A Tasmanian devil with stinky feet.

•	Role in Odor:

3M3SH is one of the most potent components of human body odor, especially in the underarm area. It’s formed when skin bacteria break down odorless precursors in sweat, releasing this highly volatile and foul-smelling compound. • Smell Profile: Described as sulfurous, onion-like, or sweaty, 3M3SH is notorious for its sharp, persistent scent—even in small amounts.

⸻

In your Tasmanian devil, the presence of 3M3SH adds a realistic and intense layer to the onion-scented, silver-colored foot odor.

Bacteria: Staphylococcus epidermidis. Acetobacteria. Corynebacteria. Gluconobacteria. Micrococcus luteus.

Fungi: Trichophyton mentagrophytes. Candida albicans. Aspergillus niger.

Others: Isovaleric acid. Acetic acid. 3M3SH. Methanethiol. Dimethyl disulfide.

A common skin-dwelling bacterium, Micrococcus luteus is often associated with unpleasant body odors, especially in areas exposed to sweat and synthetic fabrics. It breaks down fatty acids, amino acids, and other compounds found in secretions, producing short-chain, smelly molecules responsible for that stinky body odor scent.

Interestingly, M. luteus also plays a role in degrading environmental pollutants, making it a double-edged microbe—both foul-smelling and ecologically useful.

In Tasmanian devils, it likely contributes to the sharp, onion-like foot odor, particularly when combined with other bacteria and compounds like 3M3SH and isovaleric acid.
