FIG. 2.
Effect of MSX on growth and atrazine degradation by resting cells of Pseudomonas sp. strain ADP. (A) Growth curves of Pseudomonas sp. strain ADP growing on ammonium as the sole nitrogen source with the addition of 1 mM MSX (closed triangles), 0.8 mM MSX (open squares), 0.5 mM MSX (closed squares), 0.2 mM MSX (open circles), or no MSX (closed circles, −MSX). The arrowhead indicates the time of addition of MSX. (B) Resting cell assay of atrazine degradation by Pseudomonas sp. strain ADP grown on ammonium (closed circles, −MSX) or ammonium and 0.5 mM MSX (open circles). Symbols represent the averages of the results from four independent experiments. Error bars represent standard errors of the averages.
