摘要This study aims to investigate the effect of bioaugmentation with enriched methanogenic propionate degrading microbial consortia on propionate fermentation under ammonia stress from total ammonia nitrogen concentration (TAN) of 3.0 g N L-1. Results demonstrated that bioaugmentation could prevent unstable digestion against further deterioration. After 45 days of 1 dosage (0.3 g dry cell weight L-1 d(-1), DCW L-1 d(-1)) of bioaugmentation, the average volumetric methane production (VMP), methane recovery rate and propionic acid (HPr) degradation rate was enhanced by 70 mL L-1 d(-1), 21% and 51%, respectively. In contrast, the non-bioaugmentation reactor almost failed. Routine addition of a double dosage (0.6 g DCW L-1 d(-1)) of bioaugmentation culture was able to effectively recover the failing digester. The results of FISH suggested that the populations of Methanosaetaceae increased significantly, which could be a main contributor for the positive effect on methane production. (C) 2017 Elsevier Ltd.
