<Emphasis Type="Italic">Saccharopolyspora lacisalsi</Emphasis> sp. nov., a novel halophilic actinomycete isolated from a salt lake in Xinjiang,China

A novel actinomycete strain, designated TRM 40133^T, was isolated from a hypersaline habitat of Tarim basin in Xinjiang Province, north-west China. Its taxonomic status was determined using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of the strain showed that it formed a well-seperated sub-branch within the radiation of the genus Saccharopolyspora. The highest levels of 16S rRNA gene sequence similarity was found between the strain TRM 40133^T and Saccharopolyspora qijiaojingensis YIM 91168^T (96.5%). The chemotaxonomic characteristics of the isolate are typical for the genus Saccharopolyspora. It contained meso-DAP as the diagnostic diamino acid. Whole cell hydrolysate contained arabinose, xylose, ribose and glucose. The diagnostic phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and two unknown phospholipids. The main menaquinone was MK-9(H₆) and MK-9(H₄). No mycolic acid was detected. The predominant cellular fatty acids were iso-C_16:0 and anteiso-C_17:0. The G+C content of the genomic DNA was 68.2 mol%. In addition, the strain TRM 40133^T had a phenotypic profile that readily distinguished it from the recognized representatives of the genus Saccharopolyspora. The strain TRM 40133^T therefore represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora lacisalsi sp. nov. is proposed. The type strain is TRM 40133^T (=KCTC 19987^T =CCTCC AA 2010012^T).     

<Emphasis Type="Italic">Streptomyces carminius</Emphasis> sp. nov., a novel actinomycete isolated from <Emphasis Type="Italic">Sophora alopecuroides</Emphasis> in Xinjiang,China

A novel actinobacterial strain, designated TRM SA0054^T, was isolated from the roots of Sophora alopecuroides grown in Alar, Xinjiang, north-west China, and characterised by a polyphasic taxonomic approach. Phylogenetic analysis showed that strain TRM SA0054^T has 16S rRNA gene sequence similarity of 98.22% with Streptomyces barkulensis RC 1831^T. Whole cell hydrolysates of strain TRM SA0054^T were found to contain ll-diaminopimelic acid as the diagnostic diamino acid and ribose, glucose and xylose as the major whole cell sugars. The major fatty acids were identified as iso-C_16:0, iso-C_16:1 G, anteiso-C_17:0, anteiso-C_15:0, C_16:0, anteiso-C_17:1 ω9c. The main menaquinones were determined to be MK-8 (H₄), MK-9 (H₆) and MK-9 (H₈). The polar lipids were identified as diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol, phosphatidylinositol mannoside and an unidentified lipid. The G?+?C content of the genomic DNA was determined to be 73.04%. Strain TRM SA0054^T has a relatively low DNA–DNA relatedness value with Streptomyces barkulensis RC 1831^T as determined by calculating the average nucleotide identity value (ANI?=?84.1%). Based on the phenotypic, chemotaxonomic and phylogenetic data, it is concluded that strain TRM SA0054^T should be designated as a novel species of the genus Streptomyces, for which the name Streptomyces carminius sp. nov. is proposed, with type strain TRM SA0054^T (=?CCTCC AA 2016041^T?=?KCTC39903^T).     

<Emphasis Type="Italic">Actinokineospora</Emphasis><Emphasis Type="Italic">mzabensis</Emphasis> sp. nov., a novel actinomycete isolated from Saharan soil

