In the present study, three chromium resistant bacterial strains (CrT-1, CrT-2, CrT-3) which could resist veryhigh concentration of K2CrO4 (up to 40 mg ml-1 on nutrient agar plates and 10 mg ml-1 in acetate-minimalmedium) were used to inoculate the sunflower seeds both as control and under chromium stress. Cr(VI)caused severe reduction in different growth parameters (seedling ...
