    Abstract

    Bacterial community profiles exhibited seasonal differences in fresh refuse collected at different times of the year as assessed by terminal restriction fragment polymorphism (T-RFLP). T-RFLP profiles in decomposed refuse showed large shifts, indicating the the majority of the microbial community was replaced as decomposition proceeded from the accelerated methane phase to the well-decomposed phase. A comparison of the solid fraction of MSW versus leachate showed that bacterial profiles are more similar as refuse is degraded. Nevertheless, large differences between the solid fraction and leachate were found in all instances, indicating that both must be considered when evaluating a landfill microbial community.
