-motile. Growth occurred at 28 °C (not at 10 or 37 °C), pH 6.0–10.0, and in the presence of 0–1 % NaCl (w/v). Flexirubin pigment was produced and the cells were resistant to some antibiotics. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CCBAU 05354 was closely related to KACC 12604 (95.1 % sequence similarity). The predominant cellular fatty acids were iso-C, iso-C G, iso-C 3-OH and summed feature 3 (comprising C 7 and/or C 6). The DNA GC content was 42 mol%. On the basis of the phylogenetic, phenotypic and chemotaxonomic data, strain CCBAU 05354 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is CCBAU 05354 (=LMG 24661 =HAMBI 3031).
