Microbiology techniques are methods used for the study of microbes, including bacteria and microscopic fungi and protists. They include methods to survey, culture, stain, identify, engineer and manipulate microbes.
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.
