Qualitative and quantitative response of bacterial and archaeal communities to substrate-limited conditions in a two-stage anaerobic process treating swine slurry and market bio-waste

摘要

The dynamics of bacterial and archaeal communities, associated with process performance data, were investigated in a two-stage anaerobic digestion process treating swine slurry and market bio-waste and operating for 60 days under thermophilic conditions. Qualitative and quantitative responses of microbial community were monitored before and after a 15-days starvation period by Denaturing Gradient Gel Electrophoresis (DGGE) and real-time PCR techniques, respectively.
