Climate change is pushing species outside of their evolved tolerances. Plant populations must acclimate, adapt, or migrate to avoid extinction. However, because plants associate with diverse microbial communities that shape phenotypes, shifts in associations may provide an alternative source climate tolerance. Here, we show tree seedlings inoculated sourced from drier, warmer, colder sites displayed higher survival when faced drought, heat, cold stress, respectively. Microbially mediated...
There is a lack in our current understanding on the putative interactions of species phyla Acidobacteria and Verrucomicrobia with plants. Moreover, progress this area seriously hampered by recalcitrance members these to grow as pure cultures. The purpose study was investigate whether particular are avid colonizers rhizosphere. Based previous work, rhizosphere competence demonstrated for subdivision 1 groups Luteolibacter Candidatus genus Rhizospheria it hypothesized that common habitat 8...
Rapid enumeration methods based on the enzymatic hydrolysis of 4-methylumbelliferyl-beta-D-galactoside and 4-methylumbelliferyl-beta-D-glucuronide were optimized for freshwaters. The enzymes beta-D-galactosidase (GALase) beta-D-glucuronidase (GLUase) shown to be already induced in freshwaters when tested, respectively, with inducers isopropyl-beta-D-thiogalactopyranoside methyl-beta-D-glucuronide. Both activities compared, plate counts total faecal coliforms Enzymatic reference significantly...
ABSTRACT A growing number of Acidobacteria strains have been isolated from environments worldwide, with most isolates derived acidic samples and affiliated subdivision 1. We recovered 18 an alkaline soil, among which 11 belonged to the previously uncultured 6. Various medium formulations were tested for their effects on growth.
Polyketides are structurally diverse secondary metabolites, many of which have antibiotic or anticancer activity. Type I modular polyketide synthase (PKS) genes typically large and encode repeating enzymatic domains that elongate modify the nascent chain. A fosmid metagenomic library constructed from an agricultural soil was arrayed macroarray screened for presence conserved ketosynthase [β-ketoacyl (KS)] domains, present in PKSs. Thirty-four clones containing KS were identified by Southern...

Poorly soluble cobalt (II, III) oxide particles (Co3O4P) are believed to induce in vitro cytotoxic effects via a Trojan-horse mechanism. Once internalized into lysosomal and acidic intracellular compartments, Co3O4P slowly release low amount of ions (Co(2+)) that impair the viability cultures. In this study, we focused on genotoxic potential by performing comprehensive investigation DNA damage exerted BEAS-2B human bronchial epithelial cells.Our results demonstrate poorly enhanced formation...
Despite their widespread occurrence in soils, the ecology of Acidobacteria and response to environmental perturbations due human activities remain very poorly documented. This study was aimed at assessing changes diversity abundance soils contaminated with 2,4,6-trinitrotoluene (TNT) compared nonpolluted soils. The analysis communities two sites long-term short-term contamination revealed that TNT has a drastic impact on relative soil bacterial 16S rRNA gene libraries. disappearance most...
The International Thermonuclear Experimental Reactor (ITER) is an international project aimed at the production of carbon-free energy through use thermonuclear fusion. During ITER operation, in case a loss-of-vacuum-accident, tungsten nanoparticles (W-NPs) could potentially be released into environment and induce occupational exposure via inhalation. W-NPs toxicity was evaluated on MucilAir™, 3D vitro cell model human airway epithelium. MucilAir™ exposed for 24 h to metallic ITER-like milled...
Abstract Soils contain diverse living communities that provide key ecosystem functions in agroecosystems. In many systems, are positively related to the taxonomic, phylogenetic, and functional diversity of community. Despite calls incorporate microbial measures soil health, whether increased per se can predict crop health productivity has rarely been documented. Here, we used from commercial potato fields varying composition, experimentally assessed their ability promote yield under low or...
<title>Abstract</title> Background Biological chitin degradation is a major process in the ocean, governed primarily by action of microorganisms. It now known that structure and taxonomic profile chitin-degrading microbial communities change across marine biotopes, but efforts to harness turnover potential within these laboratory have seldom been attempted. In this study, we characterized prokaryotic associated with sponge <italic>Sarcotragus spinosulus</italic>, octocoral <italic>Eunicella...
This study aimed to identify factors influencing bacterial diversity in the Meuse river watershed by analyzing 42 locations sampled spring and summer 2019, combined with biweekly sampling of one mid-stream location for a year. Bacterial community composition (BCC) was assessed small (<5 µm, SF) large ($\ge$5 LF) fractions, alongside physico-chemical parameters. LF consistently exhibited greater alpha than SF. During spatial campaigns, increased downstream high discharge, BCC differed...
Abstract Background Vagococcus fluvialis is a species of lactic acid bacteria found both free-living in river and seawater associated to hosts, such as marine sponges. This has been greatly understudied, with no complete genome assembly available date, which essential for the characterisation mobilome. Results We sequenced assembled de novo sequences five V. isolates recovered from Pangenome analysis (total 17 genomes) showed high intraspecific diversity, 45.5% orthologous genes be strain...
