Abstract:The seed sludge originated from a methane fermentation reactor can be enriched and acclimated quickly with TA as sole carbon source for TA anaerobic degradation under nitrate respiration mode first,and then under methane fermentation mode.Through 6-week process,a 22.6mgTA/gVSS*day TA degradation rate was obtained,which was 2.1 times of the rate got from normal acclimation process.After a total of 90 days for the enrichment and acclimation,the fermentative bacteria which originally existed in the seed sludge nearly disappeared,and instead of them,the TA reductive and cleaving bacteria group was formed in the new consortium,which was confirmed by the MPN counts and roll tube counts.
