Various microorganisms emit volatile organic compounds (VOCs, or specifically microbial VOCs (MVOCs)) as part of their metabolism or as a means of defense against changes in their environment. MVOCs, which have low boiling points and molecular weights, have been widely studied for various applications. This field has emerged as volatilomics, a subcategory of proteomics, which studies the MVOC emissions of microorganisms and the pathways involved in these emissions. Bacterial MVOCs are more structurally diverse than fungal MVOCs, and hence, have piqued the interests of researchers. Bacterial MVOCs can be classified as hydrocarbons, alcohols, ketones, terpenes, benzenoids, pyrazines, acids, and esters. In this study, MVOC was used to define the volatile emissions of bacteria.

Various microorganisms emit volatile organic compounds (VOCs, or specifically microbial VOCs (MVOCs)) as part of their metabolism or as a means of defense against changes in their environment. MVOCs, which have low boiling points and molecular weights, have been widely studied for various applications. This field has emerged as volatilomics, a subcategory of proteomics, which studies the MVOC emissions of microorganisms and the pathways involved in these emissions. Bacterial MVOCs are more structurally diverse than fungal MVOCs, and hence, have piqued the interests of researchers. Bacterial MVOCs can be classified as hydrocarbons, alcohols, ketones, terpenes, benzenoids, pyrazines, acids, and esters. In this study, MVOC was used to define the volatile emissions of bacteria. Furthermore, because of the recent discoveries on bacterial species and strains, there is a need to expand the current MVOC database. Aside from this, MVOCs can be emitted by bacteria when they are under stress or when they are exposed to changes in their environment, such as the presence of other bacteria or other species. This study then aims to identify the volatiles being emitted by the bacteria understudy.
