Abstract A catalase and oxidase-positive strain BA0156T was isolated from a cyanobacterial mat collected from the farmland mud cultivated with sugarcane from Ahmednagar, India. The 16S rRNA gene of strain BA0156T showed the highest percent sequence similarity with Hydrogenophaga borbori LMG 30805T (98.55 %), followed by H. flava DSM 619T (98.35 %) and H. intermedia DSM 5680T (98.21 %). The strain BA0156T consisted of major fatty acids, C16:0 (25.1 %) and C17:0 cyclo (3.9 %), whereas phosphatidylethanolamine and diphosphatidylglycerol were the major polar lipids. The OrthoANI and dDDH values between strain BA0156T and its closest relative H. borbori LMG 30805T were 84.59 % and 28.3 %, respectively. The DNA G+C content of strain BA0156T was 69.42 mol %. Furthermore, the biochemical and physiological features of strain BA0156T showed a distinct pattern from their closest phylogenetic neighbours. The phenotypic, genotypic and chemotaxonomic characteristics indicated that the strain BA0156T represents a new species for which the name Hydrogenophaga crocea (type strain BA0156 T = MCC 3062T = KCTC 72452T = JCM 34507T) is proposed.

Three novel endophytic strains, designated 17B10-2-12T, 26C10-4-4 and D13-10-4-9, were isolated from the bark of Populus euramericana in Heze, Shandong Province, China. They were Gram-reaction-negative, aerobic, non-motile, short-rod-shaped, oxidase-positive and catalase-negative. A phylogenetic analysis of the 16S rRNA gene showed that the three novel strains clustered with members of the family Comamonadaceae and formed a distinct branch. The isolates shared 100 % similarities among themselves and had the highest sequence similarity with Xenophilus azovorans DSM 13620T (95.2 %) and Xenophilus arseniciresistens YW8T (95.0 %), and less than 95.0 % sequence similarities with members of other species. Their major fatty acids were C16 : 0, C17 : 0 cyclo, C18 : 1ω7c and C16 : 1ω7c/C16 : 1ω6c. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and three unknown aminophospholipids. The predominant quinone was ubiquinone-8 (Q-8). The DNA G+C content was 69.5–70.0 mol%. Based on data from a polyphasic taxonomy study, the three strains represent a novel species of a novel genus of the family Comamonadaceae, for which the name Corticibacter populi gen. nov., sp. nov. is proposed. The type strain is 17B10-2-12T ( = CFCC 12099T = KCTC 42091T).

Three novel Gram-positive, aerobic, chemoheterotrophic, motile, non-endospore-forming, orange-pigmented bacteria designated strains T13T, T90T and R8T were isolated from the Tabernas Desert biocrust (Almería, Spain). Cells of the three strains were coccus-shaped and occurred singly, in pairs or clusters. The three strains were oxidase-negative and catalase-positive, and showed a mesophilic, neutrophilic and non-halophilic metabolism. Based on the 16S rRNA gene sequences, the closest neighbours of strains T13T, T90T and R8T were Kineococcus aurantiacus IFO 15268T, Kineococcus gypseus YIM 121300T and Kineococcus radiotolerans SRS 30216T (98.5%, 97.1% and 97.9% gene sequence similarity, respectively). The genomes were sequenced, and have been deposited in the GenBank/EMBL/DDBJ databases under the accession numbers JAAALL000000000, JAAALM000000000 and JAAALN000000000, respectively, for strains T13T, T90T and R8T. The average nucleotide identity (ANIb) and digital DNA-DNA hybridization (dDDH) values confirmed their adscription to three new species within the genus Kineococcus. The genomic G + C content of strains T13T, T90T and R8T ranged from 75.1% to 76.3%. The predominant fatty acid of all three strains was anteiso-C15:0. According to a polyphasic study, strains T13T, T90T and R8T are representatives of three new species in the genus Kineococcus, for which names Kineococcus vitellinus sp. nov. (type strain T13T = CECT 9936T = DSM 110024T), Kineococcus indalonis sp. nov. (type strain T90T = CECT 9938T = DSM 110026T) and Kineococcus siccus sp. nov. (type strain R8T = CECT 9937T = DSM 110025T) are proposed.

AbstractStrain SN6T is a non-motile and non-spore-forming gram-negative bacterium which was isolated from the stool sample of an Amazonian patient. The optimum growth was observed at 37 °C, pH 7, and 0–5 g/l of NaCl. Based on the 16S rRNA gene sequence similarity, the strain SN6T exhibited 97.5% identity with Vitreoscilla stercoraria strain ATCC_15218 (L06174), the phylogenetically closest species with standing in nomenclature. The predominant fatty acid was hexadecenoic acid (31%). The genomic DNA G + C content of the strain SN6T was 49.4 mol %. After analysis of taxonogenomic data, phenotypic and biochemical characteristics, we concluded that strain SN6T represents a new species of the genus Vitreoscilla for which the name Vitreoscilla massiliensis sp.nov is proposed. The type strain is SN6T (=CSUR P2036 = LN870312 = DSM 100958).

