In soils, organic matter decomposition and stabilization largely occur as a result of microbial activity, although when present, earthworms are important drivers of the processes through their interactions with microflora which begin during organic matter digestion by earthworms. Here, the diversity of bacteria, fungi and
actinomycetes were analysed in the gut of Eudrilus eugeniae. The bacterial population was more in the midgut than foregut and hindgut region.
