Lysobacter dokdonensis sp. nov., isolated from soil.
ABSTRACT A Gram-negative, non-motile, rod-shaped bacterial strain, DS-58(T), was isolated from a soil sample from Dokdo, an island of Korea, and its taxonomic position was investigated. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-58(T) fell within the family Xanthomonadaceae. The isolate showed 96.9 % 16S rRNA gene sequence similarity with its closest phylogenetic neighbour, Lysobacter niastensis GH41-7(T), and 93.4-95.7 % 16S rRNA gene sequence similarity with other members of the genus Lysobacter. Strain DS-58(T) contained Q-8 as the predominant ubiquinone and iso-C(16 : 0), iso-C(15 : 0) and iso-C(17 : 1)ω9c as the major fatty acids. The DNA G+C content was 68.1 mol%. Strain DS-58(T) could be distinguished phenotypically from type strains of closely related species of the genus Lysobacter and phylogenetically from all members of the genus Lysobacter. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain DS-58(T) is considered to represent a novel species of the genus Lysobacter, for which the name Lysobacter dokdonensis sp. nov. is proposed. The type strain is DS-58(T) ( = KCTC 12822(T) = DSM 17958(T)).

ABSTRACT: The 16S rDNAs from 38 strains of the genus Nocardioides, two Aeromicrobium species and Terrabacter tumescens were directly sequenced and then analysed. The mean nucleotide similarity value between the type strains of validly described Nocardioides species was 96.1 +/- 3.0%. The mean nucleotide similarity value between the type strains of validly described Nocardioides species and the two Aeromicrobium species was 93.7 +/- 1.4% T. tumescens was distantly related to the genera Nocardioides and Aeromicrobium. The mean intraspecific nucleotide similarity value of 16S rDNA sequences from Nocardioides albus was 99.5 +/- 0.5%. The mean intraspecific nucleotide similarity of 16S rDNA sequences from Nocardioides simplex was 100%, except for N. simplex strains ATCC 13260, ATCC 19565 and ATCC 19566, which were shown not to be members of the genus Nocardioides. 'Nocardioides flavus' strains IFO 14396T and IFO 14397, and 'Nocardioides fulvus' JCM 3335T showed a 16S rDNA similarity value of 100% with Nocardioides luteus KCTC 9575T and Nocardioides albus JCM 5854. 'N. fulvus' IFO 14399 shared its highest 16S rDNA similarity with Nocardioides sp. ATCC 39419 at 99%. 'N. fulvus' IFO 14399 and Nocardioides sp. ATCC 39419 formed a phylogenetic lineage distinct from the genera Nocardioides and Aeromicrobium. 'Nocardioides thermolilacinus' strains IFO 14335T and IFO 14336 displayed a close relationship to the genus Streptomyces. From 16S rDNA sequence analyses, it is considered that some strains that have been attributed to the genus Nocardioides should be taxonomically re-evaluated.International journal of systematic bacteriology 01/1998; 48 Pt 1:187-94. · 2.27 Impact Factor
