Implication

Randomized trial examines how earthworm species alter microbial outcomes in sewage sludge, suggesting implications for treatment safety and effectiveness.

Key Points

The study aims to investigate how different earthworm species affect bacterial and fungal communities in sewage sludge through gut transit.
Examined gut transit effects of three epigeic (Eisenia andrei, E. fetida, Dendrobaena hortensis) and two anecic (Lumbricus friendi, L. terrestris) earthworm species.
Utilized 16S rRNA and ITS amplicon sequencing combined with multivariate and functional prediction analyses.
Compared microbial communities between fresh sewage sludge and earthworm cast samples.
Earthworm gut transit led to significant species-specific changes in bacterial and fungal community composition and diversity.
Functional analyses showed shifts in bacterial metabolic potential and fungal trophic functions, enhancing biosynthetic and decomposer roles.
Pathogen profiles exhibited selective changes influenced by the earthworm species, rather than uniform suppression.
