Ethylene removal evaluation and bacterial community analysis of vermicompost as biofilter material

► The vermicompost with indigenous microorganisms as bed material is evaluated for ethylene removal through batch test and biofilter experiment. ► Temporal and spatial dynamics of bacterial community in the vermicompost-biofilter under different ethylene loads are also characterized. ► The vermicompost is a promising bed material for ethylene degradation. ► Pseudomonads and Actinobacteria are predominant during ethylene biofiltration in the vermicompost-biofilter.
