Bacteria of the genus Rhodococcus were found to be able to accumulate cesium by means of active transport and nonspecific sorption on the cell surface structures. The maximum removal (up to 97%) of cesium from a medium with ammonium acetate was observed at 28 degrees C, pH 7.8-8.6, and an equimolar content (0.2 mM) of potassium and cesium ions in the medium. The most active cesium-accumulating Rhodococcus sp. strains can be used for purification of industrial wastewaters contaminated with radionuclides.
人们发现红球菌属细菌能够通过主动运输以及在细胞表面结构上的非特异性吸附来积累铯。在28摄氏度、pH值为7.8 - 8.6且培养基中钾离子和铯离子等摩尔含量(0.2 mM)的条件下,观察到从含有醋酸铵的培养基中去除铯的效率最高(可达97%)。最具活性的铯积累红球菌菌株可用于净化受放射性核素污染的工业废水。
