文摘

•: A microbial community able to degrade 2,4-D and dicamba was selected.
•: A horizontal-multistage-packed-bed biofilm reactor was used for biodegradation studies.
•: Operational conditions affect bacterial count and diversity of the microbial community.
•: Bacterial diversity changes were observed by massive sequencing of metagenomic DNA.
•: Microbial community acclimation was observed by changes in specific degradation rates.
