The volatilome (sometimes termed volatolome[1] or volatome[2][3][4]) contains all of the volatilemetabolites as well as other volatile organic and inorganic compounds that originate from an organism,[5][6][7]super-organism, or ecosystem. The atmosphere of a living planet could be regarded as its volatilome. While all volatile metabolites in the volatilome can be thought of as a subset of the metabolome, the volatilome also contains exogenously derived compounds that do not derive from metabolic processes (e.g. environmental contaminants), therefore the volatilome can be regarded as a distinct entity from the metabolome. The volatilome is a component of the 'aura' of molecules and microbes (the 'microbial cloud'[8]) that surrounds all organisms.
