sp. nov., isolated from cattail root soil from mine tailings.

A yellow-pigmented, Gram-stain-negative, aerobic, non-motile rod shaped, mesophilic bacterium, designated strain N7XX-4, was isolated from cattail root grown on the mine tailings of Phoenix mountain, Tongling city, Anhui Province (PR China). Analysis of the 16S rRNA gene sequence revealed that the strain represented a novel member of the family . The nearest phylogenetic neighbour was MSL-13 (97.8 % 16S rRNA gene sequence similarity). The most abundant fatty acid in whole cells of N7XX-4 was anteiso-C15 : 0 (29.9 %). The predominant menaquinones were MK-12(H), MK-13(H) and MK-11(H). The peptidoglycan type of the isolate was B1δ with l-Lys as the diagnostic cell-wall diamino acid. On the basis of differences in phenotypic and genotypic characteristics, strain N7XX-4 (=CGMCC 1.16548=DSM 106791=JCM 32630) is designated as the type strain of a novel species of the genus , for which the name sp. nov. is proposed.
