Emended Description

A Gram-stain-negative, non-flagellated, gliding, rod-shaped bacterial strain, designated WT-MY15T, was isolated from wood falls in the South Sea in Korea and subjected to a polyphasic taxonomic study. Strain WT-MY15T grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain WT-MY15T clustered with the type strains of two Olleya species, exhibiting 16S rRNA gene sequence similarity values of 97.7–98.1 %. Strain WT-MY15T contained MK-6 as the predominant menaquinone. The fatty acid and polar lipid profiles of strain WT-MY15T were similar to those of Olleya aquimaris L-4T and Olleya marilimosa CIP 108537T. The DNA G+C content of strain WT-MY15T was 42.8 mol% and its mean DNA–DNA relatedness values with O. aquimaris L-4T and O. marilimosa CIP 108537T were 8.3 and 5.6 %, respectively. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WT-MY15T is separate from the two recognized species of the genus Olleya . On the basis of the data presented, strain WT-MY15T is considered to represent a novel species of the genus Olleya , for which the name Olleya namhaensis sp. nov. is proposed. The type strain is WT-MY15T ( = KCTC 23673T = CCUG 61507T). An emended description of the genus Olleya is also presented.

In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain YCS-9T fell within the family Flavobacteriaceae and formed a cluster with Fulvibacter tottoriensis MTT-39T with a bootstrap resampling value of 75.4 %. Strain YCS-9T showed 92.3 % 16S rRNA gene sequence similarity to F. tottoriensis MTT-39T and 89.0–93.7 % sequence similarity to the other strains used in the phylogenetic analysis. Strain YCS-9T contained MK-6 as the only menaquinone and iso-C15 : 1 G, iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids were one unidentified lipid and one unidentified aminolipid. The DNA G+C content was 34.2 mol%. Strain YCS-9T could be differentiated from F. tottoriensis NBRC 102624T by differences in fatty acid composition, polar lipid profile and some phenotypic properties. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain YCS-9T represents a novel species in a new genus within the phylum Bacteroidetes , for which the name Pseudofulvibacter geojedonensis gen. nov., sp. nov. is proposed.

Strain SB026T was isolated from Brazilian rainforest soil and its taxonomic position established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological features consistent with its classification in the genus Amycolatopsis and formed a branch in the Amycolatopsis 16S rRNA gene tree together with Amycolatopsis bullii NRRL B-24847T, Amycolatopsis plumensis NRRL B-24324T, Amycolatopsis tolypomycina DSM 44544T and Amycolatopsis vancoresmycina NRRL B-24208T. It was related most closely to A. bullii NRRL B-24847T (99.0 % 16S rRNA gene sequence similarity), but was distinguished from this strain by a low level of DNA–DNA relatedness (~46 %) and discriminatory phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the isolate should be classified in the genus Amycolatopsis as representing a novel species, Amycolatopsis rhabdoformis sp. nov. The type strain is SB026T ( = CBMAI 1694T = CMAA 1285T = NCIMB 14900T).
