Biological activity was most intensive in Run C and was least intensive in the control run. ?The concentration of H2S in control run was high during posting processes. ?The maximal emissions of H2S were mg/L in the control run, mg/L in run A, mg/L in run B, and mg/L in run C ?Therefore, inoculation is useful for controlling H2Semission. 67891011121314150 20 40 60 80 100 120 140C o m p o s t i n g T i m e /hLogCFU/gControlRun ARun BRun CThe following figure shows the total heterotroph counts profile in the posting process For the total heterotroph counts: ? A clear difference was observed between the control run and the three inoculation Runs ? The microanism population in Run A reached a peak time with log10CFU equal to 10 at day 2 ? The population in Run B equal to at day 4 ? The population in Run C equal to 10 at day 3 ? The population in the control run equal to at day 7 . Discussion The following formula shows the first stage microbial kiics: ? is rate of hydrolysis of solid substrat
