摘要

The thermophilic and mesophilic microbiota in compost produced form Esfahan municipal solid waste were examined at different stages of composting process from day zero to 28 days and was conducted in four different seasons. Some of the mesophilic bacteria observed in initial stages of composting process were gram negative Escherichia, Klebsiella, Aeromonas and Alcaligenes, and Gram positive Enterococcus and Bacillus species. After 20 Days of the composting process lower species diversity of Measophiles(only Bacillus species)were isolated, which Was most likely due to the high temperature(60-68 deg. C) Condition.
