Monitoring of uranium-phosphate biomineralisation with Serratia.
(a) With glycerol phosphate as the electron donor and fumarate as the electron acceptor, increasing optical density and U mineral precipitation. Each point represents the average of three replicates with error bars ± 1 standard deviation. (b) With glycerol phosphate and U(VI) as the sole electron acceptor and with comparatively delayed onset of cell growth and U precipitation. This control sample was a single measurement.
