FIG 3.

H₂O₂ production by M. gallisepticum strains and glp mutants grown in glycerol as the carbon source. The concentrations of H₂O₂ were measured in the growth media of M. gallisepticum strains grown in glycerol by using Merckoquant peroxide test strips. R_low was also grown without the addition of glycerol (−). Statistical significance was determined by ANOVA with a Newman-Keuls post hoc test for multiple pairwise comparisons. Different capital letters above the data indicate statistically significant differences (P < 0.05).
