Abstract
The indoor air in urban homes of developed countries is usually contaminated with significant levels of volatile organic carcinogens (VOCs), such as formaldehyde, benzene, and chloroform. There is a need for a practical, sustainable technology for the removal of VOCs in homes. Here we show that a detoxifying transgene, mammalian cytochrome P450 2e1 can be expressed in a houseplant, Epipremnum aureum, pothos ivy, and that the resulting genetically modified plant has sufficient detoxifying activity against benzene and chloroform to suggest that biofilters using transgenic plants could remove VOCs from home air at useful rates.
