Actinorhizal plants are ecologically and economically important. Symbiosis with nitrogen-fixing bacteria allows these woody dicotyledonous to colonise soils under nitrogen deficiency, water-stress or other extreme conditions. However, proteins involved in xerotolerance of symbiotic microorganisms have yet be identified. Here we characterise the polyethylene glycol (PEG)-responding desiccome from most geographically widespread Gram-positive plant symbiont, Frankia alni, by next-generation...
Purpose: To assess exopolysaccharides (EPS) of Bacillus siamensis CV5, isolated from irradiated roots Cistanche violacea, for their induction by ionizing radiation (IR) and antioxidant radioprotective power.Materials methods: Isolated bacteria the C. violacea were screened EPS production. The most EPS-producing bacterium was selected response surface methodology (RSM) applied to elucidate IR dose effects on Gamma irradiation morphology functional groups studied using microscopy Fourier...
Bacterial communities associated with roots of Panicum turgidum, exposed to arid conditions, were investigated a combination cultural and metataxonomic approaches. Traditional culture-based techniques used 32 isolates from the irradiated identified as belonging Actinobacteria, Bacteroidetes, Firmicutes Proteobacteria phyla. Four actinobacterial strains shown be ionizing-radiation (IR)-resistant: Microbacterium sp. PT8 (4.8 kGy (kGy)), Micrococcus PT11 (4.4 kGy), Kocuria rhizophila PT10 (2.9...
In this work, a native exopolysaccharide (nEPS) produced by Halomonas desertis G11 isolated from Tunisian extreme environment was modified gamma irradiation. Characterization as well the antioxidant and antitumor activities of nEPS its gamma-irradiated derivatives (iEPSs) were comparatively evaluated. vitro in vivo potentials determined using different methods through enzymes. The activity checked against human colon cancer cell line. Analyses complete genome sequence carried out to identify...
