Metallothionein gene(pPMT)와 Manganese Transport Gene mntA(pZH3-5)를 포함한 재조합 Escherichia coli를 이용하여 수용액상에서의 Cadmium의 선택적 제거
Abstract
Recombinant E. coli JM109(pZH3-5/pMT) harboring manganese transport gene(mntA) and metal sequestering protein, metallothionein(MT), was cultivated to accumulate cadmium in aqueous phase. Bioaccumulation followed Michaelis-Menten type kinetics. Equilibrium isotherm showed Langmuir type isotherm. The optimum pH for
