(A) Populationof fast-growing microbes on nutrient agar plates in CFUs.(B) Populationof actinomycetes on humic acid- vitamin agar plates in CFUs. Plates were incubated as described in Materials and Methods. The chemical treatments were administered at 100nmole/g. Open bar: water-treated (control); Solid bar: ATP-treated; gray bar: ATPgS-treated; Hatched bar: ADP-treated; Dotted bar: AMP-treated; Waved bar: phosphate-treated. Error bars indicate the standard deviation of three independent plates. * and **represent statistically significant differences (p < 0.05 and p < 0.01, respectively) compared with the control.
