Recently, the press conference of "Next Generation Industrial Biotechnology" and signing ceremony of Tsinghua University Life Science Academy and Yanzhou District Government were held in Shengning International Convention Center in Jining.
The platform of "Next Generation Industrial Biotechnology" was initiated by Professor Chen Guoqiang, a professor at Tsinghua University's School of Life Sciences and "Cheung Kong Scholar". To speed up the transformation of this technology, Parkson Biology and Tsinghua University established Shandong Parkson Biotechnology Co., Ltd. Research and development of bio-grade new materials (PHA) project, has completed pilot pilot industrialization, to achieve a non-sterile open low-cost continuous fermentation PHA production capacity, the transformation and upgrading of China's bio-manufacturing industry played a historic role in promoting.
The project uses the world's largest plastic bioreactor, high technology, environmental protection, greatly ahead of the international peer level.In order to fully docking the scientific research resources of Tsinghua University, Yanzhou District, promote industrial upgrading, Yanzhou District Government and Tsinghua University Institute of Life Sciences (Center for Synthesis and Systems Biology) signed a strategic cooperation agreement for the industry's old and new kinetic energy conversion provides an intellectual support.
Also present at the event were experts from universities such as Tsinghua University, Shanghai Jiaotong University, East China University of Science and Technology, Jiangnan University and Shandong University, as well as Qu Yaoyu, deputy district governor of Yanzhou District Committee and director of the District Office, and deputy secretary of Yanzhou Industrial Park Director Gong standard and so on.
'The next generation of industrial biotechnology' The industrial biology based on extreme microbial biosynthesis can overcome the shortcomings of existing biological manufacturing, promote the overall upgrading of biological manufacturing in our country and solve the ecological, resource and crisis of sustainable development. The project has been successfully piloted in Yanzhou of Jining, Shandong Province, with a 5-tonne pilot scale and a 1,000-ton production facility will be set up next year. In the second half of next year, 50,000 tons of existing materials will be produced using existing idle equipment and will be continued after the year Layout in the Northeast.
The project has three major bright spots: First, to achieve high-efficiency open-end continuous fermentation without sterilization, reducing energy consumption and complex operation of sterilization, greatly reducing labor costs; the second is to cultivate halophilic microorganisms need high concentrations of salt substrate culture It can use high-salt wastewater to replace freshwater resources and greatly save water resources. Third, bioreactors use materials such as plastics or ceramics without the need of high-temperature and high-pressure stainless steel materials, which greatly reduces the production cost.
In the early stage of research and development, the production of polyhydroxyalkanoate (PHA) strains was verified by a pilot production of a 7-liter fermenter. Afterwards, the industrialization technical team successfully completed the pilot-scale test at the Parkson Research and Development Center in Shandong Province. The pilot-scale production combined with the open and non- Of the fermentation process and downstream after the extraction process, the successful realization of a continuous batch of PHA powder stable production, reducing the total cost of 50%.
It is understood that, PHA as a high-performance bio-based biodegradable materials, according to different application requirements, manufacturing into pellets for downstream processing of the terminal product.At present, PHA pellets have been applied to biodegradable plastic sheet, a total of wood flour Mixed with pure PHA tableware, color 3D printing silk, electrospun fibers, shopping bags and other end products.
