简介：
Overview
This study investigates host-microbiome interactions using compost microcosms in Caenorhabditis elegans, providing an in-lab method for exploring relationships between environmental microbial diversity and the gut microbiome of worms. The method allows for natural-like conditions without isolating wild worms or relying on limited synthetic communities.
