摘要：

Cadmium ions are bacteriocidal, resulting in exponential killing that starts immediately after exposure. We have shown that pretreatment with sublethal concentrations of cadmium induces cadmium tolerance. Protection against cadmium killing can also be obtained by preincubation at elevated temperatures, known to induce the heat-shock response. However, in contrast to pretreatment at elevated temperatures, exposure to sublethal cadmium concentrations does not induce thermotolerance.
