A facultatively anaerobic, non-spore-forming, non-motile, catalase- and oxidase-positive, Gram-reaction-negative, coccoid to short rod-shaped strain, designated FLN-7T, was isolated from activated sludge of a wastewater biotreatment facility. The strain was able to hydrolyse amide pesticides (e.g. diflubenzuron, propanil, chlorpropham and dimethoate) through amide bond cleavage. Strain FLN-7T grew at 4–42 °C (optimum 28 °C), at pH 5.0–8.0 (optimum pH 7.0) and with 0–5.0 % (w/v) NaCl (optimum 1.0 %). The major respiratory quinone was ubiquinone-10. The major cellular fatty acid was C18 : 1ω7c. The genomic DNA G+C content of strain FLN-7T was 66.4±0.5 mol%. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine and an unidentified glycolipid. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain FLN-7T was a member of the genus Paracoccus and showed highest 16S rRNA gene sequence similarities with Paracoccus aminovorans JCM 7685T (99.2 %), P. denitrificans DSM 413T (97.8 %), P. yeei CDC G1212T (97.3 %) and P. thiocyanatus THI 011T (97.1 %). Strain FLN-7T showed low DNA–DNA relatedness with P. aminovorans KACC 12261T (36.5±3.4 %), P. denitrificans KACC 12251T (30.5±2.6 %), P. yeei CCUG 46822T (26.2±2.4 %) and P. thiocyanatus KACC 13901T (15.5±0.9 %). Based on the phylogenetic analysis, DNA–DNA hybridization, whole-cell fatty acid composition and biochemical characteristics, strain FLN-7T was clearly distinguished from all recognized species of the genus Paracoccus and should be classified in a novel species, for which the name Paracoccus huijuniae sp. nov. is proposed. The type strain is FLN-7T ( = KACC 16242T  = ACCC 05690T).

Strain M-07T was isolated from nitrifying–denitrifying activated sludge treating piggery wastewater. Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that strain M-07T belonged to the genus Advenella . 16S rRNA gene sequence similarity between M-07T and Advenella incenata CCUG 45225T, Advenella mimigardefordensis DPN7T and Advenella kashmirensis WT001T was 96.5, 97.3 and 96.9 %, respectively. The DNA G+C content of strain M-07T was 49.5 mol%, which was approximately 5 mol% lower than the range for the genus Advenella (53.5–58.0 mol%). The predominant cellular fatty acids of strain M-07T were C16 : 0, summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), C17 : 0 cyclo and summed feature 2 (comprising one or more of C14 : 0 3-OH, iso-C16 : 1 I, an unidentified fatty acid with an equivalent chain-length of 10.928 and C12 : 0 alde). The isoprenoid quinone was Q-8. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness, strain M-07T should be classified as a novel species of the genus Advenella , for which the name Advenella faeciporci sp. nov. is proposed. The type strain is M-07T ( = JCM 17746T  = KCTC 23732T).

Strain SPC-1T was isolated from the phyllosphere of Cynara cardunculus L. var. sylvestris (Lamk) Fiori (wild cardoon), a Mediterranean native plant considered to be the wild ancestor of the globe artichoke and cultivated cardoon. This Gram-stain-negative, catalase-positive, oxidase-negative, non-spore-forming, rod-shaped and non-motile strain secreted copious amounts of an exopolysaccharide, formed slimy, viscous, orange-pigmented colonies and grew optimally at around pH 6.0–6.5 and 26–30 °C in the presence of 0–0.5 % NaCl. Phylogenetic analysis based on comparisons of 16S rRNA gene sequences demonstrated that SPC-1T clustered together with species of the genus Sphingomonas sensu stricto. The G+C content of the DNA (66.1 mol%), the presence of Q-10 as the predominant ubiquinone, sym-homospermidine as the predominant polyamine, 2-hydroxymyristic acid (C14 : 0 2-OH) as the major hydroxylated fatty acid, the absence of 3-hydroxy fatty acids and the presence of sphingoglycolipid supported this taxonomic position. 16S rRNA gene sequence analysis showed that SPC-1T was most closely related to Sphingomonas hankookensis ODN7T, Sphingomonas insulae DS-28T and Sphingomonas panni C52T (98.19, 97.91 and 97.11 % sequence similarities, respectively). However, DNA–DNA hybridization analysis did not reveal any relatedness at the species level. Further differences were apparent in biochemical traits, and fatty acid, quinone and polyamine profiles leading us to conclude that strain SPC-1T represents a novel species of the genus Sphingomonas , for which the name Sphingomonas cynarae sp. nov. is proposed; the type strain is SPC-1T ( = JCM 17498T = ITEM 13494T). A component analysis of the exopolysaccharide suggested that it represents a novel type of sphingan containing glucose, rhamnose, mannose and galactose, while glucuronic acid, which is commonly found in sphingans, was not detected.

