A Gram-stain-positive, rod-shaped actinobacterium, designated strain I10A-01402T, was isolated from surface-sterilized roots of a medicinal plant, Perilla frutescens, collected in a suburb of Beijing, China. Chemotaxonomically, the strain contained ll-diaminopimelic acid as the diagnostic diamino acid and MK-8(H4) as the predominant menaquinone. The phospholipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol. The major fatty acids were C17 : 1ω9c, C18 : 1ω9c, C17 : 0, C16 : 0 and iso-C16 : 0. The genomic DNA G+C content was 70.4 mol%. 16S rRNA gene sequence analysis indicated that strain I10A-01402T belonged to the genus Nocardioides . Phylogenetic analyses based on 16S rRNA gene sequences showed that the isolate formed a robust cluster with Nocardioides ginsengisegetis Gsoil 485T, N. koreensis MSL-09T and N. alkalitolerans KSL-1T. On the basis of the evidence from our polyphasic taxonomic study, a novel species, Nocardioides perillae sp. nov., is proposed. The type strain is I10A-01402T ( = CPCC 203382T  = DSM 24552T  = KCTC 29022T).

A novel marine actinomycete, designated strain KJ-029T, was isolated from a marine sediment sample (water depth of 226 m) in Kagoshima, Japan. 16S rRNA gene sequence analysis revealed that the new isolate was most closely related to Micromonospora craniellae LHW 63014T (99.3 % similarity). Phylogenetic analyses of the genus Micromonospora based on 16S rRNA gene sequences showed that strain KJ-029T was clustered with Micromonospora craniellae LHW 63014T and Micromonospora endophytica 202201T. However, digital DNA–DNA hybridization analyses presented low levels of relatedness in the range of 24.8–32.9 % between strain KJ-029T and the above closely related strains. The novel strain contained meso-diaminopimelic acid and 3-OH-diaminopimelic acid, d-glutamic acid, glycine and d-alanine in the cell-wall peptidoglycan. The acyl type of the peptidoglycan was glycolyl and mycolic acids were absent. The major menaquinone was MK-9(H4). The whole-cell sugars consisted of glucose, mannose, xylose and ribose. Phosphatidylethanolamine was detected as the major phospholipid and corresponded to phospholipid type II. The predominant cellular fatty acid was iso-C16 : 0. The DNA G+C content of the genomic DNA was 71.5 mol%. Based on the present polyphasic study, strain KJ-029T represents a novel species of the genus Micromonospora , for which the name Micromonospora pelagivivens sp. nov. is proposed. The type strain is KJ-029T (=NBRC 113519T=TBRC 9233T).

A novel actinobacterium, designated strain NJ2035T, was isolated from soil collected from Abuja, Nigeria and was characterized to determine its taxonomic position. The isolate was found to have chemical and morphological properties associated with members of the genus Lechevalieria . Phylogenetic analyses based on almost-complete 16S rRNA gene sequences indicated that the isolate was closely related to members of the genus Lechevalieria , and was shown to form a distinct phyletic line in the Lechevalieria phylogenetic tree. Strain NJ2035T was most closely related to Lechevalieria roselyniae C81T, Lechevalieria atacamensis C61T and Lechevalieria deserti C68T (98.5 % 16S rRNA gene sequence similarity). Sequence similarities with other members of the genus Lechevalieria were less than 98.2 %. The cell wall of the novel strain contained meso-diaminopimelic acid, and galactose, mannose and rhamnose as the diagnostic sugars. The predominant menaquinone was MK-9(H4). The polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol. DNA–DNA relatedness and phenotypic data showed that the novel isolate and L. roselyniae C81T, L. atacamensis C61T and L. deserti C68T belong to distinct genomic species. On the basis of data from this taxonomic study using a polyphasic approach, strain NJ2035T represents a novel species of the genus Lechevalieria , for which the name Lechevalieria nigeriaca sp. nov. is proposed. The type strain is NJ2035T ( = DSM 45680T = KCTC 29057T = NRRL B-24881T).

