EFFECT OF CERTAIN HEAVY METALS STRESS ON METABOLIC ACTIVITIES OF SOME BACTERIAL STRAINS

+The three bacterial strains Pseudomonas aeruginosa, Bacillus firmus and Enterococcus faecalis were examined for their resistance to increasing concentrations of three heavy metal ions, namely Cd, Zn2+ and Cu2++2. The minimum inhibitory concentrations rea+2of saturated / unsaturated fatty acids. In this work the useful method for possibility of using metal resistant bacteria for removing Cd+2 from polluted effluent is the primary aim. For the pathogenisty of Ps. aeruginosa, it was tested to be used as dea
