A Gram-negative, motile, rod-shaped bacteria, designated D7T, was isolated by using the dilution-to-extinction method, from a soil sample taken from Rambla Salada (Murcia, Spain). Growth of strain D7T was observed at 15–40 °C (optimum, 37 °C), pH 5–9 (optimum, 7) and 0–7.5% (w/v) NaCl (optimum, 3%). It is facultatively anaerobic. Phylogenetic analysis based on 16S rRNA gene sequence showed it belongs to the genus Marinobacterium. The in silico DDH and ANI against closest Marinobacterium relatives support its placement as a new species within this genus. The major fatty acids of strain D7T were C16:0, summed feature 3 (C16:1 ω7c/C16:1 ω6c) and summed feature 8 (C18:1 ω7c/C18:1 ω6c). The polar lipid profile consists of phosphatidylethanolamine, phosphatidylglycerol and two uncharacterized lipids. Ubiquinone 8 was the unique isoprenoid quinone detected. The DNA G + C content was 59.2 mol%. On the basis of the phylogenetic, phenotypic, chemotaxonomic and genomic characterization, strain D7T (= CECT 9818T = LMG 31312T) represents a novel species of the genus Marinobacterium for which the name Marinobacterium ramblicola sp. nov. is proposed. Genome-based metabolic reconstructions of strain D7T suggested a heterotrophic and chemolitotrophic lifestyle, as well as the capacity to biosynthetize and catabolize compatible solutes, and to degrade hydrocarbon aromatic compounds.

A novel actinomycete, strain N3-7T, was isolated from a natural cave in Jeju, Republic of Korea, using a dilution method and was subjected to characterization using polyphasic taxonomy. A 16S rRNA gene sequence analysis revealed that the organism belonged to the phylogenetic cluster of the genus Actinocorallia and was most closely related to Actinocorallia glomerata and Actinocorallia longicatena (97.6 and 97.5 % similarity, respectively). The main chemotaxonomic properties of strain N3-7T, such as the principal amino acid of the peptidoglycan, the predominant menaquinone and the polar lipid profile, supported classification in the genus Actinocorallia. The organism was readily differentiated from Actinocorallia species with validly published names on the basis of a broad range of phenotypic properties. Thus the isolate represents a novel species of the genus Actinocorallia, for which the name Actinocorallia cavernae sp. nov. is proposed. The type strain is strain N3-7T (=JCM 13278T=NRRL B-24429T).

A novel halophilic bacterium, designated strain MSS4T, was isolated from the solar salterns of Mesolongi, Greece. The micro-organism, a motile, Gram-stain-positive, aerobic rod, proliferated at salinities of 1.0–4.0 M NaCl, with optimal growth at 2.5 M NaCl. Endospores were not observed. Strain MSS4T showed optimal growth at 37 °C and pH 8.0. The G+C content of its DNA was 47.2 mol%. The polar lipid pattern of strain MSS4T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidic acid and phosphatidylethanolamine. It possessed anteiso-C15 : 0, C18 : 0, C16 : 0 and anteiso-C17 : 0 as the major fatty acids (altogether representing 84.7 % of the total). The predominant isoprenoid quinone was MK-7. The cell-wall peptidoglycan contained meso-diaminopimelic acid. 16S rRNA gene sequence analysis showed that the new isolate has 96.1 % similarity to Bacillus qingdaonensis CM1T and Bacillus aidingensis 17-5T, 95.5 % to Bacillus salarius BH169T and lower similarity to other Bacillus species. These results justify the assignment of strain MSS4T to a novel species within the genus Bacillus, for which the name Bacillus halochares sp. nov. is proposed. The type strain is MSS4T (=LMG 24571T =DSM 21373T).

A novel nitrate-reducing bacterium, CPW406T, was isolated from the sediment of a shallow, freshwater lake. The strain was a Gram-negative, non-motile, non-spore-forming rod, which formed yellow-pigmented colonies on nutrient agar and contained a polyamine pattern with sym-homospermidine as the major compound, MK-6 as the predominant menaquinone, 15 : 0 iso and 17 : 0 iso 3-OH as the major fatty acids and phosphatidylethanolamine and several unknown lipids in the polar lipid profile. The 16S rRNA gene sequence of strain CPW406T was found to be most similar to that of the type strain of Chryseobacterium defluvii (DSM 14219T; 97·9 % similarity). However, DNA–DNA relatedness data and its phenotypic properties showed that strain CPW406T could be distinguished from all known Chryseobacterium species and thus represented a novel species, for which the name Chryseobacterium daecheongense sp. nov. is proposed; the type strain is CPW406T (=DSM 15235T=KCTC 12088T).

A Gram-stain-positive, rod-shaped, endospore-forming bacterium (designated strain CC-Bw-5T) was isolated from chopped tomato stems. The isolate grew at 20–40 °C, pH 6.0–8.0 and tolerated 6  % (w/v) NaCl. The most closely related strains in terms of 16S rRNA gene sequence similarity were Bacillus isabeliae (95.3  %) and Bacillus oleronius (95.3  %). The G+C content of the genomic DNA was 37.2 ± 3.6 mol%. Strain CC-Bw-5T was determined to possess C16 : 0, iso-C14 : 0, iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0 as predominant fatty acids. The polar lipid profile consisted of predominant amounts of diphosphatidylglycerol, and moderate-to-trace amounts of phosphatidylethanolamine, phosphatidylglycerol, two unidentified glycolipids, an unidentified phospholipid and an unidentified phosphoglycolipid. The cell-wall peptidoglycan contained meso-diaminopimelic acid; menaquinone (MK-7) was the predominant respiratory quinone. According to distinct phylogenetic, phenotypic and chemotaxonomic features, strain CC-Bw-5T is proposed to represent a novel species within the genus Bacillus for which the name Bacillus lycopersici sp. nov. is proposed. The type strain is CC-Bw-5T ( = BCRC 80623T = JCM 19140T).

