Japan actively develops biodegradable plastic technology

Japan began to research and develop this technology from the 1980s. At present, the annual output of biodegradable plastics is 1,000 tons, and it is expected to reach 5,000 tons in two years.
The Japanese Institute of Physics and Chemistry developed a bio-polyester manufacturing technology in 1987. In 1993, it isolated the microorganism Aeromonas Caviee from the soil. By supplying vegetable oil as a carbon source, another copolymerizable polyester is synthesized. The physical properties of these biopolyesters change due to changes in the composition of the copolymers, and they become polymer materials exhibiting various physical properties, such as hard crystalline or elastic plastics, which can be processed into tough silk and transparent soft films. Wait.
Japan has isolated more than 50 microorganisms (mainly bacteria) that can decompose high-molecular plastics from a variety of environments, and it has refined the hydrolytic enzymes of polyester from several of these microorganisms, and recently deciphered the amino acid arrangement of some of these enzymes. Physics and chemistry applied transgenic technology to implant the genes of Aeromonas Caviee polymerase into the generatotrophic bacterium Eutrophue of the polymerase polymerase to produce a transgenic microorganism. Using palm oil and olive oil as carbon source, it can efficiently produce 3-hydroxybutyrate. Bio-polyesters of acid and 3-hydroxyacetic acid co-polymers have been successfully developed using imitation vegetable oils or technetium to allow microbes to efficiently produce high-performance co-polymerized polyesters. Japan is applying genetically modified technology to study the technology of implanting polymerase genes into plants, and the technology of making bio-polyesters efficiently from plants using co2 and water, and making progress.
