Role of vermicompost chemical composition, microbial functional diversity, and fungal community structure in their microbial respiratory response to three pesticides

► Organic wastes from different origins were bioconverted into four vermicomposts. ► Vermicomposts' chemical features and microbial functional diversity were explored. ► Response of the vermicomposts' microbiota to three pesticides was investigated. ► The vermicompost' chemical features affected its microbial functional diversity. ► Functional diversity of the microbiota was related with its response to pesticides.