A novel actinomycete strain, designated PAL84, was isolated from a Saharan soil sample collected from Béni-Isguen, Ghardaïa (South of Algeria). This strain was studied for its taxonomic position using a polyphasic approach and was identified as a member of the genus Actinokineospora. Phylogenetic analysis showed that strain PAL84 had 16S rRNA gene sequence similarities with members of the genus Actinokineospora ranging from 96.2 % (Actinokineospora inagensis DSM 44258^T) to 97.8 % (Actinokineospora baliensis NBRC 104211^T). The strain was observed to produce pinkish-purple aerial mycelium and purplish red substrate mycelium, which fragmented readily into chains of non-motile elements. The optimum growth temperature and pH were found to be 25–30 °C and 5.0–7.0, respectively. The cell-wall hydrolysate of strain PAL84 was found to contain meso-diaminopimelic acid and the diagnostic whole-cell sugars were identified as arabinose and galactose. The predominant menaquinone was identified as MK-9 (H₄). The major fatty acids were found to be iso-C_16:0, iso-C_15:0, iso-C_16:1 H and iso-C_16:0 2OH. The diagnostic phospholipid detected was phosphatidylethanolamine. The genotypic and phenotypic data show that the strain represents a novel species of the genus Actinokineospora, for which the name Actinokineospora mzabensis sp. nov. is proposed, with the type strain PAL84^T (=DSM 45961^T = CECT 8578^T).     

<Emphasis Type="Italic">Promicromonospora viridis</Emphasis> sp. nov., a novel actinomycete isolated from soil

Two Gram-stain positive, aerobic actinomycete strains, designated NEAU-JGR1^T and NEAU-JGC41, were isolated from soil collected from Fairy Lake Botanical Garden in Shenzhen, Guangdong Province, south of China. The 16S rRNA gene sequences analysis showed that the two strains exhibited 99.5% 16S rRNA gene sequence similarity with each other and were closely related to Promicromonospora thailandica JCM 17130^T (99.4, 99.3%) and Promicromonospora citrea DSM 43110^T (99.2, 99.2%). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the two strains clustered together and formed a cluster with P. thailandica JCM 17130^T and P. citrea DSM 43110^T. Both strains were observed to contain MK-9(H₄) and MK-9(H₂) as predominant menaquinones. Their whole cell sugar profiles were found to main contained rhamnose, ribose, glucose and galactose. The phospholipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycophosphatidylinositol, phosphatidylinositol mannoside, an unidentified glycolipid and an unidentified phospholipid. The predominant cellular fatty acids for the two strains were identified as anteiso-C_15:0, iso-C_15:0 and anteiso-C_17:0. The DNA–DNA hybridization value between strains NEAU-JGR1^T and NEAU-JGC41 was 85.1?±?0.3%, and the values between the two strains and their close phylogenetic relatives were well below 70%, supporting the conclusion that they represent a distinct genomic species. An array of phenotypic characteristics also differentiated the isolates from closely related species. On the basis of the genetic and phenotypic properties, strains NEAU-JGR1^T and NEAU-JGC41 can be classified as representatives of a novel species of the genus Promicromonospora, for which the name Promicromonospora viridis sp. nov., is proposed. The type strain is NEAU-JGR1^T (=?DSM 105536^T?=?CGMCC 4.7473^T).     

<Emphasis Type="Italic">Streptomyces xiangluensis</Emphasis> sp. nov., a novel actinomycete isolated from soil

A novel actinomycete, designated strain NEAU-LA29^T, was isolated from soil collected from Xianglu Mountain and subjected to a polyphasic taxonomic study. Based on a polyphasic taxonomic approach comprising chemotaxonomic, phylogenetic, morphological and physiological characterisation, the isolate has been affiliated to the genus Streptomyces. 16S rRNA gene sequence analysis showed that the isolate is closely related to Streptomyces vastus JCM4524^T (98.8% identity) and Streptomyces cinereus DSM43033^T (97.9%). However, multilocus sequence analysis based on five other house-keeping genes (atpD, gyrB, rpoB, recA and trpB) and low DNA–DNA relatedness values enabled the strain to be differentiated from these closely related species of the genus Streptomyces. Thus, strain NEAU-LA29^T is concluded to represent a novel species of the genus Streptomyces, for which the name Streptomyces xiangluensis sp. nov. is proposed. The type strain is NEAU-LA29^T (=?CGMCC 4.7466^T?=?DSM 105786^T).     

