Actinomycete Strain

A novel actinomycete strain, designed MW4-36T, was isolated from tropical forest soil in Nakhon Sawan Province, Thailand. Morphological and chemotaxonomic characteristics of this strain clearly demonstrated that it belongs to the genus Dactylosporangium . The strain formed finger-shaped sporangia on short sporangiophores that emerged directly from substrate hyphae. The cell-wall peptidoglycan contained glutamic acid, glycine, alanine and meso-diaminopimelic acid including 3-hydroxy-meso-diaminopimelic acid; arabinose, glucose, rhamnose, ribose and xylose were found as whole-cell sugars. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol; no phosphatidylcholine was found. The predominant menaquinones were MK-9(H8) and MK-9(H6). Mycolic acids were not detected. The predominant cellular fatty acids were iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The G+C content of the genomic DNA was 72.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences also indicated that the strain should be classified in the genus Dactylosporangium and showed that the closest relative was Dactylosporangium maewongense JCM 15933T (99.4 % similarity). These taxonomic data revealed that strain MW4-36T could be readily distinguished from its phylogenetically closest relative. On the basis of these phenotypic and genotypic data, strain MW4-36T is considered to represent a novel species, for which the name Dactylosporangium siamense sp. nov. is proposed. The type strain is MW4-36T ( = BCC 34901T = NBRC 106093T).

Actinomycete Strain

A novel actinomycete strain, A-T 4600T, which developed cylindrical sporangia containing a longitudinal pair of motile spores forming singly or in bundles on short ramifications of the aerial mycelium, was isolated from soil collected from an evergreen forest in Thailand. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, madurose, mannose and glucose. The predominant menaquinones were MK-9(H2). Mycolic acids were not detected. The diagnostic phospholipids were phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylinositol, phosphatidylglycerol, phosphatidylinositol mannoside, diphosphatidylglycerol and aminophosphoglycolipid. The predominant cellular fatty acids were unsaturated C17 : 1, C18 : 1, saturated C16 : 0, and C17 : 0. The G+C content of the DNA was 70.8 mol%. Phenotypic and chemotaxonomic analyses showed that the isolate had the typical characteristics of members of the genus Planobispora . Furthermore, 16S rRNA gene sequence analysis also indicated that this strain belonged to the genus Planobispora but as a putative novel species. DNA–DNA relatedness values that differentiate the isolate from previously described members of the genus Planobispora were significantly below 70 %. Following an evaluation of phenotypic, chemotaxonomic and genotypic studies, it is proposed that the isolate represents a novel species, Planobispora siamensis sp. nov.; the type strain is A-T 4600T ( = BCC 39469T = NBRC 107568T).

A Gram-staining-positive, aerobic, motile bacterium, designated strain MJ3T, was isolated from myeolchi-jeot (anchovy jeotgal), a traditional fermented seafood in South Korea. Cells were non-endospore-forming cocci showing catalase- and oxidase-positive reactions. Growth of strain MJ3T was observed at 15–45 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.0–8.0) and in the presence of 1–24 % (w/v) NaCl (optimum, 10 % NaCl). Phylogenetic inference based on 16S rRNA gene sequences showed that strain MJ3T formed a tight phyletic lineage with members of the genus Salimicrobium . Strain MJ3T was related most closely to Salimicrobium salexigens 29CMIT, Salimicrobium album DSM 20748T, Salimicrobium flavidum ISL-25T, Salimicrobium luteum BY-5T and Salimicrobium halophilum DSM 4771T, with similarities of 98.8 %, 98.7 %, 98.6 %, 98.4 % and 98.3 %, respectively. However, the DNA–DNA relatedness values between strain MJ3T (KF732837) and S. salexigens DSM 22782T, S. album DSM 20748T, S. flavidum DSM 23127T, S. luteum KCTC 3989T and S. halophilum JCM 12305T were 60±5.4 %, 58.5±6.5 %, 43.6±5.5 %, 37.2±5.8 % and 16.7±0.2 %, respectively. Chemotaxonomic data (sole isoprenoid quinone, MK-7; major cell-wall type, meso-diaminopimelic acid; major cellular fatty acids, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0; major polar lipids, phosphatidylglycerol and diphosphatidylglycerol; DNA G+C content, 46.3 mol%) also supported the affiliation of strain MJ3T with the genus Salimicrobium . Therefore, strain MJ3T represents a novel species of the genus Salimicrobium , for which the name Salimicrobium jeotgali sp. nov. is proposed. The type strain is MJ3T ( = KACC 16972T = JCM 19758T).

Actinomycete Strain

During a bioprospection of bacteria with antimicrobial activity, the actinomycete strain A38T was isolated from a sediment sample of the Carpintero river located in the Gran Piedra Mountains, Santiago de Cuba province (Cuba). This strain was identified as a member of the genus Micromonospora by means of a polyphasic taxonomy study. Strain A38T was an aerobic Gram-positive filamentous bacterium that produced single spores in a well-developed vegetative mycelium. An aerial mycelium was absent. The cell wall contained meso-diaminopimelic acid and the whole-cell sugars were glucose, mannose, ribose and xylose. The major cellular fatty acids were isoC15:0, 10 methyl C17:0, anteiso-C17:0 and iso-C17:0. The predominant menaquinones were MK-10(H4) and MK-10(H6). Phylogenetic analysis of 16S rRNA gene sequences revealed that this strain was closely related to Micromonospora tulbaghiae DSM 45142T (99.5 %), Micromonospora citrea DSM 43903T (99.4 %), Micromonospora marina DSM 45555T (99.4 %), Micromonospora maritima DSM 45782T (99.3 %), Micromonospora sediminicola DSM 45794T (99.3 %), Micromonospora aurantiaca DSM 43813T (99.2 %) and Micromonospora chaiyaphumensis DSM 45246T (99.2 %). The results of OrthoANIu analysis showed the highest similarity to Micromonospora chalcea DSM 43026T (96.4 %). However, the 16S rRNA and gyrB gene sequence-based phylogeny and phenotypic characteristics provided support to distinguish strain A38T as a novel species. On the basis of the results presented here, we propose to classify strain A38T (=LMG 30467T=CECT 30034T) as the type strain of the novel species Micromonospora fluminis sp. nov.

A novel actinomycete, strain FMN03T, was isolated from a soil sample collected from Yuga Zapadnaya South-West Forest Park, Moscow, Russia. The isolate had chemical and morphological properties typical of members of the genus Nonomuraea and formed a distinct 16S rRNA gene subclade with the type strains Nonomuraea roseoviolacea subsp. carminata NBRC 15903T and Nonomuraea roseoviolacea subsp. roseoviolacea NBRC 14098T. The organism formed extensively branched substrate and aerial hyphae, which generated spiral chains of spores with smooth surfaces. The cell wall contained meso-diaminopimelic acid and the whole cell sugars were glucose, galactose and trace amounts of madurose, mannose and xylose. The polar lipids were phosphatidylethanolamine, hydroxyphosphatidylethanolamine, four unidentified phospholipids, four unidentified glycolipids and one unidentified lipid. The predominant menaquinone was MK-9(H4). The major fatty acids were iso-C16 : 0 2-OH, C17 : 0 10-methyl, C17 : 1 cis9 and iso-C16 : 0. Analyses of its morphological, physiological and biochemical characteristics, together with DNA–DNA relatedness data, confirmed that strain FMN03T is a representative of a novel species of the genus Nonomuraea , which is distinct from closely related reference strains. Strain FMN03T ( = DSM 45913T = KCTC 29233T) is proposed as the type strain of a novel species, for which the name Nonomuraea muscovyensis sp. nov. is proposed.
