We developed a microwell plate, high-throughput, screening method aimed at quantitating the tolerance of a panel of Gram-positive and Gram-negative bacteria to metals (Frankia sp., Escherichia coli, Cupriavidus metallidurans, Rhizobium leguminosarum, and Streptomyces scabies). Microbial viability was quantified using MTS; a tetrazolium salt converted to a(More)
Alders have already demonstrated their potential for the revegetation of both mining and industrial sites. These actinorhizal trees and shrubs and the actinobacteria Frankia associate in a nitrogen-fixing symbiosis which could however be negatively affected by the presence of heavy metals, and accumulate them. In our hydroponic assay with black alders,(More)
Canadian oil sands tailings are predominately sodic residues contaminated by hydrocarbons such as naphthenic acids. These conditions are harsh for plant development. In this study, we evaluated the effect of inoculating roots of Alnus viridis ssp. crispa and Alnus incana ssp. rugosa with ectomycorrhizal fungi in the presence of tailings compounds. Seedlings(More)
