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 metal-contaminated soils show various de- grees of resistance to cadmium; for example, Bacillus sp. J119 was resistant to cadmium at a concentration 20 mg L
