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).

Abstract The moderately halophilic, Gram-stain-positive, spore-forming rods, designated SKP4-8T and SKP8-2T isolated from a traditional fermented shrimp paste (Ka-pi), were taxonomic studied based on polyphasic approach. Strain SKP4-8T grew at pH 6.0-9.0 (optimum 7.0), at 25-45°C (optimum 37°C) and in 1-16 % (w/v) NaCl (optimum 5-10). Strain SKP8-2T grew at pH 6.0-9.0 (optimum 8.0), at 25-45°C (optimum 37°C) and in 0-20 % (w/v) NaCl (optimum 3-10 %). The strains contained meso-diaminopimelic acid in cell-wall peptidoglycan and the major menaquinone was MK-7. Strain SKP4-8T contained iso-C15:0, antesio-C15:0 and iso-C17:0; and strain SKP8-2T contained antesio-C15:0, iso-C15:0, iso-C16:0 and antesio-C17:0 as major cellular fatty acids.Phosphatidylglycerol, diphosphatidylglycerol, unknown phospholipids and an unknown glycolipid were detected as major polar lipids. On the basis of 16S rRNA gene sequence analysis, strains SKP4-8T and SKP8-2T belonged to the genus Allobacillus and was closely related to Allobacillus halotolerans LMG 24826T with 98.8 % and 99.3 % similarity, respectively. The comparative genome analysis based on average nucleotide identity (ANI) and digital DNA-DNA hybridization revealed that both strains showed the values below 95 and 70 %, from each other and the Allobacillus halotolerans LMG 24826T, respectively. Based on data from this polyphasic study, strains SKP4-8T and SKP8-2T represent the novel species of the genus Allobacillus and the name Allobacillus salarius sp. nov. was proposed for SKP4-8T (=KCTC 33905T =LMG 30016T =TISTR 2499T); and Allobacillus saliphilus sp. nov. for SKP8-2T (=KCTC 33906T =LMG 29682T =TISTR 2558T).

In 2001, a Gram-variable, facultatively anaerobic, endospore-forming bacterium isolated from biodeteriorated mural paintings in the Servilia tomb of the Roman necropolis of Carmona was deposited as Paenibacillus strain LMG 19508. Subsequently, the strain was characterized in detail using phenotypic and molecular methods. The 16S rRNA gene sequence confirmed that the strain belongs to the genus Paenibacillus and indicated its relationship to Paenibacillus mendelii CCM 4839T (96.7 % sequence similarity). The predominant menaquinone was MK-7. The cell wall contained meso-diaminopimelic acid of the A1γ type. The DNA G+C content (50 mol%) and the major fatty acid (anteiso-C15 : 0) of strain LMG 19508T were also consistent with its affiliation to the genus Paenibacillus. DNA–DNA hybridization distinguished strain LMG 19508T from other phylogenetically related Paenibacillus species. Therefore, the isolate represents a novel species, for which the name Paenibacillus sepulcri sp. nov. is proposed. The type strain is CCM 7311T (=LMG 19508T).

An actinomycete that developed sporangia containing four spores in a single row at the ends of short sporangiophores on branched aerial hyphae was isolated from subtropical forest soil. The isolate contained menaquinone MK-9(H4), glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and madurose in the whole-cell hydrolysate. The 16S rRNA gene sequence indicated that the isolate formed a monophyletic cluster with Planotetraspora mira. On the basis of morphological and chemotaxonomic characteristics, phylogenetic analysis and DNA–DNA relatedness data, a novel species of the genus Planotetraspora is proposed, Planotetraspora silvatica sp. nov. (type strain, TT 00-51T=NBRC 100141T=DSM 44746T).

The isolate grew optimally at 20–30 °C and pH 7.3–7.8. Comparative analysis of the 16S rRNA gene sequence showed that isolate XJ259T belonged phylogenetically to the genus Paenibacillus, and was most closely related to Paenibacillus xinjiangensis B538T (with 96.6 % sequence similarity), Paenibacillus glycanilyticus DS-1T (96.3 %) and Paenibacillus castaneae Ch-32T (96.1 %), sharing less than 96.0 % sequence similarity with all other members of the genus Paenibacillus. Chemotaxonomic analysis revealing menaquinone-7 (MK-7) as the major isoprenoid quinone, diphosphatidylglycerol, phosphatidylethanolamine and two unknown phosphoglycolipids as the major cellular polar lipids, a DNA G+C content of 47.0 mol%, and anteiso-C15 : 0 and C16 : 0 as the major fatty acids supported affiliation of the new isolate to the genus Paenibacillus. Based on these data, isolate XJ259T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus algorifonticola sp. nov. is proposed. The type strain is XJ259T ( = CGMCC 1.10223T  = JCM 16598T).
