A phytoremediation was selected to mitigate fishy odor or trimethylamine (TMA) that occurs from seafood industry or fresh market. A synthetic TMA chemical was used for fishy odor. For this research, eight types of potted plants (Prickly pear cactus, Dracaena sanderina Sander, Dieffenbachia camilla, Tradescantia spathacea, Peperromia magnoliifolia, Cholorophytum comosum, Cereus hexagonus (L.) Mill, and Scindapsus aureus) were selected as the representative of potted plant to remove TMA under light and dark conditions. The results showed that S. aureus had the highest TMA removal efficiency under light conditions at 72 h (> 95%). However, it had very low efficiency under dark conditions. This implied that S. aureus should be applied in the places having light sources all day. On the other hand, cactus type (C. hexagonus (L.) Mill. and Prickly pear cactus) had high TMA removal efficiency under both light and dark conditions at 72 h (> 90%). These plants might be more suitable to apply in a real system containing light and dark conditions.