Three strains of an anaerobic, Gram-stain-positive coccobacillus were isolated from the intestines of mice. These strains shared 100 % similarity in their 16S rRNA gene sequences, but were distantly related to any described members of the family Lachnospiraceae (<94 %). The most closely related species with names that have standing in nomenclature were Robinsoniella peoriensis , Ruminococcus gnavus , Blautia producta and Clostridium xylanolyticum . Phylogenetic relationships based on 16S rRNA gene sequence analysis were confirmed by partial sequencing of hsp60 genes. The use of an in-house database search pipeline revealed that the new isolates are most prevalent in bovine gut samples when compared with human and mouse samples for Ruminococcus gnavus and B. producta . All three isolated strains shared similar cellular fatty acid patterns dominated by C16 : 0 methyl ester. Differences in the proportions of C12 : 0 methyl ester, C14 : 0 methyl ester and C18 : 1 cis-11 dimethyl acetal were observed when compared with phylogenetically neighbouring species. The major short-chain fatty acid produced by strain SRB-530-5-HT was acetic acid. This strain tested positive for utilization of d-fructose, d-galacturonic acid, d-malic acid, l-alanyl l-threonine and l-glutamic acid but was negative for utilization of amygdalin, arbutin, α-d-glucose, 3-methyl d-glucose and salicin, in contrast to the type strain of the closest related species Robinsoniella peoriensis . The isolates were not able to use mannitol for growth. Based on genotypic, phenotypic and chemotaxonomic characteristics, we propose to create the new genus and species Murimonas intestini gen. nov., sp. nov. to accommodate the three strains SRB-530-5-HT ( = DSM 26524T = CCUG 63391T) (the type strain of Murimonas intestini), SRB-509-4-S-H ( = DSM 27577 = CCUG 64595) and SRB-524-4-S-H ( = DSM 27578 = CCUG 64594).

A previously undescribed, slowly growing, non-chromogenic Mycobacterium strain (299T) was isolated from the sputum sample of a patient with a symptomatic pulmonary infection. Phenotypically, strain 299T was generally similar to Mycobacterium koreense DSM 45576T and Mycobacterium triviale ATCC 23292T. The 16S rRNA gene sequence of strain 299T was similar to that of M. koreense DSM 45576T (GenBank accession no. AY734996, 99.5 % similarity); however, it differed substantially from that of M. triviale ATCC 23292T (X88924, 98.2 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 299T clustered together with M. koreense DSM 45576T and M. triviale ATCC 23292T, supported by high bootstrapping values (99 %). Unique mycolic acid profiles and phylogenetic analysis based on two different chronometer molecules, the hsp65 and rpoB genes, strongly supported the taxonomic status of this strain as representing a distinct species. These data support the conclusion that strain 299T represents a novel mycobacterial species, for which the name Mycobacterium parakoreense sp. nov. is proposed. The type strain is 299T ( = DSM 45575T = KCTC 19818T).

