The molecular weight of mVOCs in general lies between 100 and 300 Dalton. As can be seen, the molecular weight of fungal mVOCs is slightly lower than that of bacterial mVOCs; suggesting that volatiles emitted by fungi tend to be smaller than volatiles emitted by bacteria. |

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 lies between -1 to 2. On the contrary, natural compounds have a wide range of logP lies between -2 to 7. |

This picture shows the distribution of the chemical classification of mVOCs. Bacterial VOCs are dominated by (in descending order) alkenes, alcohols, ketones, terpenes, benenoids, pyrazines, acids and esters. Whereas, fungal VOCs are dominated by (in descending order) alcohols, benzenoids, aldehydes, alkenes, acids, esters and ketones. |
