The degradation of plastic can be said to be a very difficult problem, you can find that in some documentaries, small animals accidentally eat plastic and then die on their own, and then the plastic is not degraded. Dealing with plastic waste is a very difficult problem, and plastic can also be a serious natural disaster. However, relevant experts have found that human saliva may be able to decompose plasticHuman saliva contains an enzyme that can decompose PET plastic, and PET plastic is actually our common polyester resin, which is a very common material in life.
This study has not been validly validated, so further research is needed. And like plastic waste, not only will cause great harm to the natural world, but also to human beings. If the temperature of plastic tableware exceeds 65 degrees, harmful substances will be released, and these harmful substances will also enter the human body with food, harming people's central nervous system, kidneys and liver.
In addition, this garbage can also affect rivers, lakes and oceans. It will also affect the growth of crops, lead to the loss of nutrients in the soil, and also cause the crops to be cysted during the planting process, unable to absorb water and nutrients normally. In addition, during the survey, it was found that nearly 276 species of marine organisms in the world died due to accidental ingestion of plastic.
The damage and pollution caused by plastic waste is very serious, and plastic is difficult to degrade. If it is buried underground, it is easy to cause damage to the land, so scientists have been studying how to quickly degrade plastic waste. If human saliva can really decompose plastic, then it can reduce a lot of plastic waste and reduce the harm to nature and human beings themselves.

The scientific basis lies in the fact that because humans often eat food packaged in ppt plastic, making saliva, why the microbes in the gut may have evolved to the point of digesting plastic, and the team found a special substance that can decompose this plastic in the search for genetic data control that humans drag on.

Studies have found that human saliva may be able to decompose plastics, a phenomenon that was found in a research institute in Thailand. When researchers studied human saliva, they found that there may be a special enzyme in it, which can decompose PET plastic. If it can really be copied and applied to life, it will be of great help to solve the problem of waste plastics.
However, this achievement only exists in the laboratory, and the special enzyme is only possible, and has not been determined, so further research is needed.
When exploring the natural world, human beings have never stopped exploring themselves, and plastic pollution is now very serious, which is regarded as a threat by many countries. And the substance in the plastic is PET, which is what we call polyester resin. It is extremely difficult to decompose this polyester resin, which often accumulates in the ground for more than 10 years, and can still be seen when excavating, and will not disappear completely.
If this enzyme can really be broken down from saliva, it will surely be able to solve people's major problems. The reason why it is said that it may exist is because when humans eat food, they will eat some PET plastic into their stomachs, but these plastics will be digested, so it is speculated that human saliva or digestive juices contain some microorganisms that can digest plastics.
Research is still ongoing, and hydrolase enzymes can only break down common PET plastics, so there is no way for varieties with high crystallinity. It can only be said that plastic is really very powerful, it is very convenient when it is used, but it will be useless after use, and people will not make complete use of plastic, and some plastic will always float into the ocean, and people have found plastic molecules in the lungs and blood of marine animals, which is more terrible.
The discovery of a study is from scratch, and it is believed that with the investment of funds and further analysis of personnel, it will definitely be able to obtain relatively large achievements from it, and find enzymes or microorganisms that can really decompose plastics.

Researchers believe that microbes in saliva, stomach or intestines may have evolved to digest plastic because humans eat PET-wrapped food. While searching a public metagenomic database containing human saliva samples, the team discovered a hydrolase enzyme capable of breaking down PET plastic, which they named MG8. In the experiment, the team found that the enzyme can not only easily decompose PET plastics, but also require only minor modifications, and the enzyme can also be efficiently combined with PET plastics to functionalize the surface of PET plastics, such as increasing the use of this plastic in medical devices.

In the face of growing plastic pollution, scientists around the world are actively looking for ways to deal with it. A few days ago, a research team from the Institute of Science in Thailand and Chulalongkorn University found that human saliva may contain an enzyme that can decompose PET plastic, commonly known as polyester resin, a common material in life. What is the scientific basis for the study that human saliva or decomposable plastics?
1. The content of human saliva
Saliva is a mixture of large and small salivary glands, and there are three pairs of large salivary glands in the human mouth, namely the parotid gland, the submandibular gland, and the sublingual gland. Saliva is colorless, odorless, and nearly neutral. About 99% of the water content in the saliva.
Organic matter is mainly mucin, as well as immunoglobulins, amino acids, urea, uric acid, salivary amylase, lysozyme bacteria and inorganic salts, and some heavy metals and rabies virus that enter the human body can also appear in saliva through salivary gland secretion.
2. Human saliva evolution
Because humans consume large amounts of food packaged in PET plastic, microbes in saliva, stomach and gut may have evolved to the point where they can digest plastic. Therefore, the researchers systematically explored the metagenomic data and identified a new PET hydrolase, Mg8, from the human saliva metagenome. It is the first PET hydrolase identified from the human metagenome, at different temperatures and salinity strips.
3. Plastic degradation
If plastic can really achieve effective biodegradation, it must be after the completion of more effective treatment of lignin cellulose, after all, the latter has a complete degradation fermentation mechanism, only needs to be more in line with human needs in engineering, if future scientists can carry out saliva degradation is also a good thing.
Postscript: Plastics are routine, studies have shown that many people in the human body will have microplastics that may enter the human body through various ways such as air, water or food, and may also enter the human body through specific toothpaste, lipstick and tattoo ink. Theoretically, plastic particles could be transported through the bloodstream to the organs, which is why the body can be purified.

Introduction: In the face of growing plastic pollution, scientists around the world are actively looking for ways to deal with it. Recently, research said that human saliva may be decomposable plastic, and this finding has a very important contribution to solving plastic pollution, alleviating garbage pollution and creating a greener environment for our world.
Studies have shown that the salivary enzyme can easily break down PET plastic, which means that Yuqibu reduces plastic pollution. Plastic pollution is already serious in increasingly industrialized cities, and scientists are actively looking for ways to solve it. The advent of this enzyme will be solved in the face of plastic pollution or Qingsui, and it is also a major breakthrough on the road to solving plastic pollution, providing a new idea and method for solving the plastic problem.
The study found that the salivary enzyme can decompose PE plastics, and it is more meaningful that it can alleviate the greenhouse effect, China's carbon dioxide emissions are the second largest in the world, and the use of a large number of plastics requires a large amount of oil and energy, and oil combustion will also release carbon dioxide to aggravate the greenhouse effect. When plastic is burned, it will also release a large amount of carbon dioxide and toxic substances, which is harmful to the human body and also increases environmental pollution. If this research can be successfully published, then the more important significance is to alleviate environmental problems, reduce energy combustion and carbon dioxide release, and be more conducive to alleviating the white pollution and greenhouse effect caused by some areas, and have far-reaching positive significance for environmental protection.
Industrially produced plastics cannot be degraded naturally. The human salivary enzyme in this study can decompose plastics, which can realize the redevelopment of plastics, and industrial development also has great positive significance. According to statistics, 3.5 million tons of plastics are difficult to utilize, and the environmental problems caused by this are becoming increasingly serious.
The human salivary enzyme in this study can not be promoted to the use of plastics, which can not only reduce pollution in the environment, but also be of great significance in industrial development and the use of resources.
