Abstract: This study aimed to use bacterial recombinants for removing heavy metals from wastewaters in contaminated industrial sites which resulted from chemical fertilizer manufactures in Egypt, as a unique process. The significance of this study was due to heavy metals pollution which become one of the most serious environmental problems suffering society today. Ten bacterial strains belong to four genera were used in conjugation process conducted in this study, as well as, 22 transconjugants resulted from 11 mating were used in biosorption of heavy metals from factory effluents. The results appeared that some of transconjugants appeared positive hybrid efficiency in heavy metals uptake than their mid-parents, as well as, the better parent. This efficiency was exceeded one hundred percentage in relation to mid-parents, as well as, the better parent. The results indicated the higher effectiveness of bacterial recombinants than their parents in reducing the toxicity of heavy metals from factory effluents to be used as a good biosorpant agents in bioremediation experiments.
