摘要：
Cupriavidus metallidurans CH34 cells grown under sulfate-limited conditions accumulated up to six times more selenate than cells grown in sulfate-rich medium. The products of selenate reduction detected by X-ray absorption spectroscopy, electron microscopy, and energy-dispersive X-ray analysis did not define this strain as being a good candidate for bioremediation of selenate-contaminated environments.
