Germination index (GI) (lines) and water soluble phenols content (histograms) of inoculated (1A and 1B) and uninoculated piles (2A and 2B) during composting. Data are means ± SD of two independent experiments. Full shape arrows indicate the time of azotobacter inoculation (after 25 and 94 days of composting); dashed arrow indicates the inoculation of P. chrysosporium spores (day 44). *Statistically significant differences (Duncan tests; P < 0.05) between inoculated and uninoculated (control) piles within each sampling time; d.w., dry weight.
