초록

In this study, we have developed a microbe-carrier that combined Desulfovibrio desulfuricans and zeolite for removal of Zn and As in contaminated seawater. Desulfovibrio desulfuricans, one of the sulfate-reducing bacteria (SRB) microorganism was exhibited stable growth characteristics in highly salted water and strong resistance to Zn and As contaminated seawater. Moreover, zeolites are one of the most useful carrier to remove heavy metals from wastewaters. The results showed that SRB immobilized zeolite carrier can enhance removal ratio of Zn and As. In addition, heavy metals tended to be better removed in medium at conditions of 37 °C. In case of heavy metal concentration, they were effectively removed ranging from 50 to 100 ppm. These results show that SRB-zeolite carriers hold great potential to remove cationic heavy metal species from industrial wastewater in marine environment.
