Most people don’t want to live in a home filled with airborne chemicals – which is why these researchers came up with an ingenious way of cleansing indoor spaces of contaminants.

Some people may use air filters to keep offending allergens and dust particles at bay, but some hazardous compounds are too small to be trapped in these filters. Small molecules like chloroform can be found in chlorinated water, and benzene, which is a component of gasoline, builds up in our homes when we shower, boil water, or when we store cars or lawn mowers in attached garages. Both benzene and chloroform exposure have been linked to cancer.

Now researchers at the University of Washington have genetically modified a common houseplant — pothos ivy — to remove chloroform and benzene from the air around it. The modified plants express a protein, called 2E1, that transforms these compounds into molecules that the plants can then use to support their own growth.

“People haven’t really been talking about these hazardous organic compounds in homes, and I think that’s because we couldn’t do anything about them,” said senior author Stuart Strand, who is a research professor in the UW’s civil and environmental engineering department. “Now we’ve engineered houseplants to remove these pollutants for us.”

The team modified the plant with a protein called cytochrome P450 2E1, or 2E1 for short. The protein is present in all mammals, including humans. In our bodies, 2E1 turns benzene into a chemical called phenol and chloroform into carbon dioxide and chloride ions. However, since the 2E1 is only located in our livers, it is only turned on when we drink alcohol – so it’s not available to help us process pollutants in our air.
