Removal of cadmium from the cadmium solution using various microorganisms was examined. Gram-positive bacteria and actinomycetes were removed larger amounts of cadmium than other microorganisms, such as gram-negative bacteria , yeasts, and fungi. Arthrobacter nicotianae LAM 12342 can removed the largest amount of cadmium, which removed 547μmol cadmium per g dry wt. cells. The removal of cadmium using A. nicotianae was affected by the solution pH, concentration of cadmium, cell amount and temperature. Theremoval of cadmium was very rapidly.
