Scientists have converted plastic bottles into vanilla flavoring using genetically engineered bacteria. According to research published in the journal Green Chemistry, genetically engineered E-Coli bacteria has been used to convert terephthalic acid (TA) from plastic waste into vanillin. Joanna Sadler, co-author of the study, said, “This is the first example of using a biological system to upcycle plastic waste into a valuable industrial chemical and it has very exciting implications for the circular economy.” Related: Scientists create super-enzyme to degrade plastic bottles 6 times faster Terephthalic acid is a basic compound obtained when plastic bottles are broken down by enzymes.