<Emphasis Type="Italic">Halomonas qijiaojingensis</Emphasis> sp. nov. and <Emphasis Type="Italic">Halomonas flava</Emphasis> sp. nov., two moderately halophilic bacteria isolated from a salt lake

Two moderately halophilic, Gram-negative, rod-shaped bacteria, designated YIM 93003^T and YIM 94343^T, were isolated from a salt lake in Xinjiang province, north-west China. The two strains YIM 93003^T and YIM 94343^T grew at 20–40°C, pH 6–9, 0.5–24% (w/v) NaCl and at 20–40°C, pH 6–9, 0.5–23% (w/v) NaCl, respectively. No growth occurred in absence of NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains YIM 93003^T and YIM 94343^T were phylogenetically affiliated to the genus Halomonas and exhibited sequence similarity of 97.5% and 97.4% to the type strain Halomonas anticariensis DSM 16096^T, respectively. The strains possessed chemotaxonomic markers that were consistent with their classification in the genus Halomonas (Q-9 as predominant respiratory quinine; C18:1ω7c, C16:0 and C16:1 ω7c/iso-C15:02-OH as the major fatty acids). The DNA–DNA hybridization values for strains YIM 93003^T and YIM 94343^T, YIM 93003^T and DSM 16096^T, YIM 94343^T and DSM 16096^T were 38.1 ± 3.0, 18.3 ± 4.7, and 20.8 ± 4.6%, respectively. The G+C contents of the strains YIM 93003^T and YIM 94343^T were 63.4 and 64.0 mol%, respectively. Based on comparative analysis of physiological, biochemical and chemotaxonomic data, including low DNA–DNA hybridization results, two novel species, Halomonas qijiaojingensis sp. nov., and Halomonas flava sp. nov., are proposed. The type strains are YIM 93003^T (=CCTCC AB 208133^T =KCTC 22228^T) and YIM 94343^T (=CCTCC AB 2010382^T =KCTC 23356^T), respectively.

DNA–DNA hybridization and comparison of physiological and chemical characteristics suggested that strain YIM 60475^T is a new Streptomyces species, for which the name Streptomyces mayteni sp. nov. is proposed. The type strain is YIM 60475^T (=CCTCC AA 207005^T = KCTC 19383^T). Hua-Hong Chen and Sheng Qin contributed equally to this work.     

<Emphasis Type="Italic">Flavobacterium koreense</Emphasis> sp. nov., <Emphasis Type="Italic">Flavobacterium chungnamense</Emphasis> sp. nov., and <Emphasis Type="Italic">Flavobacterium cheonanense</Emphasis> sp. nov., isolated from a freshwater reservoir

Taxonomic studies were performed on three strains isolated from Cheonho reservoir in Cheonan, Korea. The isolates were Gram-negative, aerobic, rod-shaped, non-motile, catalase-positive, and oxidase-positive. Colonies on solid media were cream-yellow, smooth, shiny, and circular. Phylogenetic analysis of the 16S rRNA gene sequences revealed that these strains belong to the genus Flavobacterium. The strains shared 98.6–99.4% sequence similarity with each other and showed less than 97% similarity with members of the genus Flavobacterium with validly published names. The DNA-DNA hybridization results confirmed the separate genomic status of strains ARSA-42^T, ARSA-103^T, and ARSA-108^T. The isolates contained menaqui-none-6 as the predominant menaquinone and iso-C_15:0, iso-C_15:0 3-OH, iso-Ci_15:1 G, and iso-C_16:0 3-OH as the major fatty acids. The genomic DNA G+C content of the isolates were 31.4–33.2 mol%. According to the phenotypic and genotypic data, these organisms are classified as representative of three novel species in the genus Flavobacterium, and the name Flavobacterium koreense sp. nov. (strain ARSA-42^T =KCTC 23182^T =JCM 17066^T =KACC 14969^T), Flavobacterium chungnamense sp. nov. (strain ARSA-103^T =KCTC 23183^T =JCM 17068^T =KACC 14971^T), and Flavobacterium cheonanense sp. nov.