During a study of endophytic bacteria from coastal dune plants, a bacterial strain, designated YC6881T, was isolated from the root of Rosa rugosa collected from the coastal dune areas of Namhae Island, Korea. The bacterium was found to be Gram-staining-negative, motile, halophilic and heterotrophic with a single polar flagellum. Strain YC6881T grew at temperatures of 4–37 °C (optimum, 28–32 °C), at pH 6.0–9.0 (optimum, pH 7.0–8.0), and at NaCl concentrations in the range of 0–7.5 % (w/v) (optimum, 4–5 % NaCl). Strain YC6881T was catalase- and oxidase-positive and negative for nitrate reduction. According to phylogenetic analysis using 16S rRNA gene sequences, strain YC6881T belonged to the genus Rhizobium and showed the highest 16S rRNA gene sequence similarity of 96.9 % to Rhizobium rosettiformans , followed by Rhizobium borbori (96.3 %), Rhizobium radiobacter (96.1 %), Rhizobium daejeonense (95.9 %), Rhizobium larrymoorei (95.6 %) and Rhizobium giardinii (95.4 %). Phylogenetic analysis of strain YC6881T by recA, atpD, glnII and 16S–23S intergenic spacer (IGS) sequences all confirmed the phylogenetic arrangements obtained by using 16S rRNA gene sequences. Cross-nodulation tests showed that strain YC6881T was a symbiotic bacterium that nodulated Vigna unguiculata and Pisum sativum. The major components of the cellular fatty acids were C18 : 1ω7c (53.7 %), C19 : 0 cyclo ω8c (12.6 %) and C12 : 0 (8.1 %). The DNA G+C content was 52.8 mol%. Phenotypic and physiological tests with respect to carbon source utilization, antibiotic resistance, growth conditions, phylogenetic analyses of housekeeping genes recA, atpD and glnII, and fatty acid composition could be used to discriminate strain YC6881T from other species of the genus Rhizobium in the same sublineage. Based on the results obtained in this study, strain YC6881T is considered to represent a novel species of the genus Rhizobium , for which the name Rhizobium halophytocola sp. nov. is proposed. The type strain is YC6881T ( = KACC 13775T = DSM 21600T).

Two morphologically similar halophilic strains, named USBA 874 and USBA 960T, were isolated from water and sediment samples collected from the Zipaquirá salt mine in the Colombian Andes. Both isolates had non-spore-forming, Gram-stain-negative and motile cells that grew aerobically. The strains grew optimally at 30 °C, pH 7.0 and with 25 % NaCl (w/v). The isolates showed almost identical 16S rRNA gene sequences (99.0 % similarity). The predominant quinones of USBA-960T were Q-8, Q-7 and Q-9. The major cellular fatty acids were C19 : 0 cyclo ω8c, C18 : 0 and C16 : 0. According to 16S rRNA gene sequencing, the closest phylogenetic relatives are Salinisphaera species (similarity between 93.6 and 92.3 %), Abyssibacter profundi OUC007T (88.6 %) and Oceanococcus atlanticus 22II-S10r2T (88.7 %). In addition, the result of genome blast distance phylogeny analysis between strains USBA 874 and USBA 960T, Salinisphaera halophila (YIM 95161T), Salinisphaera shabanensis (E1L3AT), Salinisphaera orenii (MK-B5T) and Salinisphaera japonica (YTM-1T) was 18.5 %. Other in silico species delineation analyses also showed low identity such as ANIb and ANIm values (<69.0 and <84.0 % respectively), TETRA (<0.81) and AAI values (<0.67). Genome sequencing of USBA 960T revealed a genome size of 2.47 Mbp and a G+C content of 59.71 mol%. Phylogenetic analysis of strains USBA 874 and USBA 960T indicated that they formed a different lineage within the family Salinisphaeraceae . Based on phenotypic and chemotaxonomic characteristics, phylogenetic analysis and DNA–DNA relatedness values, along with identity at whole genome level, it can be concluded that strains USBA 960T and USBA 874 represent a novel genus of the family Salinisphaeraceae and the name Salifodinibacter halophilus gen. nov., sp. nov. is proposed. The type strain is USBA 960T (CMPUJ U095T=CECT 30006T).

A Gram-stain-negative, strictly aerobic, non-motile and rod-shaped bacterial strain, MYP1-1T, was isolated from the intestine of a stalked sea squirt (Styela clava) of the South Sea in the Republic of Korea. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain MYP1-1T clustered with the type strains of Halocynthiibacter species and Pseudohalocynthiibacter aestuariivivens . Strain MYP1-1T exhibited 16S rRNA gene sequence similarity values of 97.0–97.6 % to the type strains of Halocynthiibacter namhaensis , Halocynthiibacter arcticus and P. aestuariivivens . The phylogenetic tree based on genomic sequences showed that strain MYP1-1T formed a distinct branch separating it from the type strains of two Halocynthiibacter species and P. aestuariivivens and other taxa. The DNA G+C content of strain MYP1-1T from its genomic sequence was 55.0 mol%. Strain MYP1-1T contained Q-10 as the predominant ubiquinone and C18 : 1  ω7c as the major fatty acid. The major polar lipids of strain MYP1-1T were phosphatidylcholine, phosphatidylglycerol, one unidentified lipid and one unidentified aminolipid. The differences in fatty acid and polar lipid profiles and other differential phenotypic properties made it reasonable to distinguish strain MYP1-1T from the genera Halocynthiibacter and Pseudohalocynthiibacter . On the basis of the polyphasic taxonomic investigations, we conclude that strain MYP1-1T constitutes a new genus and species within the class Alphaproteobacteria , for which the name Paenihalocynthiibacter styelae gen. nov., sp. nov. is proposed. The type strain is MYP1-1T (=KCTC 82143T=NBRC 114355T).

