Vicia sativa –rhizospheric bacteria interactions to improve phenol remediation

摘要: The aim of this study was to evaluate whether the interaction Vicia sativa with a bacterial strain capable using phenol as sole carbon and energy sources can moderate adverse effects pollutant in plant tissues. A identified Bacillus sp., isolated from heavily polluted environment, inoculated at different stages growth. In root elongation assay, seeds showed higher values relative germination index than uninoculated ones presence high concentrations. Thus, common vetch–Bacillus sp. association could be important first development allowing grow highly environments. Besides, removal largely accelerated phenol-spiked soils, after 48 h treatment uninoculated/inoculated plants rather by adsorption or biodegradation strain. Peroxidase ascorbate peroxidase activities increased significantly plants, while superoxide dismutase activity, chlorophyll, malondialdehyde, H2O2 levels aerial parts remained unaltered treated pollutant, demonstrating that efficient response oxidative damage did not depend on inoculation.
