In this study, we examined the bioremediation potential of sulfate reducing bacteria (SRB) immobilized on zeolite in the seawater contaminated by heavy metals. Our results show that zeolite-supported SRB had enhanced abilities to remove heavy metals compared to natural zeolite. Furthermore, the removal of heavy metals was enhanced at 37℃. The removal efficiencies were 98.2%, 90.1%, 99.8% at 100 ppm of Cu, Ni, and Cr, respectively. These results demonstrate that SRB-zeolite carriers can be used as the great bioremediation material for the removal of heavy metals in marine environment.