A Gram-negative, non-spore-forming, non-flagellated, motile-by-gliding rod, designated SSK2-3T, was isolated from the junction between seawater and a freshwater spring at Jeju island, South Korea. Strain SSK2-3T grew optimally at 25–30 °C, at pH 7.0–7.5 and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SSK2-3T clustered with type strains of species of the genus Mariniflexile , with which it exhibited 97.2–97.8 % 16S rRNA gene sequence similarity. Sequence similarity between the isolate and the other strains used in the phylogenetic analysis was <95.6 %. Strain SSK2-3T contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C15 : 1 G and C15 : 0 as the major fatty acids. The major polar lipids of strain SSK2-3T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain SSK2-3T was 32.4 mol%. DNA–DNA relatedness between the isolate and Mariniflexile gromovii KCTC 12570T, Mariniflexile fucanivorans DSM 18792T and Mariniflexile aquimaris HWR-17T was 19, 15 and 20 %, respectively. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain SSK2-3T is separate from other members of the genus Mariniflexile . On the basis of the data presented, strain SSK2-3T is considered to represent a novel species of the genus Mariniflexile , for which the name Mariniflexile jejuense sp. nov. is proposed. The type strain is SSK2-3T ( = KCTC 23958T  = CCUG 62414T). An emended description of the genus Mariniflexile is given.

The 16S Rrna Gene

A phytoplasma was identified in naturally infected wild Balanites triflora plants exhibiting typical witches’ broom symptoms (Balanites witches’ broom: BltWB) in Myanmar. The 16S rRNA gene sequence revealed that BltWB phytoplasma had the highest similarity to that of ‘Candidatus Phytoplasma ziziphi’ and it was also closely related to that of ‘Candidatus Phytoplasma ulmi ’. Phylogenetic analysis of the 16S rRNA gene sequences indicated that the BltWB phytoplasma clustered as a discrete subclade with Elm yellows phytoplasmas. RFLP analysis of the 16S rRNA gene including the 16S–23S spacer region differentiated the BltWB phytoplasma from ‘Ca. P. ziziphi ’, ‘Ca. P. ulmi ’ and ‘Candidatus Phytoplasma trifolii ’. Analysis of additional ribosomal protein (rp) and translocase protein (secY) gene sequences and phylogenetic analysis of BltWB showed that this phytoplasma was clearly distinguished from those of other ‘Candidatus Phytoplasma ’ taxa. Taking into consideration the unique plant host and the restricted geographical occurrence in addition to the 16S rRNA gene sequence similarity, the BltWB phytoplasma is proposed to represent a novel taxon, ‘Candidatus Phytoplasma balanitae’.

A novel actinomycete, strain 30EHST, was isolated from the rhizospheric soil under an elephant ear plant (Caladium bicolor) in Jomthong district, Bangkok, Thailand. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 30EHST fell within the cluster of the genus Streptosporangium . Chemical composition analysis confirmed that the strain represented a member of the genus Streptosporangium even though this strain produced a tightly packed single spore on aerial hyphae. Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that strain 30EHST was most closely related to Streptosporangium fragile NBRC 14311T (98.1 %), Streptosporangium carneum NBRC 15562T (97.8 %) and Streptosporangium violaceochromogenes NBRC 15560T (97.4 %). The DNA–DNA hybridization relatedness values between strain 30EHST and the above three strains were below 70 %. Based on combined data for phylogenetic analysis, DNA–DNA hybridization relatedness and physiological characteristics, it was concluded that strain 30EHST should be classified as representing a novel species of the genus Streptosporangium . We propose the name Streptosporangium jomthongense sp. nov., with the type strain 30EHST ( = BCC 53154T = NBRC 110047T). An emended description of the genus Streptosporangium is also proposed.
