[Ti] Título: Draft genome and description of Consotaella salsifontis gen. nov. sp. nov., a halophilic, free-living, nitrogen-fixing alphaproteobacterium isolated from an ancient terrestrial saline spring. [So] Source: Int J Syst Evol Microbiol;67(10):3744-3751, 2017 Oct. [Is] ISSN: 1466-5034 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: A free-living, nitrogen-fixing, mesophilic and facultative aerobe, designated strain USBA 369 , was isolated from a terrestrial saline spring of the Colombian Andes. The non-sporulating rods (1.5×0.8 µm) with rounded ends stained Gram-negative and were motile by means of lophotrichous flagella. The strain grew optimally at 30 °C, at pH 6.9-7.5 and with 1.5 % (w/v) NaCl. The major fatty acids detected were C18 : 1ω7c and C19 : 0 cyclo ω8c, and the respiratory lipoquinone ubiquinone 10 (Q-10) was present. The genome consisted of 4.65 Mb with a DNA G+C content of 64.3 mol%. A total of 4371 genes were predicted and, of those, 4300 were protein coding genes and 71 were RNA genes. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain USBA 369 formed a different lineage within the class Alphaproteobacteria, order Rhizobiales, and DNA homology studies with the most closely related genera, Aurantimonas, Aureimonas and Rhizobium (95 % 16S rRNA gene sequence similarity), showed values of <15 %. The phylogenomic analysis provided evidence for clear phylogenetic divergence between strain USBA 369 and the closely related genera. On the basis of the phenotypic, chemotaxonomic and phylogenomic evidence, strain USBA 369 is considered to represent a novel genus and a novel species for which the name Consotaella salsifontis gen. nov., sp. nov. is proposed. The type strain is USBA 369 (=KCTC 22549 =CMPUJ U369 ).

[Ti] Título: Desulfuribacillus stibiiarsenatis sp. nov., an obligately anaerobic, dissimilatory antimonate- and arsenate-reducing bacterium isolated from anoxic sediments, and emended description of the genus Desulfuribacillus. [So] Source: Int J Syst Evol Microbiol;67(4):1011-1017, 2017 Apr. [Is] ISSN: 1466-5034 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: A novel anaerobic, Gram-stain-negative, endospore-forming bacterium, designated strain MLFW-2T, was isolated from anoxic sediments collected from the drainage area of a geothermal spring near Mono Lake, CA, USA. Optimal growth was achieved at 34 °C and pH 8.25-8.50 in medium containing 0.75 % (w/v) NaCl. Catalase, but not oxidase, was produced. Strain MLFW-2T was an obligate anaerobe capable of respiring with nitrate, nitrite, DMSO, arsenate, antimonate, selenate and selenite as terminal electron acceptors. Lactate, pyruvate, formate and H2 could serve as electron donors to support growth. The isolate was incapable of fermentation. The predominant fatty acids were C16 : 0, C16 : 1ω9c, C16 : 1ω7c, C18 : 1ω9c and C18 : 1ω7c. The major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. The only isoprenoid quinone detected was menaquinone 7 (MK-7). The DNA G+C content was 38.2 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence demonstrated that strain MLFW-2T was a member of the order Bacillales and was most closely related to Desulfuribacillus alkaliarsenatis AHT28T (93.9 % similarity). On the basis of phenotypic and phylogenomic evidence, strain MLFW-2T represents a novel species of the genus Desulfuribacillus, for which the name Desulfuribacillus stibiiarsenatis sp. nov. is proposed. The type strain is MLFW-2T (=DSM 28709T=JCM 30866T). An emended description of the genus Desulfuribacillus is also provided.

[Ti] Título: Actinocrinis puniceicyclus gen. nov., sp. nov., an actinobacterium isolated from an acidic spring. [So] Source: Int J Syst Evol Microbiol;67(3):602-609, 2017 Mar. [Is] ISSN: 1466-5034 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: An aerobic, mildly acidophilic actinobacterium was isolated from the Ochre Beds bog in Kootenay National Park, Canada. Cells of isolate OB1T were Gram-stain-positive, non-motile, pink- to purple-pigmented filaments. The pH range for growth was pH 3.5-6.5 (optimum pH 5.5), and the temperature range was 13-30°C. The major cellular fatty acids were i-C16 : 0 (28.5 %), i-C15 : 0 (14.6 %) and ai-C15 : 0 (14.3 %), and the major polar lipid was phosphohexose. The major quinone was menaquinone-11 (MK-11), and the peptidoglycan type was A1γ. The DNA G+C content was 70.2 %. Along with growth on complex media including yeast extract, proteose peptone, casamino acids and tryptic soy broth, growth occured on mono- and disaccharides (glucose, sucrose, galactose and xylose) and polysaccharides (starch, gellan, pectin, xylan and alginate). Anaerobic growth was not observed. The cells did not fix atmospheric nitrogen. On the basis of comparative 16S rRNA gene sequence analysis, this isolate belonged to the family Actinospicaceae, in the suborder Catenulisporineae of the order Actinomycetales. The most closely related species was Actinospica robiniae. However, the 16S rRNA gene sequence identity to this bacterium was low (92.8 %) and there were several chemotaxonomic differences from this species. We therefore propose a novel genus and species, Actinocrinis puniceicyclus gen. nov., sp. nov., with strain OB1T (=DSM 45618T=ATCC BAA-2771T) as the type strain.

