F.YR 2009 T1 Azospirillum picis sp. nov., isolated from discarded tar JF International Journal of Systematic and Evolutionary Microbiology, VO 59 IS 4 SP 761 OP 765 DO https://doi.org/10.1099/ijs.0.65837-0 PB Microbiology Society, SN 1466-5034, AB A polyphasic taxonomic study was performed on a pink-coloured unknown bacterium isolated from discarded road tar. Comparative analysis of the 16S rRNA gene sequence demonstrated that the isolate belongs phylogenetically to the genus Azospirillum with Azospirillum lipoferum, A. melinis and A. rugosum as its closest phylogenetic relatives (96.7, 96.6 and 96.6 % similarity to the respective type strains). The generic assignment was confirmed on the basis of chemotaxonomic data, which revealed a fatty acid profile characteristic for the genus Azospirillum, consisting of straight-chain saturated and unsaturated fatty acids, with C18 : 1 ω7c as the major unsaturated non-hydroxylated fatty acid, and C16 : 0 3-OH as the major hydroxylated fatty acid, and a ubiquinone with ten isoprene units (Q-10) as the predominant respiratory quinone. On the basis of both the phenotypic and molecular genetic evidence, it is proposed that the unknown isolate should be classified within a novel species of the genus Azospirillum, for which the name Azospirillum picis sp. nov. is proposed. The type strain is IMMIB TAR-3T (=CCUG 55431T =DSM 19922T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65837-0
