Recently, the reporter learned from the School of Life Sciences of Peking University that the State Key Laboratory of Protein Engineering has successfully developed transgenic tobacco and transgenic cyanobacteria. The two transgenic plants can be used for bio-technical treatment of heavy metal contamination in soil and water. According to reports, genetically modified tobacco and genetically modified cyanobacteria can be used to adsorb and eliminate the pollution of heavy metals such as cadmium, mercury, lead, and nickel in soils and waters, in particular, it can eliminate the pollution of various export products such as rice, ginseng, Chinese herbal medicine, and tea. It meets export standards. At the same time, it can also be used to treat urban industrial wastewater, mining wastewater, and electroplating wastewater. It is reported that this scientific research achievement has already completed the experimental stage work and is expected to be popularized and applied as soon as possible. According to reports, this scientific research achievement has become the national 863 project and the Ministry of Science and Technology "Ninth Five-Year Plan" key research projects.
