3.3. MIC of cadmium against cadmium-resistant PGPR
Micrococcus sp. and Klebsiella sp. were found to exhibit cad- mium resistance. The MIC values of cadmium for Micrococcus sp. and Klebsiella sp. were 1000 and 800 mM, respectively. Bacteria isolated from heavy metalcontaminated soils show various degrees of resistance to cadmium; for example, Bacillus sp. J119 was resistant to cadmium at a concentration 20 mg L
