Cleanup of trimethylamine (fishy odor) from contaminated air by various species of <i>Sansevieria</i> spp. and their leaf materials

<p>Removal of trimethylamine (TMA) by 10 different living <i>Sansevieria</i> spp. and their dried leaf materials was studied. The results showed that living <i>Sansevieria kirkii</i> was the most effective plant while <i>Sansevieria masoniana</i> was the least effective in TMA removal. Two major pathways were involved in stomata opening and epicuticular wax on the leaf surface. In the presence of TMA, the stomata opening in <i>Sansevieria</i> spp. was induced, which enhanced TMA removal under light conditions. Dried leaf powders of <i>Sansevieria</i> spp. adsorbed TMA through their waxes. Therefore, both living and non-living <i>Sansevieria</i> spp. can be effectively used for removal of TMA.</p>
