    Microvirga makkahensis sp nov., and Microvirga arabica sp nov., isolated from sandy arid soil
    (Springer, 2016) Veyisoglu, Aysel; Tatar, Demet; Saygin, Hayrettin; Inan, Kadriye; Cetin, Demet; Guven, Kiymet; Tuncer, Munir
    The taxonomic positions of two Gram-negative strains, SV1470(T) and SV2184P(T), isolated from arid soil samples, were determined using a polyphasic approach. Analysis of the 16S rRNA gene and the concatenated sequences of three housekeeping gene loci (dnaK, rpoB and gyrB) confirmed that the strains belong to the genus Microvirga. Strain SV1470(T) was found to be closely related to Microvirga vignae BR3299(T) (98.8 %), Microvirga flocculans TFBT (98.3 %) and Microvirga lupini Lut6(T) (98.2 %), whilst similarity to other type strains of the genus ranged from 97.8 to 96.3 %; strain SV2184P(T) was found to be closely related to Microvirga aerilata 5420S-16(T) (98.0 %), Microvirga zambiensis WSM3693(T) (97.8 %) and M. flocculans ATCC BAA-817(T) (97.4 %), whilst similarity to other type strains of the genus ranged from 97.2 to 95.9 %. The G + C content of the genomic DNA was determined to be 61.5 mol % for strain SV1470(T) and 62.1 mol % for strain SV2184P(T). Both strains were found to have the same quinone system, with Q-10 as the major ubiquinone. The polar lipid profile of strain SV1470(T) was found to consist of phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified phospholipid and one unidentified aminolipid, while that of strain SV2184P(T) consisted of phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, one unidentified aminolipid, one unidentified aminophospholipid and two unidentified phospholipids. DNA-DNA relatedness studies showed that the two strains belong to different genomic species. The strains were also distinguished using a combination of phenotypic properties. Based on the genotypic and phenotypic data, the novel species Microvirga makkahensis sp. nov. (type strain SV1470(T) = DSM 25394(T) = KCTC 23863(T) = NRRL-B 24875(T)) and Microvirga arabica sp. nov. (type strain SV2184P(T) = DSM 25393(T) = KCTC 23864(T) = NRRL-B 24874(T)) are proposed.

    Phytomonospora cypria sp nov., isolated from soil
    (Springer, 2015) Sahin, Nevzat; Veyisoglu, Aysel; Tatar, Demet; Saygin, Hayrettin; Cetin, Demet; Guven, Kiymet; Klenk, Hans-Peter
    A Gram-stain positive actinobacterial strain, designated KT1403(T), was isolated from a soil sample, collected from Karpaz, Magusa, Northern Cyprus, and characterised using a polyphasic approach. Morphological characteristics and chemotaxonomic data indicated that the strain belongs to the genus Phytomonospora. The cell wall of the novel strain contained meso-diaminopimelic acid and galactose, glucose and mannose as the major sugars in whole cell hydrolysates. The polar lipids in the cell membrane were identified as diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, an unidentified aminophospholipid and three unidentified glycolipids. The predominant menaquinones were MK-10(H-6) and MK-10(H-4). The major fatty acids were found to be iso C-15:0 , anteiso C-15:0 and anteiso C-17:0. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain KT1403(T) belongs to the genus Phytomonospora with a sequence similarity of 99.73 % with Phytomonospora endophytica, the type species of the genus. DNA-DNA hybridization further differentiated strain KT1403(T) from its near phylogenetic neighbour, P. endophytica DSM 45386(T) (29.0 +/- A 2.2 % DNA relatedness). Therefore, it is proposed that strain KT1403(T) represents a novel species of the genus Phytomonospora, for which the name Phytomonospora cypria sp. nov. is proposed. The type strain is KT1403(T) (=KCTC 29479(T) = DSM 46767(T)).

    (Springer, 2017) Veyisoglu, Aysel; Saygin, Hayrettin; Tatar, Demet; Bektas, Kadriye Inan; Sahin, Nevzat
    A Saccharopolyspora strain, designated CR3506(T), isolated from a soil sample collected from Sungurlu, Corum, Turkey, was examinated using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence analysis showed that the strain is closely related to the type strains of Saccharopolyspora spinosa NRRL 18395(T) (99.1%), Saccharopolyspora phatthalungensis NRRL B-24798(T) (98.4%) and Saccharopolyspora shandongensis 88(T) (98.1%); low levels of DNA-DNA relatedness were found between the isolate and S. spinosa and S. phatthalungensis (< 50%). Strain CR3506(T) was found to have chemotaxonomic and phylogenetic properties consistent with its classification in the genus Saccharopolyspora. The strain contained meso-diaminopimelic acid as the diagnostic diamino acid. Whole-cell hydrolysates contained arabinose and galactose. The polar lipids were identified as phosphatidylmethylethanolamine, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol and phosphatidylinositol. The predominant menaquinones (> 10%) were MK-9(H-4) and MK-8(H-4). Major fatty acids were (> 10%) iso-C-16:0, C(15:0)3OH, C-18:0 and iso-C-15:0. Further, the morphological, physiological and biochemical characteristics of strain CR3506(T) are distinct from S. spinosa and other species of the genus Saccharopolyspora with which this strain has high 16S rRNA gene sequence similarity (98.0-98.5%). Strain CR3506(T) has antimicrobial activity against Bacillus subtilis NRRL B-209, Citrobacter freundi NRRL B-2643 and Staphylococcus aureus ATCC 29213. Consequently, it is proposed that strain CR3506(T) represents a novel Saccharopolyspora species for which the name Saccharopolyspora hattusasensis sp. nov. is proposed. The type strain is CR3506(T) (=KCTC 29104(T) = DSM 45715(T)).

    (Microbiology Soc, 2020) Saygin, Hayrettin; Veyisoglu, Aysel; Tatar, Demet; Nigiz, Cengiz; Tokatli, Ali; Sahin, Nevzat
    A novel actinobacteria, isolate A7024(T), was isolated from commercial hazelnut orchard soil sample which was collected at Duzce, West Black Sea region, Turkey. A polyphasic taxonomic study was carried out to determine the status of this isolate. The phylogenetic tree reconstructed using the neighbour-joining algorithm based on 165 rRNA gene sequences indicated that isolate A7024(T) was positioned within the members of the genus Streptomyces with the highest sequence similarity (97.7%) to Streptomyces cadmiisoli ZFG47(T). The organism formed an extensively branched substrate and aerial hyphae which generated irregular rod-shaped spores with smooth-surfaces. The cell wall of strain A7024(T) contained LL-diaminopimelic. Glucose, mannose and ribose were detected as whole-cell sugars. Its polar lipids were diphosphatidylglycerol. phosphatidylethanol-amine, phosphatidylinositol, three unidentified phospholipids and three unidentified glycolipids. Major menaquinones were MK-9(H-6) and MK-9(H-4). The major cellular fatty acids were iso-C-16:0, anteiso-C-1(5:0) and anteiso-C-1(7:)0. Strain A7024(T) had a genome size of 9.0 Mb with a genome G+C content of 71.5 mol%. The low level of 16S rRNA gene similarity, 19.3 +/- 2.3% digital DNA-DNA-hybridization and 76.94% average nucleotide identity values, as well as some different phenotypic characteristics allowed the strain to be distinguished from the closely related type strains. Therefore, it is concluded that strain A7024(T) represents a novel species of the genus of Streptomyces, for which the name Streptomyces coryli sp. nov. is proposed. The type strain is A7024(T) (=DSM 42066(T)=KCTC 29102(T)=NRRL B-24888(T)).
