Community ecology is the study of communities formed of populations of different species. It includes the study of the interactions between species, such as mutualism, predation and competition, and the dynamics and structure of the community.
Bacterial interactions with other species can occur via small, volatile metabolites. In this protocol, volatile metabolites generated by placing two species in a two-Petri-plate system are analyzed by GC–MS after solid-phase microextraction.
