Abstract
|
|
|
|
In this study, A bacterium with an ability to resist toxic heavy metals was isolated from reeds in wetland. The isolated strain was identified to Alcaligenes sp. KC-1 by 16S rDNA sequencing. Heavy metals such as Pb, Cr6+, Cd, Zn and Cu were supplied to media. The ecotoxic treat of the heavy metals on the growth of strain KC-1 was performed when the isolated strain Alcaligenes sp. KC-1 cultured with Cu ranging from 0 mM to 20 mM. It showed the resistance of EC50(7.34 mM) and cell growth (OD600 nm : 0.83 after 42 hours) when it was cultured in Cu.
