In addition, scientists have also been looking for more efficient ways to degrade plastics, hoping to deal with the generated plastic waste faster. Another very important method to treat plastic pollution is bioremediation. Bioremediation refers to the use of natural organisms to remove or neutralize pollutants. Among them, the most environmentally friendly and most promising method for plastic pollution control is the use of microbial degradation methods. Microbial degradation of plastics refers to the chemical reaction process that catalyzes the cracking of polymer bonds into monomers through some unique enzymes in microorganisms, which is a chemical reaction process that accelerates the degradation of plastics. Since plastics usually take a long time to degrade, the enzymatic catalysis can greatly reduce the time that plastics stay in nature and reduce the damage of plastics to the ecological environment. And just recently, a team from the Institute of Oceanology, Chinese Academy of Sciences found a flora in the ocean that can effectively degrade two common plastics: PET (polyethylene terephthalate) and PE (Polyethylene) plastic. The research team also published this scientific achievement in the recent publication of JOURNAL OF HAZARDOUS MATERIALS. The results of this research are of great significance for the treatment of plastic waste. Because PET and PE plastics account for 46.5% of all plastic waste in the world, it can be said that finding a way to treat PET and PE plastics will find a way to treat nearly half of plastic pollution. PET plastic is one of the very common plastics. We can not only find it in beverage bottles, but also often see it in electrical products, automotive products, and daily life. PE (polyethylene) plastic is one of the five major synthetic resins. It is also the variety with the largest production capacity and the largest import volume among synthetic resins in China. It is often used to manufacture films, coatings and other products. What’s more troublesome is that both PET and PE compounds have many properties that are difficult to biodegrade, such as long hydrocarbon chains, high molecular weight, high tensile strength, low air permeability, and durability against physical and chemical degradation. For the degradation of PET plastic, scientists have previously discovered that cutinase, lipase, and esterase can effectively catalyze the degradation process of PET plastic. However, in current scientific research, there are relatively few discoveries about the degradation of PE plastics. Although people have found that PE plastics have great potential for degradation by co-cultivating PE plastics with specific microorganisms in the laboratory, At present, the known degradation methods of PE plastic by a single strain or a single enzyme are too low in efficiency to meet the needs of industrial applications. Therefore, in this study, the research team of the Institute of Oceanology of the Chinese Academy of Sciences targeted the degradation of microbial communities, that is, under the synergistic effect of a combination of multiple microbial species, the degradation efficiency of plastics is likely to be greatly improved. (Source: Internet) This discovery was led by Sun Chaomin, a researcher at the Institute of Oceanology, Chinese Academy of Sciences. Since 2016, this team has been analyzing and screening thousands of samples of marine plastic waste collected from the coastal waters of Qingdao. These samples contain several Hundreds of plastic wastes. After unremitting screening and analysis, they found that a marine bacterial community can effectively colonize and degrade polyethylene terephthalate (PET) and polyethylene (PE), and in an environment containing plastic waste, This bacterial community has better growth ability instead. Researchers speculate that this is because the energy required for the survival of this bacterial community is obtained by degrading PET plastic and PE plastic. Next, in order to specifically find out which bacteria in the bacterial community played a role in the degradation of PET plastic and PE plastic, the researchers quantitatively analyzed the composition and abundance of this bacterial community and found that there are Five kinds of bacteria have a stronger survival advantage in the culture medium of plastic waste. Then, through bacterial culture scientific researchers successfully obtained pure culture strains of the above five types of bacteria, and further investigation found that three of them have significantly stronger plastic degradation ability. In order to further study how these three strains can work together to exert a synergistic effect and how to most effectively degrade plastics, researchers will compound the three strains in different proportions and conduct a comparative analysis. In the end, this scientific research team successfully established a stable marine bacterial community that can effectively degrade PET and PE plastics. Researchers also continue to use liquid chromatography-mass spectrometry to prove the effective degradation of the established flora for the degradation of PET plastic and PE plastic. This research not only found the microbial populations that can degrade nearly half of the plastic waste in the world, but also gave important suggestions for the industrialization of plastic waste biodegradation from a biological and mechanical point of view, which is a path for the biodegradation of plastic waste. Important milestones. -End-

