The molecular weight of mVOCs in general lies between 100 and 300 Dalton. As can be seen, there are no significant differences between the molecular weight of bacterial and fungal mVOCs.


The partition coefficient (logP) is a method to measure the lipophilicity of a compound. Positive logP values indicate lipophilic compounds while negative logP values indicate hydrophilic compounds. The logP values for both fungal and bacterial mVOCs are between -1 to 2. Natural compounds have a wide range of logP between -2 to 7.


This picture shows the distribution of the chemical classification of mVOCs. Bacterial VOCs are dominated by (in descending order) aromatic compounds, alcohols, esters, nitrogen compounds and ketones. Whereas, fungal VOCs are dominated by (in descending order) aromatic compounds, terpenes, benzenoids, esters and alcohols.