A novel actinomycete, designated strain KT2025T, was isolated from arid soil collected from Magusa, northern Cyprus. The taxonomic position of the novel strain was established by using a polyphasic approach. The organism had chemical and morphological features consistent with its classification in the genus Amycolatopsis . Phylogenetic analyses based on 16S rRNA gene sequences supported the classification of the isolate in the genus Amycolatopsis and showed that the organism formed a cluster with Amycolatopsis nigrescens CSC17-Ta-90T, Amycolatopsis minnesotensis 32U-2T, Amycolatopsis sacchari DSM 44468T and Amycolatopsis dongchuanensis YIM 75904T. 16S rRNA gene sequence similarity analysis indicated that strain KT2025T was most closely related to Amycolatopsis lurida DSM 43134T (97.5 %), Amycolatopsis keratiniphila subsp. keratiniphila DSM 44409T (97.4 %), Amycolatopsis keratiniphila subsp. nogabecina DSM 44586T (97.1 %), Amycolatopsis nigrescens DSM 44992T (97.1 %), Amycolatopsis azurea DSM 43854T (97.1 %) and Amycolatopsis minnesotensis DSM 44988T (96.9 %). The organism was found to have chemical features typical of members of the genus Amycolatopsis such as meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, and arabinose and galactose as diagnostic sugars. The predominant menaquinone was MK-9(H4). The polar lipids detected were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and hydroxy-phosphatidylethanolamine. The major fatty acids were iso-C16 : 0, iso-C15 : 0 and iso-C14 : 0. The G+C content of the genomic DNA was 70.8 mol%. Phenotypic data clearly distinguished the isolate from its closest relatives. The combined genotypic and phenotypic data and low levels of DNA–DNA relatedness with its closest relatives indicated that strain KT2025T represents a novel species of the genus Amycolatopsis , for which the name Amycolatopsis magusensis sp. nov. is proposed. The type strain is KT2025T ( = DSM 45510T = KCTC 29056T).

A novel actinobacterium, designated strain NEAU-D13T, was isolated from soil collected from Aohan Banner, Chifeng, Inner Mongolia Autonomous Region, China and characterized using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain NEAU-D13T belonged to the genus Lentzea and shared the highest sequence similarity with Lentzea kentuckyensis JCM 14913 T (99.17 %). Morphological and chemotaxonomic characteristics of the strain also supported its assignment to the genus Lentzea . Cell walls contained meso-diaminopimelic acid as the diagnostic diamino acid and the whole-cell sugars were ribose and mannose. The phospholipid profile contained diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine and phosphatidylinositol. The menaquinone was only MK-9(H4). The major fatty acids were iso-C16:0, C16:0, anteiso-C17:0, iso-C15:0 and anteiso-C15:0. DNA G+C content was 68.71 mol%. Phylogenetic analysis using the 16S rRNA gene sequences showed that the strain formed a stable clade with L. kentuckyensis JCM 14913 T in the genus Lentzea . Meanwhile, a combination of digital DNA–DNA hybridization results and some phenotypic characteristics demonstrated that strain NEAU-D13T could be distinguished from its closely related strain. Therefore, it is concluded that strain NEAU-D13T represents a novel species of the genus Lentzea , for which the name Lentzea alba sp. nov. is proposed, with NEAU-D13T (=CCTCC AA 2019089T=JCM 33970T) as the type strain.

Chakrabartia godavariana PRB40T was compared with Aestuariisphingobium litorale SYSU M10002T to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of C. godavariana PRB40T had high similarity (99.8 %) to that of A. litorale SYSU M10002T. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Chakrabartia . A draft genomic comparison between the two strains revealed an average nucleotide identity of 97.3 % and a digital DNA–DNA hybridization estimate of 79.5±2.9 %, strongly indicating that the two strains represented a single species. In addition, neither strain displayed any striking differences in metabolic, physiological or chemotaxonomic features. Therefore, we propose that Aestuariisphingobium litorale is a later heterotypic synonym of Chakrabartia godavariana .