[Ti] Título: Soortia roseihalophila gen. nov., sp. nov., a new taxon in the order Balneolales isolated from a travertine spring, and description of Soortiaceae fam. nov. [So] Source: Int J Syst Evol Microbiol;67(1):113-120, 2017 Jan. [Is] ISSN: 1466-5034 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: A novel Gram-stain-negative, slightly halophilic, motile, curved rod with a horseshoe shape, designated strain Bsw-2bT, was isolated from Badab-Soort travertine spring in Iran. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain Bsw-2bT belongs to the order Balneolales, showing 84.6 % sequence similarity to Gracilimonastropica DSM 19535T and 84.4 % and 83.9 % sequence similarity to Gracilimonas rosea CL-KR2T and Balneola vulgaris DSM 17893T, respectively. In addition, phenotypic and physiological features could clearly differentiate strain Bsw-2bT from species of the most closely related genera, Gracilimonas, Balneola, Aliifodinibius and Fodinibius. The strain was able to grow with 1-3 % (w/v) (optimum at 2 %) NaCl, at temperatures of 28-34 °C (optimum at 30 °C) and between pH 6.0 and 8.0 (optimum at pH 7.0). The major cellular fatty acids of strain Bsw-2bT were iso-C15 : 0, iso-C13 : 0 and iso-C14 : 0. The polar lipid profile of strain Bsw-2bT was composed predominantly of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, an unknown glycolipid and four unknown phospholipids. The DNA G+C content was 40.5 mol%. Based on the evidence from the polyphasic study, strain Bsw-2bT represents a novel species in a novel genus within a new family, for which the name Soortia roseihalophila gen. nov., sp. nov. is proposed, within the new family Soortiaceae fam. nov. The type strain is strain Bsw-2bT (=IBRC-M 10915T=LMG 28547T).

[Is] ISSN: 1466-5034 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: A bacterial strain, designated MIB-4T, was isolated from a freshwater spring in Taiwan and characterized using a polyphasic taxonomy approach. Cells of strain MIB-4T were Gram-staining-negative, aerobic, non-motile rods that formed pale pink colonies. Growth occurred at 15-30 °C (optimum, 25 °C), at pH 7-8 (optimum, pH 7) and with 0-0.5 % NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain MIB-4T belonged to the genus Flectobacillus and was most closely related to Flectobacillus lacus CL-GP79T with sequence similarity of 98.7 %. Strain MIB-4T contained C16 : 1ω5c, iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) as the predominant fatty acids. The major isoprenoid quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine, six unidentified aminophospholipids, one unidentified glycolipid, one unidentified phospholipid and three unidentified lipids. The DNA G+C content of the genomic DNA was 37.6 mol%. The DNA-DNA hybridization value for strain MIB-4T with F. lacus CL-GP79T was less than 32 %. On the basis of the phylogenetic inference and phenotypic data, strain MIB-4T should be classified as a representative of a novel species, for which the name Flectobacillus fontis sp. nov. is proposed.

[Is] ISSN: 1848-6312 [Cp] País de publicação: Croatia [La] Idioma: eng [Ab] Resumo: Investigations of natural radioactivity in water, air, and soil are conducted frequently and routinely. Exposure to high concentrations of natural radioactive radon gas can cause irradiation of respiratory organs, which can lead to lung cancer. This paper presents measurements of radon activity concentrations in dug wells and natural springs of the Tuzla area (Bosnia and Herzegovina), which ranged from 214 to 3702 mBq L-1. Our results have shown that the radon activity concentration did not exceed the EU reference level for radon in drinking water (100 Bq L-1).

[Ti] Título: Trichloroethylene (TCE) in tree cores to complement a subsurface investigation on residential property near a former electroplating facility. [So] Source: Environ Monit Assess;188(10):587, 2016 Oct. [Is] ISSN: 1573-2959 [Cp] País de publicação: Netherlands [La] Idioma: eng [Ab] Resumo: Tree cores were collected and analyzed for trichloroethylene (TCE) on a private property between a former electroplating facility in Asheville, North Carolina (USA), and a contaminated wetland/spring complex. TCE was detected in 16 of 31 trees, the locations of which were largely consistent with a "plume core" delineated by a more detailed subsurface investigation nearly 2 years later. Concentrations in tree cores and nearby soil borings were not correlated, perhaps due to heterogeneities in both geologic and tree root structure, spatial and temporal variability in transpiration rates, or interferences caused by other contaminants at the site. Several tree cores without TCE provided evidence for significantly lower TCE concentrations in shallow groundwater along the margins of the contaminated spring complex in an area with limited accessibility. This study demonstrates that tree core analyses can complement a more extensive subsurface investigation, particularly in residential or ecologically sensitive areas.

Understanding the changes in climate based on the perceptions of local communities can provide important insights for the preparedness against the unprecedented consequences of climate change. A total of 228 households in 12 different villages of Sikkim, India, were interviewed using eight climate change indicators. The results from the public opinions showed a significant increase in temperature compared to a decade earlier, winters are getting warmer, water springs are drying up, change in concept of spring-water recharge (locally known as Mul Phutnu), changes in spring season, low crop yields, incidences of mosquitoes during winter, and decrease in rainfall in last 10 years. In addition, study also showed significant positive correlations of increase in temperature with other climate change indicators viz. spring-water recharge concept (R (2) = 0.893), warmer winter (R (2) = 0.839), drying up of water springs (R (2) = 0.76), changes in spring season (R (2) = 0.68), low crop yields (R (2) = 0.68), decrease in rainfall (R (2) = 0.63), and incidences of mosquitoes in winter (R (2) = 0.50). The air temperature for two meteorological stations of Sikkim indicated statistically significant increasing trend in mean minimum temperature and mean minimum winter temperature (DJF). The observed climate change is consistent with the people perceptions. This information can help in planning specific adaptation strategies to cope with the impacts of climate change by framing village-level action plan.
