Microbial community dynamics in mesophilic anaerobic reactors exposed to overfeeding
Résumé
The bacterial and archaeal communities’ genetic structures of four mesophilic CSTRs were monitored during a gradual overfeeding experiment aiming at causing acidosis. The 16S rRNA T-RFLP patterns showed overt changes in the structure of both microbial communities during acidosis installation (decreasing of the reactor pH value) and after process recovery. The lower the pH value during the acidosis, the more the composition of the microbial community was altered between the beginning and the end of the experiment.
