An actinomycete, strain RI109-Li102T, was isolated from a lichen sample obtained from Rishiri Island in Japan. Cells of strain RI109-Li102T were Gram-positive, aerobic and non-motile and formed bud-like spore chains. The isolate grew with 0–3 % (w/v) NaCl, at pH 5–9 and at 10–30 °C (optimum 30 °C). The whole-cell hydrolysate contained meso-diaminopimelic acid, arabinose and galactose. The predominant menaquinone was MK-8(H4) and the diagnostic phospholipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were iso-C16 : 0 and iso-C16 : 1 H. Comparative 16S rRNA gene sequence analysis revealed that strain RI109-Li102T was most closely related to Actinomycetospora corticicola 014-5T (99.0 % rRNA gene sequence similarity) and Actinomycetospora chiangmaiensis YIM 0006T (98.4 %). However, DNA–DNA hybridization assays, as well as physiological and biochemical analyses, showed that strain RI109-Li102T could be differentiated from its closest phylogenetic relatives. It is proposed that strain RI109-Li102T ( = NBRC 106356T  = KCTC 19782T) be classified as the type strain of a novel species, with the name Actinomycetospora rishiriensis sp. nov.

Strain T5-04T, a Gram-negative, non-spore-forming, rod-shaped bacterium, was isolated from soil of a ginseng field in South Korea and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain T5-04T belongs to the α-4 subgroup of the Proteobacteria, and the highest degrees of sequence similarity determined were to Sphingomonas asaccharolytica IFO 10564T (97·5 %), Sphingomonas koreensis JSS26T (97·1 %), Sphingomonas mali IFO 15500T (96·7 %) and Sphingomonas pruni IFO 15498T (96·6 %). Chemotaxonomic data revealed that strain T5-04T possesses ubiquinone Q-10 predominantly, C18 : 1 as the predominant fatty acid and sphingoglycolipids, all of which corroborate its assignment to the genus Sphingomonas. The results of DNA–DNA hybridization and physiological and biochemical tests clearly demonstrated that strain T5-04T represents a distinct species. Based on polyphasic evidence, T5-04T (=KCTC 12210T=NBRC 100801T=IAM 15213T) should be classified as the type strain of a novel Sphingomonas species, for which the name Sphingomonas soli sp. nov. is proposed.

A thermophilic strain, designated YIM 10002T, was isolated from a soil sample of Big Empty Volcano in Tengchong county, Yunnan province, south-west China, and a polyphasic approach was used to investigate its taxonomic position. Strain YIM 10002T formed endospores on both aerial and substrate mycelia. Whole-cell hydrolysates contained meso-diaminopimelic acid, ribose, xylose and glucose. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The predominant menaquinone was MK-9. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannosides, together with some unknown phospholipids. The G+C content of its genomic DNA was 48.6 mol%. All of these chemotaxonomic data together with morphological characters consistently assigned strain YIM 10002T to the genus Laceyella. 16S rRNA gene sequence analysis showed that strain YIM 10002T was most closely related to Laceyella sacchari KCTC 9790T and Laceyella putida KCTC 3666T (99.9 and 98.0 % 16S rRNA gene sequence similarity, respectively). However, strain YIM 10002T showed relatively low DNA–DNA relatedness (34.0 and 39.0 %, respectively) with the above strains. Therefore, strain YIM 10002T represents a novel species of the genus Laceyella, for which the name Laceyella tengchongensis sp. nov. is proposed. The type strain is YIM 10002T (=DSM 45262T =CCTCC AA 208050T).

A novel actinomycete, strain ST1-08T, was isolated from the stem of Stemona sp. in Thailand. The taxonomic position of this isolate was determined by using a polyphasic approach. Strain ST1-08T contained meso-diaminopimelic acid in the cell-wall peptidoglycan, and arabinose and galactose as diagnostic sugars of the whole-cell hydrolysate, which are typical properties of members of the genus Amycolatopsis. Strain ST1-08T grew at 15–40 °C, pH 6–9 and on 5 % (w/v) NaCl. Gelatin liquefaction, starch hydrolysis and skimmed milk peptonization were positive. The strain utilized l-arabinose, d-glucose, glycerol, myo-inositol, d-mannitol and l-rhamnose. The predominant menaquinone was MK-9(H4) and the major cellular fatty acids were iso-C16 : 0 and iso-C15 : 0.The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyl-phosphatidylethanolamine, phosphatidylinositol and phosphatidylglycerol. The 16S rRNA gene sequence analysis revealed that the strain was closely related to Amycolatopsis pretoriensis JCM 12673T (98.99 %) and Amycolatopsis lexingtonensis JCM 12672T (98.87 %). The DNA G+C content of strain ST1-08T was 71.2 mol%. The DNA–DNA relatedness values among strain ST1-08T, A. pretoriensis JCM 12673T and A. lexingtonensis JCM 12672T were lower than 70 %, the cut-off level for assigning strains to the same species. On the basis of phenotypic and genotypic characteristics, strain ST1-08T represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis stemonae is proposed. The type strain is ST1-08T( = JCM 30050T = PCU 339T = TISTR 2278T).
