Abstract

Heavy metal pollution has been become the most serious in irrigated area of China with waste water, occupying about 64% the area[1], These heavy metals, such as cadmium(Cd), mercury(Hg) and lead(Pb), can enter into the food chain and do great harm to human health. Cyanobacteria have been found their capability of riching heavy metals in marine and they possess unique adaptation to various ecosystems. More and more people consider that cyanobacteria are biotechnically potential environmental bioremediator[2,3].

Key words

heavy metals tolerance transgenic cyanobacteria gene expression metalloproteins(metallothioneins)
