Sphingomonas xenophaga QYY with the ability to degrade bromoamine acid (BAA) was previously isolated from sludge samples. The enhancement of BAA removal by strain QYY in sequencing batch reactors (SBRs) was investigated in this study. The results showed that augmented SBRs exhibited stronger abilities to degrade BAA than the non-augmented control one. In order to estimate the relationship between community dynamics and function of augmented SBRs, a combined method based on fingerprints (ribosomal intergenic spacer analysis, RISA) and 16S rRNA gene sequencing was used. The results indicated that the microbial community dynamics were substantially changed, and the introduced strain QYY was persistent in the augmented systems. This study suggests that it is feasible and potentially useful to enhance BAA removal using BAA-degrading bacteria, such as S. xenophaga QYY.