The under eye patch is advertised as a product to help get rid of the swelling on the skin. Some manufacturers even promise the patches can remove wrinkles. But there are some rules you should never forget to use eye patches effectively and without harming the skin. – Do not use your hands to remove the under-eye patch from the box. The women in the advertisements often use their fingers to apply the patch under their eyes. But if you put your finger in the container, there’s a good chance bacteria can get in. So it’s best to use a special tool to remove the patches. Some manufacturers put the tool in an under eye patch holder. – Don’t leave the patches on your face for too long. The manufacturer recommends spending only 15-20 minutes to apply the patches. And there is a reason for this. When the patches provide all the moisture they have, they begin to draw moisture out of the skin, leading to more wrinkles. Therefore, you should not leave the patch on your face for too long. – Do not store the stickers in the refrigerator. Some experts think it’s better to put the patch in the refrigerator before using it. And some people put them in the refrigerator all the time. Cold patches will reduce figs quickly but patches may be less effective if they are kept cold for a long time. Ideally, you should simply place the pack of patch in the refrigerator 20 minutes before using it. 2. Ice cream In the advertisements, women put a variety of creams on their faces. But even the best cream out there can turn your face into a greasy pancake if you take too much. Interestingly, in the advertisements, they spread the cream evenly over their face so that all skin areas have the same amount of cream. But this is not always the case. You need to find the driest areas of your face. Maybe some spots have more wrinkles and need more cream. On average, any skin type only needs a pea-sized maximum of cream for the entire face. Applying a little cream over the T-zone is the easiest part. 3. Clay mask Ads and even some manuals say that clay masks should be left on until they are completely dry and even begin to crack. But this is wrong – it will only harm the skin. Clay absorbs excess oil and removes dirt, but if you leave it on for too long, it absorbs moisture in the skin and makes it excessively dry. In addition, the dry clay will pull on the skin, which can cause new wrinkles. So, you should apply clay mask for 10 minutes and remove them before they dry again. 4. Paper Masks The reason why paper masks are so effective is because they adhere so tightly to the skin. It is better to spend more time removing all wrinkles and letting the mask touch all areas of the face than it is to apply and remove. Applying these masks will not cleanse the skin. If you do not wash your face with the gel, the active ingredients in the mask will not be able to penetrate the skin. Remember to carefully read the instructions for use! Some masks should not be used every day. Other masks can stay on skin longer than 15-20 minutes, and some need to be rinsed off after you remove the mask. 5. Exfoliate your skin Exfoliants have strong particles that damage the skin more than exfoliate the skin. To get rid of dead skin, it’s better to use products that contain acids. If you still like mechanical exfoliation, wear gloves and cleanse your skin. Another common misconception is that oily skin requires regular use of exfoliants. In fact, the more often it exfoliates, the greasy the skin is. So, do not exfoliate more than 2-3 times a week. If you use acidic products, apply sunscreen before going outside. Most sunscreens are advertised to be used on sunny days and when it’s cloudy. Remember to apply sunscreen right away, even if you are not using acidic beauty products to avoid chloasma and premature aging. 6. Other mistakes – Consuming too many beauty products in a row can be harmful to your health. Today, there are so many beauty products out there that we buy and use them all at the same time. But be aware that some ingredients should not be used together. In addition, when you use too many products at once, you can clog pores and decrease the protective function of your skin, even if all products are of high quality. – Scrubbing your face too hard can damage your skin. Cotton swabs and towels can stretch the skin if you rub it too much on your face. If you use a cotton swab to apply skin care products, make sure the cotton swab is wet. It just slides on the skin without stretching the skin. If you regularly use one motion to wash your face, chances are you haven’t washed the upper forehead, chin area, and ears. So, pay attention to those areas when washing your face.
