core tip: pet is a plastic commonly used in food packaging, with an annual global output of about 45million tons. Pet has become an important source of white pollution because it is extremely difficult to degrade. 70 years after the emergence of pet, scientists found the first bacteria that can degrade this plastic at room temperature in nature, and isolated two new hydrolytic enzymes petase and mhetase
[China Packaging News] pet is a plastic commonly used in food packaging, with an annual global output of about 45million tons. It is worth noting that pet has become an important source of white pollution because it is extremely difficult to degrade. 70 years after the emergence of pet, scientists found the first bacteria that can degrade this plastic at room temperature in nature, and isolated two new hydrolytic enzymes petase and mhetase
recently, the team led by researcher guoruiting of Tianjin Institute of industrial biotechnology, Chinese Academy of Sciences, used X-ray high-speed rail "the second spring" to be expected, and the crystal construction technology to analyze pet 10000 liters has also made suggestions and progress in packaging methods, product design and other aspects. The high-resolution structure of ase. At the same time, the team obtained the complex structure of petase and its substrate analogues for the first time, which is of great significance to understand how pet hydrolases recognize substrates. The relevant research was published in the international academic journal Nature communications
