Fig. 2.

Percentages of end-products of anaerobic nitrate reduction by B. licheniformis strains in TSB and mineral medium with 30 mM glucose (MM), amended with 10 mM nitrate. Error bars represent standard deviation (n = 3). The larger error bars for LMG 7559 result from differences in one of the three replicates. Measured concentrations of ammonium were corrected for loss through assimilation. N deficit in TSB experiments was attributed to ammonium production, which could not be measured, and visualized as such for convenience of comparison