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).

Abstract A Gram-stain-negative, gliding-motile, positive for catalase, facultative anaerobic, designated strain XSD401T, was isolated from the red algae of Xiaoshi Island, Shandong Province, China. Growth occurred at 20–37 °C (optimum, 33 °C), pH 5.5–9.5 (optimum, pH 6.5–7.5), and with 0.5–5% (w/v) NaCl (optimum, 3%). The main fatty acids are iso-C15:0, iso-C15:1 G, iso-C17:0 3-OH, iso-C15:0 3-OH, C16:0. Phosphatidylethanolamine (PE), three unidentified aminolipids (AL1, AL2, AL3) and one unidentified lipid (L) were the major polar lipids. The G+C content of the genomic DNA was 33.9 mol%. Strain XSD401T had the highest sequence similarity (96.88%) to the 16S rRNA gene of Psychroserpens damuponensis KCTC 23539T. The similarities with Psychroserpens burtonensis DSM 12212T was 96.31%. The dDDH values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T, were 20.40% and 20.30%, respectively. The average nucleotide identity (ANI) values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T were 76.91%, 76.88%, respectively. The differences in morphology, physiology and genotype from the previously described taxa support the classification of strain XSD401T as a representative of a novel species of the genus Psychroserpens, for which the name Psychroserpens luteus sp. nov. is proposed. The type strain is XSD401T (= MCCC 1H00396T = KCTC 72684T = JCM 33931T).

We describe a new species of Phrynobatrachus from the eastern part of the Upper Guinea forest region, Ghana, West Africa. Morphologically, the new species can be distinguished from all of its congeners by the combination of a slender body, short and pointed snout, a relatively warty dorsum, a black-spotted throat in both sexes, a gular flap in males, a dark spotted chest, a white-greyish venter with occasional blackish spots, rudimentary pedal webbing, none to slightly dilated finger tips and strongly delated toe tips, presence of both inner and outer metatarsal tubercles and absence of a dark face mask, eyelid tubercles and longer dorsal ridges. We collected mitochondrial DNA (mtDNA) sequence data from the 16S rRNA gene to measure the genetic diversity of the new species, and to estimate phylogenetic relationships. The new species is a distinct and monophyletic evolutionary lineage most closely related to Phrynobatrachus gutturosus, P. fraterculus and P. maculiventris. The discovery of this new species highlights that the biodiversity of West African forests is still incompletely known and that the few remaining forests need urgent protection.

Two novel thermophilic micro-organisms, designated YMO81T and YMO722T, were isolated from a high-temperature compost (internal temperature >95 °C). The isolates were able to grow at 80 °C in a nutrient broth and in a synthetic medium. Cells were aerobic, Gram-negative rods (0.3×4.0 μm). Spore formation was not observed. Strain YMO81T grew at 83 °C and pH 6.9–8.9 and grew optimally at 78 °C and pH 7.5 with 2 % NaCl. For growth in a synthetic minimal medium at 70 °C, the vitamins biotin, folic acid and thiamine and the amino acids glutamine and methionine were essential for growth of both strains; at 80 °C, strain YMO81T also required histidine, isoleucine, leucine, lysine, phenylalanine, serine, tryptophan and valine. Cellular fatty acids of the isolates comprised mainly iso-C17 : 0 and anteiso-C17 : 0. The DNA G+C contents of strains YMO81T and YMO722T were 70 and 64 mol%, respectively. When the 16S rRNA gene sequences of the isolates were compared with those of other bacteria, highest similarity was observed with Planifilum yunnanense LA5T (90 % 16S rRNA gene sequence similarity). DNA–DNA relatedness between strain YMO722T and strain YMO81T was 55 %. N 4-Aminopropylspermine was identified as a major polyamine, which suggested that the isolates were distinct from other related taxa. On the basis of phylogenetic, phenotypic and chemotaxonomic analyses, we propose a new genus, Calditerricola gen. nov., and two novel species, the type species Calditerricola satsumensis sp. nov., with type strain YMO81T (=ATCC BAA-1462T =JCM 14719T =DSM 45223T), and Calditerricola yamamurae sp. nov., with type strain YMO722T (=ATCC BAA-1461T =JCM 14720T =DSM 45224T).

In this article, a new species of salamander of the genus Bolitoglossa (Eladinea) from the cloud forest near La Mucuy in Sierra Nevada de Mérida, Venezuelan Andes, is described. Bolitoglossa mucuyensis sp. nov. differs from all Venezuelan salamanders, except B. orestes, by a larger SVL/TL ratio, and from La Culata salamander B. orestes by a reduced webbing extension of the front and hind limbs. Additionally, B. mucuyensis sp. nov. and B. orestes diverge 3.12% in terms of the nucleotide sequence of the 16S rRNA gene, as previously reported, and in 8.1% for the cytb gene as shown in this study.
