Cesium-accumulating bacteria, strains CS98 and CS402, were isolated from soil by a radioactive autoradiographic method using 137Cs. These strains displayed the rod-coccus growth cycle and contained mesodiaminopimelic acid, mycolic acids, and tuberculostearic acids. The major menaquinone of CS98 was MK-8(H2). On the basis of these characteristics, strain CS98 was identified as Rhodococcus erythropolis and strain CS402 was classified in the genus Rhodococcus. The maximum values of cesium removal efficiencies in the liquid culture containing 10 mumol of cesium per liter for strains CS98 and CS402 were 90 and 47%, respectively. The maximum cesium contents in strains CS98 and CS402 were 52.0 and 18.8 mumol/g (dry weight) of cells, respectively. Maximum values of cesium concentration factors for strains CS98 and CS402 were 3.5 x 10(4) and 3.6 x 10(3), respectively.
