Halite endoliths in the Atacama Desert represent one of most extreme ecosystems on Earth. Cultivation-independent methods were used to examine functional adaptations microbial consortia inhabiting halite nodules. The community was dominated by haloarchaea and analysis attributed autotrophic CO2 fixation unique cyanobacterium. assembled 1.1 Mbp genome a novel nanohaloarchaeon, Candidatus Nanopetramus SG9, revealed photoheterotrophic life style low median isoelectric point (pI) for all...
Summary In hyperarid deserts, endolithic microbial communities colonize the rocks’ interior as a survival strategy. Yet, composition of these and drivers promoting their assembly are still poorly understood. We analysed diversity community endoliths from four different lithic substrates – calcite, gypsum, ignimbrite granite collected in zone Atacama Desert, Chile. By combining microscopy, mineralogy, spectroscopy high throughput sequencing, we found to be highly specific substrate, although...
Planktonic Nostocales cyanobacteria represent a challenge for microbiological research because of the wide range cyanotoxins that they synthesize and their invasive behavior, which is presumably enhanced by global warming. To gain insight into phylogeography potentially toxic from Mediterranean Europe, 31 strains Anabaena (Anabaena crassa, A. lemmermannii, mendotae, planctonica), Aphanizomenon (Aphanizomenon gracile, ovalisporum), Cylindrospermopsis raciborskii were isolated 14 freshwater...
Under extreme water deficit, endolithic (inside rock) microbial ecosystems are considered environmental refuges for life in cold and hot deserts, yet their diversity functional adaptations remain vastly unexplored. The metagenomic analyses of the communities from two rock substrates, calcite ignimbrite, revealed that they were dominated by Cyanobacteria, Actinobacteria, Chloroflexi. relative distribution major phyla was significantly different between substrates biodiversity estimates, 16S...
Polybrominated diphenyl ethers are persistent disrupters assimilated by organisms, yet little is known about their link to plastic ingestion and health effects. In an experiment, two groups of yellow-legged/lesser black-backed gulls (Larus michahellis/Larus fuscus) were fed plastics with BDE99 assess leaching into brain, preen oil, liver fat tissues evaluate effects on stress parameters. Although most was regurgitated, we observed a clear relation between chemical leaching. exhibited higher...
Abstract The biochemical responses of rock-inhabiting cyanobacteria towards native environmental stresses were observed in vivo one the Earth’s most challenging extreme climatic environments. cryptoendolithic cyanobacterial colonization, dominated by Chroococcidiopsis sp., was studied an ignimbrite at a high altitude volcanic area Atacama Desert, Chile. Change carotenoid composition (red-shift) within transect through dominant microbial community (average thickness ~1 mm) unambiguously...
The Atacama desert is amongst the oldest and driest deserts in world, its hyperarid core described as ‘the most barren region imaginable’. In this study, we describe for first time endolithic microbial communities composed by eukaryotic microorganisms, such melanized fungi algae, colonizing interior of gypsum crusts collected zone desert. Melanin pigments present cell walls have been studied Raman microspectroscopy. Analyses performed directly crust sustaining colonisation on thin sections...
Cyanobacteria exposed to high solar radiation make use of a series defense mechanisms, including avoidance, antioxidant systems, and the production photoprotective compounds such as scytonemin. Two cyanobacterial strains genus Chroococcidiopsis from Atacama Desert – which has one highest levels on Earth- were examined determine their capacity protect themselves direct photosynthetically active (PAR) ultraviolet (UVR): UAM813 strain, originally isolated cryptoendolithic microhabitat within...
Abstract Cyanobacteria inhabiting extreme environments constitute a promising source for natural products with biotechnological applications. However, they have not been studied in-depth this purpose due to the difficulties in their isolation and mass culturing. The Atacama Desert suffers one of highest solar irradiances that limits presence life on its hyperarid core endolithic microbial communities supported by cyanobacteria as primary producers. Some these are known produce scytonemin,...
Abstract. Endolithic microhabitats have been described as the last refuge for life in arid and hyper-arid deserts where has to deal with harsh environmental conditions. A number of rock substrates from Atacama Desert, colonized by endolithic microbial communities such halite, gypsum crusts, gypcrete, calcite, granite ignimbrite, characterized compared using different approaches. In this work, three are described, each one a particular origin architecture, found within lithic substrate known...
Rhipicephalus ticks are competent vectors of several pathogens, such as Spotted Fever Group Rickettsiae (SFGR) and many Babesia species. Within this genus, different R. sanguineus s.l. lineages show an unequal vector competence resistance regarding some pathogenic strains. Current literature supports that tick endosymbionts may play essential role in the transmission ability a vector. Indeed, microbial community seems to be dominated by Coxiella-like (CLE). Still, their co-evolutionary...
Fibers are found in all environments. However, the impact of their presence on ecosystems and human health is not yet well understood, especially case atmosphere. In this work, we presented evidence that fibers traveling through atmosphere act as vectors to spread microorganisms. Here, investigated viable microorganisms collected within beyond planetary boundary layer during flights C-212 aircraft over Central Spain. total, seven fibers, six which transported microorganisms, were isolated...
Cyanobacteria are key organisms in the Antarctic ecosystem, but primary succession of its communities recently deglaciated soils remains poorly understood. In this study, we surveyed cyanobacterial with an in-depth Next Generation Sequencing approach three glacier forefields. Despite similar physicochemical characteristics soils, did not find a common pattern distribution at finest level taxonomic resolution. However, metabarcoding analysis revealed community 14 identical sequences all...
