Fig. 3 Effect of initial As(V) concentration on As(V) reduction rate in serum bottles inoculated with CN-0 or CN-8 at initial glucose concentrations of 5 mM. Rates of As(V) reduction for two environmental isolates from other studies are shown for comparison. Experiments with initial As(V) concentrations of 600 µM were replicated (triplicates on CN-8, duplicates on CN-0) and error bars denote one standard deviation about the mean. Error bar for CN-0 is smaller than symbol
