Plants have been altered because they express a mammalian protein called 2E1, which allows plants to transfer harmful ingredients to compounds that support growth.
In our homes, small molecules, such as chloroform or benzene, store cars in the shower tray, boiling water, Interesting Engineering reported.
Very small toxic molecules for HEPA
These compounds tend to be too small to be captured even by HEPA air filters, but long-term exposure is associated with cancer.
"People really do not talk about these dangerous organic compounds at home, and I think we can not do anything about them," said Senior Researcher Stuart Strand, Ph.D. he said. He is a research professor at UW Civil and Environmental Engineering Department.
"Now we've prepared houseplants to clear these contaminants for us."
Scientists have taken their inspiration from nature by paying attention to a protein called cytochrome P450 2E1 or 2E1. 2E1 is available in all mammals including humans.
In our body, 2E1 is made of benzene and chloride ions called benzene phenol and chloroform.
Unfortunately, the protein is in our liver and does not allow air pollution.
"We have decided that this reaction should be outside the body of a plant, an example of the concept of" green liver, "he said.
"And 2E1 can also be useful for plants, plants use carbon dioxide and chloride ions and use phenol to form components within the cell walls."
The researchers have prepared the synthetic version of the gene and, by means of slow and complex measures, have expressed the protein of each cell in the plant, and eventually became acquainted with the pothos ivy.
Researchers have tested new GMO plants. They took a non-modified plant and a modified plant and put them in glass tubes filled with gasoline or chloroform gas.
Plants massively reduced the level of pollutants
The concentration of each contaminant in each tube was monitored over the next 11 days.
The levels for unruly plants have never changed, but the chloroform concentration for modified plants has dropped by 82% in three days.
Chloroform can not be detected almost daily. The level of benzene was also reduced in modified bottle vials, but slowly, it lasted eight days for a 75% reduction.
The team believes that plants will work in their homes, but at home requires good ventilation or a fan driven by the plant for maximum efficiency.
Researchers will now work on enhanced modifications for glue, woodsmoke and other common home formaldehyde furniture.
