중금속 내성이 있는 Desulfovibrio desulfuricans를 이용한 해양 환경에서의 Cu(II), Zn(II) 제거

Removal of Cupper(II), Zinc(II) in Marine Environment by Heavy Metal Resistant Desulfovibrio desulfuricans

초록

Microorganisms play a significant role in bioremediationof heavy metal contaminated seawater. In thisstudy, we reported an effective removal of Cu and Zn inmarine envionment by using Desulfovibrio desulfuricans (D. desulfuricans) which belong to sulfate reducing bacteria. D. desulfuricans showed stable growth characteristics in highsalt concentration and had resistance to heavy metals. Cu andZn was removed not only by physical adsorption on the surfaceof bacteria but also by precipitation reaction of microbialmetabolism by D. desulfuricans in seawater. In case of differentheavy metal concentration, Cu was effectively removed85% at 25 ppm and 60% at 50 ppm and Zn was effectivelyremoved 54% at 50 ppm and 46% at 200 ppm, respectively.
