%X The growth characteristics and the decontamination of heavy metals in analogous heavy metals wastewater by transgenic Synechococcus sp. PCC 7002 with mouse metallothionein-I gene were studied. The results show that transgenic Synechococcus sp. PCC 7002 not only has a higher tolerance to heavy metals, but also has a higher growth rate than wild strain. The concentration of Cd2+, Pb2+ and Hg2+ decreases with the progress of cultivation, and its maximum decreasing extent occurs at 1 - 3 day. After three days of cultivation, the absorption of Cd2+, Pb2+ and Hg2+ by transgenic Synechococcus sp. PCC 7002 is 10.75, 58.89 and 112.61 mg g(-1) of dried cells respectively, which is 3.16, 2.18 and 100.45 times higher than wild cells. The mono-factor and overall model developed fit the experiment data well.
