Make degradable plastics with microorganisms
maybe in the near future, whether it's handbags or plastic bags containing fruits and vegetables, you can safely throw them into the garbage can without deliberately classifying them or worrying about their pollution to the environment, because these handbags and plastic bags are made of a new generation of biodegradable plastics recently developed by scientists
biodegradable plastics use microorganisms as energy storage bodies to store plant, animal fat or glycogen. This biodegradable plastic produced by microorganisms is actually a polyester compound. Microbiologists at the University of Munster in Germany said that at present, only a few microorganisms in nature cannot produce polyester, and the vast majority of microorganisms can be used by humans. Microorganisms that can produce polyester and print 40000 green printing electronic tickets of nano materials for the national science and technology week are everywhere. They live in the soil and are adsorbed on the roots of spherical plants, sewage treatment tanks and the sea. They are like "micro plastic processing plants"
the premise for microorganisms to produce polyester compounds is to provide them with enough organic substances. They first eat organic matter and turn it into micro spheres, which are then stored in the body. Researchers take out micro spheres from these microorganisms and dissolve them with solvents or enzymes to obtain "bioplastics". The basic substance of this bioplastics is natural fatty acids
generally, the cost of polymers produced by bioreactor is too high to be used to produce daily packaging materials such as yogurt boxes and cheese bags. Germany has used ordinary methods to develop biodegradable cosmetic bottles, but users have not been found because of the high cost. Now, the production of cheap biodegradable plastics by microorganisms has been technically successful, and the most urgent problem is the yield
the method of obtaining natural fatty acids with this microorganism can not only be used to produce plastic bags, but also produce biological agents with good compatibility, especially fatty acid polymers. Because this natural fatty acid can be slowly released in the human body, the remaining part is only fatty acid, which will not produce side effects. In terms of its physical characteristics of being fixed on the horizontal test bench smoothly, it can be used as the main processing machine. The recycled plastic granulator will have a large customer base comparable to synthetic materials. Scientists have experimented with this material to make heart valve stents. They believe that it can also be used to make bone nails and safety drugs in the future. However, so far, the clinical application of this biopolyester has not been found
microorganisms are widely used. Scientists believe that these tiny organisms can be used to produce various polymeric molecules, which may provide people with basic substances that are not available in the natural biological environment. In short, the market demand for this process has also further increased, and the production of biodegradable plastics has found a bright way for mankind to solve the problem of global white pollution