<Emphasis Type="Italic">Streptomyces roseoalbus</Emphasis> sp. nov., an actinomycete isolated from soil in Yunnan,China

A strain YIM 33098T (= CCTCC AA001027T = DSM 41831T) was isolated from a forest soil sample collected from Nanning in Guangxi Province, China, in the course of screening for producers of new drug lead compounds. This strain was identified by using a polyphasic approach. The results showed that it should be assigned to the genus Streptomyces. An almost complete 16S rRNA gene sequence of the strain was determined and compared with those of representative Streptomyces species. Strain YIM 33098T was clustered in the same subclade with Streptomyces tendae ATCC19812T and Streptomyces eurythermus ATCC14975T. Similarities of strain YIM 33098T with the two strains were 97.35% and 97.42%, respectively. Based on the phenotypic and genotypic evidence, it is therefore proposed that strain YIM 33098T should be classified in the genus Streptomyces as a new species under the name of Streptomyces nanningensis sp. nov.     

<Emphasis Type="Italic">Glycomyces halotolerans</Emphasis> sp. nov., a novel actinomycete isolated from a hypersaline habitat in Xinjiang,China

A novel actinomycete strain, designated TRM 40137^T, was isolated from a hypersaline habitat in Xinjiang Province, north-west China, and subjected to a polyphasic taxonomic study. The strain was aerobic, Gram-positive and the optimum NaCl concentration for growth was 4–5% (w/v). Phylogenetic analysis showed that strain TRM 40137^T has a 16S rRNA gene sequence similarity of 95.02% with the described species Glycomyces sambucus E71^T and can be distinguished from all previously described representatives of the genus Glycomyces. The whole-cell sugar pattern consisted of xylose and galactose. The predominant menaquinone was MK-10(H₂) and the major fatty acids were anteiso-C15:0 and anteiso-C17:0. The phospholipid pattern consists of phosphatidylglycerol, diphosphatidylglycerol, three unknown aminophospholipids and two unknown phospholipids. The G+C content of the genomic DNA was 68.8 mol%. A novel species Glycomyces halotolerans sp. nov. is proposed, with strain TRM 40137^T (=CCTCC AA 2010013^T = KCTC 19988^T) as the type strain of G. halotolerans.     

<Emphasis Type="Italic">Streptomyces lutosisoli</Emphasis> sp. nov., a novel actinomycete isolated from muddy soil

A novel Gram-stain positive, spore-forming, aerobic actinomycete, designated strain NEAU-QTH3-11^T, was isolated from muddy soil collected from a stream in Qitaihe, Heilongjiang Province, northeast China and characterised using a polyphasic approach. The 16S rRNA gene sequence analysis showed that strain NEAU-QTH3-11^T belongs to the genus Streptomyces and is closely related to Streptomyces rhizosphaerihabitans NBRC 109807^T (99.38%) and Streptomyces mirabilis JCM 4791^T (99.03%). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the strain formed a cluster with S. rhizosphaerihabitans NBRC 109807^T and Streptomyces siamensis NBRC 108799^T (98.62%). The menaquinones were identified as MK-9(H₈), MK-9(H₆) and MK-9(H₄). The phospholipid profile was found to consist of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, an unidentified phospholipid and an unidentified lipid. The major fatty acids were identified as anteiso-C_15:0, iso-C_16:0, C_16:0 and C_15:0. However, multilocus sequence analysis based on five house-keeping genes (atpD, gyrB, rpoB, recA and trpB), low DNA-DNA hybridization results and some phenotypic, physiological and biochemical properties could differentiate the strain from its close relatives in the genus Streptomyces. Therefore, strain NEAU-QTH3-11^T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces lutosisoli sp. nov. is proposed, with NEAU-QTH3-11^T (=DSM 42165^T=CGMCC 4.7198^T) as the type strain.     

<Emphasis Type="Italic">Streptomyces shenzhenensis</Emphasis> sp. nov., a novel actinomycete isolated from mangrove sediment

An actinomycete strain, which was designated 172115^T, was isolated from mangrove soil in Shenzhen, China. Strain 172115^T fell within the genus Streptomyces in the 16S rRNA gene tree and could be grouped into this genus based on its chemotaxonomic and morphological data. The strain shared the highest 16S rRNA gene sequence similarities with Streptomyces lanatus NBRC 12787^T (AB184845) (98.29%) and Streptomyces lucensis NBRC 13056^T (AB184280) (98.26%). The DNA–DNA hybridization values between strain 172115^T and the two most closely related type strains were low enough to justify the assignment of the strain to a novel species. On the basis of these phenotypic, phylogenetic and chemotaxonomic characteristics, 172115^T represents a novel species of the genus Streptomyces, for which, the name Streptomyces shenzhenensis sp. nov. is proposed for strain 172115^T (=CCTCC AA 2011001^T=DSM 42034^T).     

