RL-enhanced bioremediation had a significant effect on aerobic TCS degradation.
Controlling environment factors can increase the efficiency of bioremediation.
60 μg/g TCS decreased community diversity and abundance of water-sediment system.
Alpha-proteobacteria predominated in the TCS-degrading system.
Sphingobacteria and Beta- and Delta-proteobacteria were sensitive to TCS toxicity.
