Actinomycete Strain

An actinomycete strain, designated strain SH2-13T, was isolated from a marine sediment sample collected from the Andaman Sea of Thailand. Applying a polyphasic approach, the isolate was identified as a member of the genus Micromonospora using morphological and chemotaxonomic characteristics, including the presence of meso-diaminopimelic acid in the peptidoglycan. Whole-cell sugars were arabinose, galactose, glucose, rhamnose, ribose and xylose. Diagnostic polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and phosphoglycolipids. The major menaquinones were MK-10(H2), MK-10(H4) and MK-10(H6). 16S rRNA gene sequence analysis revealed similarity to Micromonospora marina JSM1-1T (99.1 %), Micromonospora coxensis 2-30-b(28)T (99.1 %), Micromonospora aurantiaca DSM 43813T (98.8 %) and Micromonospora chalcea DSM 43026T (98.7 %). However, a combination of DNA–DNA hybridization results and phenotypic properties indicated that strain SH2-13T ( = NBRC 107934T = BCC 45601T) should be classified as the type strain of a novel species, with the proposed name Micromonospora sediminicola sp. nov.

A facultatively alkaliphilic actinomycete strain, designated EGI 80088T, was isolated from a saline-alkali soil sample from Xinjiang province, north-west China, and subjected to a polyphasic taxonomic characterization. Strain EGI 80088T formed fragmented aerial hyphae and short spore chains, and rod-like spores aggregated at maturity. Whole-cell hydrolysates of the isolate contained ll-diaminopimelic acid as the diagnostic diamino acid, and glucosamine, mannose, galactose, glucose and rhamnose as the marker sugars. The major fatty acids identified (>5 %) were anteiso-C15 : 0, iso-C15 : 0, summed feature 4 (iso-C17 : 1I/anteiso-C17 : 1B), iso-C16 : 0 and anteiso-C17 : 0. The predominant menaquinone was MK-9(H4). The G+C content of the genomic DNA of strain EGI 80088T was 70.6 mol%. EGI 80088T showed the highest 16S rRNA gene sequence similarity to its closest phylogenetic neighbour Haloactinopolyspora alba YIM 93246T (98.5 %). The DNA–DNA relatedness value of the strain EGI 80088T and H. alba YIM 93246T was 59.3±5.2 %. On the basis of morphological, chemotaxonomic and phylogenetic characteristics and DNA–DNA hybridization data, strain EGI 80088T represents a novel species of the genus Haloactinopolyspora , for which the name Haloactinopolyspora alkaliphila sp. nov. (type strain EGI 80088T = BCRC 16946T = JCM 19128T) is proposed. The description of the genus Haloactinopolyspora has also been emended.

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.

Actinomycete Strain

A novel actinomycete, strain DS3030T, was isolated from a deep sediment sample, collected from the southern Black Sea coast, Turkey, and was examined using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain DS3030T was shown to belong to the genus Saccharomonospora and to be related most closely to Saccharomonospora marina XMU15T (99.6 % similarity). Sequence similarities with other strains of the genus Saccharomonospora were lower than 97.0 %. The organism had chemical and morphological features typical of the genus Saccharomonospora . The cell wall of the novel strain contained meso-diaminopimelic acid, arabinose and galactose as diagnostic sugars. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The predominant menaquinone was MK-9(H4). Major fatty acids were iso-C16 : 0, iso-C16 : 0 2-OH and C16 : 1 cis 9. Phenotypic data clearly distinguished the new isolate from its closest relative, S. marina XMU15T. The combined genotypic and phenotypic data and low DNA–DNA relatedness with its closest related strain reveal that strain DS3030T represents a novel species of the genus, for which the name Saccharomonospora amisosensis sp. nov. is proposed. The type strain is DS3030T ( = DSM 45685T = KCTC 29069T = NRRL B-24885T).

A novel actinomycete, designated strain ASG 168T, was isolated from cave rock collected from Stegodon Sea Cave in Thailand. Long chains of non-motile spores that were oval or spherical in shape with a smooth surface developed on aerial mycelia. Substrate mycelia fragmented into irregular rod-shaped elements. A polyphasic taxonomic study showed that strain ASG 168T had typical characteristics of members of the genus Prauserella . 16S rRNA gene sequence analysis indicated that strain ASG 168T shared 97.5 % similarity with Prauserella marina MS498T and 96.7 % with Prauserella coralliicola SCSIO 11529T. Average nucleotide identity values with P. coralliicola SCSIO 11529T and P. marina MS498T were 82.98 and 76.08 %, respectively. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, arabinose and galactose. The predominant menaquinone was MK-9(H4). The predominant fatty acids were iso-C16 : 0, C16 : 0 and summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c). The phospholipid profile consisted of phosphatidylethanolamine, phosphatidylmethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and two unknown phospholipids. The G+C content of the genomic DNA was 70.6 mol%. Differentiation of strain ASG 168T from closely related species was evident from digital DNA–DNA hybridization values of 29.2 and 21.3 % with P. coralliicola and P. marina , respectively. Based on comparative analysis of phenotypic, chemotaxonomic and genotypic data, the novel actinomycete strain ASG 168T (=TBRC 13679T=NBRC 114887T) is proposed to be the type strain of a novel species, Prauserella cavernicola sp. nov.