A Gram-stain-negative, non-motile, rod-shaped bacterial strain, named SJ-16T, was isolated from desert soil collected in Inner Mongolia, northern PR China. Strain SJ-16T grew at pH 6.0–11.0 (optimum, pH 8.0–9.0), 4–40 °C (optimum, 30–35 °C) and in the presence of 0–8 % (w/v) NaCl (optimum, 0–2 %). The strain was negative for catalase and positive for oxidase. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SJ-16T clustered with Luteimonas chenhongjianii 100111T and Luteimonas terrae THG-MD21T, and had 98.8, 98.6, 98.3 and <97.9 % of 16S rRNA gene sequence similarity to strains L. chenhongjianii 100111T, L. terrae THG-MD21T, L. aestuarii B9T and all other type strains of the genus Luteimonas , respectively. The major cellular fatty acids were iso-C15 : 0, iso-C16 : 0, summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) and summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1  ω9c). Diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine were the major polar lipids, and ubiquinone-8 was the only respiratory quinone. The genomic DNA G+C content was 69.3 mol%. The digital DNA–DNA hybridization and average nucleotide identity values of strain SJ-16T to L. chenhongjianii 100111T, L. terrae THG-MD21T, L. rhizosphaerae 4-12T and L. aestuarii B9T were 36.9, 37.5, 24.0 and 21.1 %, and 80.9, 80.6, 80.7 and 76.3 %, respectively. Based on phenotypic, physiological and phylogenetic results, strain SJ-16T represents a novel species of the genus Luteimonas , for which the name Luteimonas deserti is proposed. The type strain is SJ-16T (=CGMCC 1.17694T=KCTC 82207T).

A Gram-staining-positive, aerobic organism, isolated from the Red Sea sponge Spheciospongia vagabunda was investigated to determine its taxonomic position. On the basis of results of 16S rRNA gene sequence analysis strain EG49T was most closely related to Actinokineospora cibodasensis and Actinokineospora baliensis (both 97.3 % similarity) and Actinokineospora diospyrosa and Actinokineospora auranticolor (both 97.0 % similarity). The 16S rRNA gene sequence similarity to all other species of the genus Actinokineospora was <97.0 %. The quinone system of strain EG49T contained the menaquinones MK-9(H4) (47 %), MK-9(H6) (27 %) and MK-9(H2) (15 %) in major amounts. Minor amounts of MK-7(H4) (2 %), MK-9(H0) (1 %), MK-9(H8) (3 %) and MK-10(H4) (3 %) were detected as well in addition to MK-8(H4), MK-8(H6), MK-10(H2) and MK-10(H6) (all <1 %). The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. In the polar lipid profile, diphosphatidylglycerol, phosphatidylethanolamine and hydroxyphosphatidylethanolamine were predominant. Phosphatidylinositol-mannoside, two unidentified phospholipids and two glycoglipids as well as one aminoglycolipid, one aminolipid and one unidentified lipid were found in addition. The fatty acid profile was composed of mainly iso-branched fatty acids: iso-C16 : 0, iso-C14 : 0, iso-C15 : 0 and iso-C16 : 1H. All these findings clearly supported the classification of the strain as representing a member of the genus Actinokineospora . In addition, the results of physiological and biochemical tests also allowed phenotypic differentiation of strain EG49T from the most closely related species of the genus Actinokineospora . Strain EG49T represents a novel species of the genus Actinokineospora , for which we propose the name Actinokineospora spheciospongiae sp. nov., with strain EG49T ( = DSM 45935T = CCM 8480T = LMG 27700T) as the type strain.

To investigate the biodiversity of bacteria in the spring water of the Chengcing Lake Park in Taiwan, a Gram-stain-negative, rod-shaped, non-motile, non-spore-forming and aerobic bacterial strain, designated strain Chen16-4T, was isolated and characterized in a taxonomic study using a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that the closest relatives of strain Chen16-4T were Sphingobium amiense YTT, Sphingobium yanoikuyae GIFU 9882T and Sphingobium scionense WP01T, with sequence similarities of 97.6, 97.1 and 97.0 %, respectively. A phylogenetic tree obtained with 16S rRNA gene sequences indicated that strain Chen16-4T and these three closest relatives formed an independent phylogenetic clade within the genus Sphingobium . The polar lipid pattern, the presence of spermidine and ubiquinone Q-10, the predominance of C18 : 1ω7c in the cellular fatty acid profile and the DNA G+C content also supported affiliation of the isolate to the genus Sphingobium . The DNA–DNA relatedness of strain Chen16-4T with respect to recognized species of the genus Sphingobium was less than 70 %. On the basis of the genotypic, chemotaxonomic and phenotypic data, strain Chen16-4T represents a novel species in the genus Sphingobium , for which the name Sphingobium fontiphilum sp. nov. is proposed. The type strain is Chen16-4T ( = BCRC 80308T = LMG 26342T = KCTC 23559T).
