A continuous culture of Desulfovibrio on a medium containing mercury and copper ions

It appeared that in such a culture the metals are continually rendered harmless by the precipitation of metal suphides, while in batch cultures in the same medium no growth takes place. The...

Description
Summary:The effects of the toxic metals Hg and Cu on the growth of Desulfovibrio in a continuous culture was studied. It appeared that in such a culture the metals are continually rendered harmless by the precipitation of metal suphides, while in batch cultures in the same medium no growth takes place. The overflow of the continuous culture no longer contains any toxic metal, as is proved by microbial growth occurring after addition of some substratum. Microbiological process s could be used to render toxic metals innocuous, to remove them from polluted water, and to fix them as sulphides.
