Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis was used to study the dynamic succession of bacterial communities of anaerobic fermentation of dairy cattle manure during the microbial stationary phase. Composts were sampled during this period. Then the results showed that the population of bacterium was abundant, the superiority of that was evident, and the increment of gas production was steady. Bacterial community was with alternating growth characteristics, that is contribute to the gas production sustained and stable.
