[Development of copper tolerance in cyanobacteria subjected to repeated copper intoxication].
Experiments on cyanobacterial cultures showed that initial exposure to copper at concentrations of 0.01-0.05 mg/l not only has a direct toxic effect, but also significantly modifies the copper tolerance of cyanobacteria for repeated exposure. The response to repeated exposure and the mechanism of tolerance depend on the strength of the initial effect of copper and the extent of heterogeneity of the initial cyanobacterial population.
