Biogas production and microbial profile estimation in bioreactor landfills

Introduction: production inhibition and to propose strategies for enhancing AD system performance, we aimed to compare the microbial community structures in leachate from different reaction periods and in solid MSW samples. Methods: A bioreactor was utilized to replicate the landfill's MSW biodegradation process. Research workers analyzed the relationship between the methanogenic process and the properties of leachate from anaerobic digestion. To investigate the underlying causes of inhibition, we compared the features and differences in the microbial community structure of leachate samples from different reaction periods and solid samples (end-state MSW and cover layer). Results: generation was mostly caused by ammonia inhibition, which reduced the activity of acetate-utilizing methanogenic archaea. The intermediate cover layer acted as a biochemical reaction zone with greater microbial diversity. Discussion: production capacity.
