Fig. 2-nonenal formation in an old-person skin
Body odor is a unique characteristic of each individual. Our body aroma could change with shifts in diet, physical activity, and age. Previous research has demonstrated that people are able to correctly identify the age of an unknown person based exclusively on their body odor [1]. This research confirmed that 'aging odor' or 'old person smell' does really exist. Moreover, Japanese researchers identified the volatile molecule that is positively correlated with age and significantly detectable for the people over 40 year old. [2]
This molecule is an unsaturated aldehyde 2-nonenal with a characteristic scent described in the literature as a combination of orris, cucumber, and fat.[3] According to Haze et al. [2] the 2-nonenal is formed by oxidative degradation of skin surface lipids, accelerated by lipid peroxides. However, it is not clear if these fatty acids on the skin are initially degraded by skin microbiome or other agents [2].

Motivation
The deterioration of personal odor due to aging may be a serious social problem for some people which would like to keep youth body odor. Moreover, the 2-nonenal smell is mostly perceived as unpleasant, thus people with body odor marked with this compound may undergo unfriendly reactions based on their odor. Therefore, iGEM Paris Bettencourt Team decided to study the 2-nonenal relationship with the human skin microbiome in order to help aged people neutralize their body odor.
