Reaction Steps

FIG. 12 illustrates perchlorate reduction by DM-17 grown in BMS medium. The experiment was initiated with 10 mM sodium perchlorate and either 0, 0.1, 1.0, 10 or 100 mM sodium nitrate, resulting in nitrate to perchlorate ratios of 0×, 0.01×, 0.1×, 1.0× and 10×, respectively. Data points represent the mean of triplicate measurements (n=3). FIG. 13 illustrates perchlorate reduction by DM-17 grown in BMS medium. The experiment started with 1 mM sodium perchlorate and either 0, 0.1, 1.0, 10 or 100 mM sodium nitrate, resulting in nitrate to perchlorate ratios of 0×, 0.1×, 1.0×, 10× and 100×, respectively. Data points represent the mean of triplicate measurements (n=3). FIGS. 12 and 13 show that perchlorate reduction by DM-17 was inhibited by high nitrate concentrations. FIG. 12 shows that only the treatment with 100 mM nitrate (10×) was inhibitory, since the 0×, 0.01×, 0.1×, and 1× treatments all removed greater than 99.9% of the initial perchlorate within 48 h. The 10× (10 mM) treatment only reduced 22.5% of the initial perchlorate by 48 h. Likewise, FIG. 13 shows that only the 100 mM nitrate (100×) was inhibitory, since the 0×, 0.1×, 1.0×, and 10× treatments all removed greater than 99% of the initial perchlorate by 48 h. The 100× treatment only reduced 35.1% of the initial perchlorate within 48 h.
