Figure 1. Ammonium utilization of ΔMoglk1 and ΔMohxk1 mutants.

Figure 1

Guy11, ΔMoglk1 and ΔMohxk1 mutants were grown on MM containing 1% glucose and 100 mM ammonium. Photographs (A) were taken from one transformant of each mutant at indicated days after incubation at 30°C. Colony diameter (B) and medium pH (C) were measured at the same days. The experiment was performed with three strains for the ΔMoglk1 and ΔMohxk1 mutants, respectively; and three independent replicates provided the same results. Different letter represent difference (P<0.05) among Guy11 and ΔMoglk1, ΔMohxk1.