Characterization of <Emphasis Type="Italic">Flavobacterium aquimarinum</Emphasis> sp. nov., a halotolerant bacterium isolated from seawater

A novel, aerobic, Gram-stain-negative, non-motile, non-spore forming, rod-shaped bacterium, designated strain Dol 15-39^T, was isolated from a seawater sample near Geoje Island in the South Sea, Republic of Korea. The strain was found to be oxidase-negative and catalase-positive. The isolate was observed to grow at temperatures from 4 to 37°C, at salinities of up to 7%, and at pH levels from 6 to 9; moreover, it was not able to degrade starch, DNA, esculin, or tyrosine. Phylogenetic analysis based on 16S rRNA gene sequences showed that Dol 15-39^T was most closely related to Flavobacterium jumunjinense HME7102^T with a sequence similarity of 97.3%. However, the levels of DNA-DNA relatedness between Dol 15-39^T and the most closely related species were much lower than 70%, confirming that they represented distinct genomic species. The genomic DNA G + C content of Dol 15-39^T was calculated to be 32.6 mol%. MK-6 was the predominant respiratory quinine, while iso-C_15:0 (25.0%), iso-C_15:1 G (17.0%), and iso-C_17:0 3-OH (10.4%) were the major cellular fatty acids. Phosphatidylethanolamine was identified as a major polar lipid, while various unidentified aminolipids and polar lipids were also detected. Based on polyphasic taxonomic data, Dol 15-39^T represents a novel species of the genus Flavobacterium, for which the name F. aquimarinum sp. nov. is proposed. The type strain is accessible under the culture collection numbers (KEMB 9005-617^T = JCM 31930^T).

Strain JSM 078085^T exhibited a rod-coccus growth cycle and produced a yellow pigment. The strain was able to grow in the presence of 0–12% (w/v) NaCl and at pH 6.0–9.5 and 4–35°C; optimum growth was observed at pH 7.0 and 25–30°C in the absence of NaCl. The peptidoglycan type was A4α (l-Lys–l-Ala–l-Glu). Cell-wall sugars contained galactose and glucose. Strain JSM 078085^T contained menaquinone MK-9(H₂) as the major respiratory quinone and diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol as the major polar lipids. The major cellular fatty acids were anteiso-C_15:0, iso-C_15:0 and anteiso-C_17:0 and the DNA G + C content was 63.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain JSM 078085^T should be assigned to the genus Arthrobacter, being most closely related to the type strain of Arthrobacter rhombi (sequence similarity 97.1%), and the two strains formed a distinct lineage in the phylogenetic tree. The level of DNA–DNA relatedness between strain JSM 078085^T and the type strain of Arthrobacter rhombi was 10.6%. The combination of phylogenetic analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data supported the view that strain JSM 078085^T represents a novel species of the genus Arthrobacter, for which the name Arthrobacter halodurans sp. nov. is proposed. The type strain is JSM 078085^T (=DSM 21081^T=KCTC 19430^T). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain JSM 078085^T is EU583729.

The strain formed well-differentiated aerial and substrate mycelia. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 63101^T belongs to the genus Pseudonocardia, with highest similarity to “Pseudonocardia artemisiae YIM 63587^T” (99.4%). Sequence similarities between strain YIM 63101^T and the other Pseudonocardia species ranged from 97.0 (Pseudonocardia saturnea IMSNU 20052^T) to 94.0% (Pseudonocardia compacta IMSNU 20111^T). The chemotaxonomic characteristics, such as cell wall diaminopimelic acid, whole-cell sugars, fatty acid components and the major menaquinones suggested that the organism belonged to the genus Pseudonocardia.
