This study aims to investigate the colonization of poplar by the endophyte Pseudomonas putida W619 and its capacity to promote plant growth. Poplar cuttings were inoculated with P. putida W619 (wild-type or gfp-labelled). The colonization of both strains was investigated and morphological, physiological and biochemical parameters were analyzed to evaluate(More)
Numerous microorganisms have been isolated from trinitrotoluene (TNT)-contaminated soils, however TNT tends to persist, indicating that the microbial biomass or activity is insufficient for degradation. Deep-rooting trees at military sites have been found to take-up contaminants from groundwater, and the extensive root and endosphere provide ideal niches(More)
Microbe-assisted phytoremediation is particularly effective for organic pollutants. The leguminous shrub Cytisus striatus (Hill) Rothm. has been proposed as a candidate species for the rhizoremediation of hexachlorocyclohexane (HCH)-contaminated sites. The aim of this study was to improve the performance of this species using microbial inoculants. C.(More)
We investigated the effect of different growth substrates, frequently used during production of Arabidopsis thaliana seeds, on the endophytic assemblage of this plant. Arabidopsis thaliana was grown on sand and on a mixture of sand and potting soil. Seeds harvested on both substrates were sown again on the same substrate until the radicle emerged and until(More)
Phytoextraction has been reported as an economically and ecologically sound alternative for the remediation of metal-contaminated soils. Willow is a metal phytoextractor of interest because it allows to combine a gradual contaminant removal with production of biomass that can be valorized in different ways. In this work two willow clones growing on a(More)
We report the draft genome of Raoultella ornithinolytica TNT, a Gram-negative bacterium of the Enterobacteriaceae isolated from military soil in Belgium. Strain TNT uses nitrite released from trinitrotoluene (TNT) for growth and is a potent plant growth promoter. An analysis of its 5.6-Mb draft genome will bring insights into TNT degradation-reinforcing(More)
Cultivable bacterial strains associated with field-grown Brassica napus L. (soil, rhizosphere and roots) from a trace elements (Cd, Zn and Pb) contaminated field and a non-contaminated control field were characterized genotypically and phenotypically. Correspondence analysis of the genotypic data revealed a correlation between soil and rhizosphere(More)
We report here the draft genome of Enterobacter aerogenes, a Gram-negative bacterium of the Enterobacteriaceae isolated from Cucurbita pepo root tissue. This bacterium shows 2,2-bis(p-chlorophenyl)-1,1-dichloroethylene (DDE)-degrading potential and plant growth-promoting capacity. An analysis of its 4.5-Mb draft genome will enhance the understanding of DDE(More)
Phytoremediation is a promising technology to clean-up contaminated soils based on the synergistic actions of plants and microorganisms. However, to become a widely accepted, and predictable remediation alternative, a deeper understanding of the plant-microbe interactions is needed. A number of studies link the success of phytoremediation to the(More)
Microbacterium spp. isolated from heavy metal (HM)-contaminated environments (soil and plants) can play a role in mobilization processes and in the phytoextraction of HM. Here, we report the whole-genome sequences and annotation of 10 Microbacterium spp. isolated from both HM-contaminated and -noncontaminated compartments.
