Using glucose as cosubstrate, activated sludge that could effectively biodegrade 40 mg/L 2-chlorophenol was successfully domesticated in sequencing batch reactors. To acclimate the sludge, 2-chlorophenol was increased stepwise from 0 to 40 mg/L. High-throughput sequencing revealed that the microbial community richness increased during the first 5 days of acclimation to 5 mg/L 2-chlorophenol and then decreased after another 20 days as 2-chlorophenol was increased.

High-throughput sequencing (HTS) analysis revealed that the community richness initially increased for 5 days and then decreased after another 20 days with the increase of 2-CP. The original sludge obtained from water resource recovery facility had the highest diversity.
