Two Cd-resistant bacterial growth strains MA-9 (Aeromonas) and MA19 (affinities uncertain), which were isolated from ICI effluents, were used to inoculate seeds of Triticum aestivum (wheat) and Helianthus annuus (sunflower). Both inoculated and non-inoculated seeds were germinated and grown under different concentrations(0, 1, 2 and 3 mM) of CdCl2 for 10 days. Under Cd-stress conditions, bacteria-inoculated plants had better germination and growth than non-inoculated treatments. Bacterial growth enhancement of seedlings was associatedwith reduced Cd uptake.
