Did he make a breakthrough on the way to a better environment? my cent. Thanks to the rest of the plastic bottles, Vdcm was able to produce vanilla extract, which is widely used in food and cosmetics. In addition, the demand for the vanilla fruit, from which the vanilla is made, is boosting the supply, so this method of recycling plastic may soon be very attractive.
Every minute, about one million plastic bottles are sold around the world, and this, in turn, greatly burdens the environment. Only about 14 percent of it is recycled, so the vast majority of it is sold. After plastic bottles, they represent the most common type of plastic when appreciated.
In addition, recycled plastic bottles can only be turned into opaque fibers to make clothes and carpets. Therefore, scientists have been trying for a long time how to re-cut plastic in the dark. And they drank you great news. He developed two enzymes that break down the polyethylene terephthalate polymer from which plastic bottles are made in its own volume, terephthalic acid.
The researcher used this to convert it into vanillin with the help of modified Escherichia coli bacteria. The process, according to the Guardian, led to the fact that scientists swallowed the substance to 37 degrees Celsius, thanks to bacteria and other chemical reactions that converted 79 percent of the acid to vanillin. Vanillin I is widely used in the food and cosmetic industries, and therefore it is a very important component for the production of medicines, herbicides and detergents.
In addition, the demand for its use is growing, in 2018 it rose to 37 thousand tons. Vanilla is sold from the vanilla fruit and is not enough. Currently, about 85 percent of vanillin is produced industrially from chemicals obtained from fossil fuels. The new path must not only be very attractive and efficient, but also be very beneficial in improving the environment.
This is the first example of using a biological system to recycle plastic waste into a valuable industrial chemical, said Joanna Sadlerof of the University of Edinburgh, and this has very exciting implications for farms.
Her words were also recognized by her assistant Stephen Wallace. Our work questions the perception of plastic as a problematic waste and instead shows its use as a new source from which to produce high-value products, he said. Watchman.
He also added that scientists need to adjust the way they use bacteria. However, the case was acknowledged and well executed. It’s a really interesting use of the microbile always to improve sustainability. Using microbes to turn waste plastic, which is harmful to the environment, into an important commodity, said Ellis Crawford of the Krlovsk Chemical Society, is a beautiful piece of green chemistry.
