Abstract: The seed sludge originated from a methane fermentation reactor was
enriched and acclimated with TA as sole carbon source under nitrate respiration
mode first for 6 week, and then can be turned to methane fermentation
conditions. After 6 weeks processing, the specific rate acclimation. 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
consortia, which was confirmed by the MPN counts and roll tube counts. Compared
with the control experiment, the acclimation period can be shortened by about
50%.
