In this study, the aerobic activated sludge for skatole removal was enriched from pig slurry in three parallel sequencing batch reactors. The sludge system exhibited a satisfactory performance for skatole removal during the 40 days operation. High-throughput sequencing results showed that the α-diversity remained unchanged before and after the operation process. However, the structures of bacterial and fungal communities notably shifted. Particularly, increased to be the major bacterial genus from 2.15 ± 0.76% (day 0) to 23.80 ± 24.36% (day 40), and became the major fungal genus from 1.20 ± 0.48% (day 0) to 37.17 ± 7.47% (day 40). These results indicated that and might participate in skatole removal in sludge systems, though both genera were not reported to be able to degrade skatole. This is the first study describing skatole-degrading bacterial and fungal communities in the enrichment from pig slurry to the best of our knowledge, providing important guidance for skatole control and bioremediation.