An actinobacterium, strain YIM 70010T, which was isolated from a desert soil sample collected in Egypt, was subjected to a polyphasic taxonomy study. The organism was alkalitolerant and its optimum growth occurred at pH 8·0–9·0. The isolate contained chemotaxonomic markers that were characteristic of the genus Citricoccus, i.e. the peptidoglycan type Lys–Gly–Glu (variation A4α), the predominant menaquinone MK-9(H2) and a polar lipid profile consisting of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two unknown glycolipids. The major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. The G+C content of the genomic DNA was 63·8 mol%. Strain YIM 70010T exhibited a 16S rRNA gene sequence similarity of 99·6 % and DNA–DNA relatedness value of 56 % with Citricoccus muralis DSM 14442T. The phenotypic characteristics and DNA–DNA relatedness data indicate that strain YIM 70010T can be distinguished from C. muralis (DSM 14442T). Therefore, on the basis of the polyphasic taxonomic data presented, a novel species of the genus Citricoccus, Citricoccus alkalitolerans sp. nov. (type strain, YIM 70010T=CCTCC AA 203008T=DSM 15665T=KCTC 19012T) is proposed.

AbstractStrain M2T was isolated from the beach of Cuxhaven, Wadden Sea, Germany, in course of a program to attain new producers of bioactive natural products. Strain M2T produces litoralimycin and sulfomycin-type thiopeptides. Bioinformatic analysis revealed a potential biosynthetic gene cluster encoding for the M2T thiopeptides. The strain is Gram-stain-positive, rod shaped, non-motile, spore forming, showing a yellow colony color and forms extensively branched substrate mycelium and aerial hyphae. Inferred from the 16S rRNA gene phylogeny strain M2T affiliates with the genus Streptomonospora. It shows 96.6% 16S rRNA gene sequence similarity to the type species Streptomonospora salina DSM 44593 T and forms a distinct branch with Streptomonospora sediminis DSM 45723 T with 97.0% 16S rRNA gene sequence similarity. Genome-based phylogenetic analysis revealed that M2T is closely related to Streptomonospora alba YIM 90003 T with a digital DNA-DNA hybridisation (dDDH) value of 26.6%. The predominant menaquinones of M2T are MK-10(H6), MK-10(H8), and MK-11(H6) (> 10%). Major cellular fatty acids are iso-C16:0, anteiso C17:0 and C18:0 10-methyl. The polar lipid profile consisted of diphosphatidylglycerol phosphatidyl glycerol, phosphatidylinositol, phosphatidylcholine, phosphatidylethanolamine, three glycolipids, two unknown phospholipids, and two unknown lipids. The genome size of type strain M2T is 5,878,427 bp with 72.1 mol % G + C content. Based on the results obtained from phylogenetic and chemotaxonomic studies, strain M2T (= DSM 106425 T = NCCB 100650 T) is considered to represent a novel species within the genus Streptomonospora for which the name Streptomonospora litoralis sp. nov. is proposed.

An actinomycete that developed sporangia containing four spores in a single row at the ends of short sporangiophores on branched aerial hyphae was isolated from subtropical forest soil. The isolate contained menaquinone MK-9(H4), glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and madurose in the whole-cell hydrolysate. The 16S rRNA gene sequence indicated that the isolate formed a monophyletic cluster with Planotetraspora mira. On the basis of morphological and chemotaxonomic characteristics, phylogenetic analysis and DNA–DNA relatedness data, a novel species of the genus Planotetraspora is proposed, Planotetraspora silvatica sp. nov. (type strain, TT 00-51T=NBRC 100141T=DSM 44746T).

A Gram-stain-positive, endospore-forming, rod-shaped bacterium, designated XJ259T, was isolated from a cold spring sample from Xinjiang Uyghur Autonomous Region, China. The isolate grew optimally at 20–30 °C and pH 7.3–7.8. Comparative analysis of the 16S rRNA gene sequence showed that isolate XJ259T belonged phylogenetically to the genus Paenibacillus, and was most closely related to Paenibacillus xinjiangensis B538T (with 96.6 % sequence similarity), Paenibacillus glycanilyticus DS-1T (96.3 %) and Paenibacillus castaneae Ch-32T (96.1 %), sharing less than 96.0 % sequence similarity with all other members of the genus Paenibacillus. Chemotaxonomic analysis revealing menaquinone-7 (MK-7) as the major isoprenoid quinone, diphosphatidylglycerol, phosphatidylethanolamine and two unknown phosphoglycolipids as the major cellular polar lipids, a DNA G+C content of 47.0 mol%, and anteiso-C15 : 0 and C16 : 0 as the major fatty acids supported affiliation of the new isolate to the genus Paenibacillus. Based on these data, isolate XJ259T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus algorifonticola sp. nov. is proposed. The type strain is XJ259T ( = CGMCC 1.10223T  = JCM 16598T).
