The 2023 National Science and Technology Awards were announced in Beijing. From a total of 262 projects and candidates,15 achievements in Qingdao won the National Science and Technology Award

Qingdao hosted and completed 2 award-winning projects, participated in the completion of 13 award-winning projects – Including 1 special prize, 1 first prize, 11 second prizes.

5 of the award-winning Qingdao projects are in the maritime field, namely:

“Key Technology Equipment and Application of Deep Sea Image Detection”
Offshore Petroleum Engineering (Qingdao) Co., Ltd. participated in and completed the “‘Shenhai No. 1’ ultra-deepwater gas field development project key technology and application” project, which won the first prize of the National Science and Technology Progress Award
“Construction and Industrial Application of Precision Nutrition Technology System for Marine Cultured Fishes” led by the Ocean University of China and participated by the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences.
“Theoretical and Technological Innovation and Major Discovery of Deep Oil and Gas Exploration in Fault Zones” project, and the
“Key Technologies and Applications for Beach Protection and Restoration of Complex Coastal Environments” participated by Ocean University of China won the second prize of the National Science and Technology Progress Award.

In addition, Qingdao’s participation in award-winning projects has high “gold content” and broad influence. Among them, the “Fuxing High-Speed Train” project completed by CRRC Qingdao Sifang Rolling Stock Co., Ltd. and CRRC Qingdao Sifang Rolling Stock Research Institute Co., Ltd. won the special prize of the National Science and Technology Progress Award. The “Fuxing” high-speed train is a new generation of high-speed train independently developed by China and with complete intellectual property rights. With a maximum speed of 350 kilometers per hour, China has become the country with the fastest commercial operation of high-speed rail in the world. This record remains to this day. As of the beginning of this year, the “Fuxing” high-speed train has transported more than 2.2 billion passengers.

Enterprise innovation is the fundamental driving force and internal source of innovation. Among the Qingdao award-winners, 9 projects have enterprises taking the lead in completing and deeply participating in them. For example, the “Technological Innovation and Industrialization of Temperature and Humidity Oxygen Magnetic Multi-dimensional Precision Control of Household Preservation Appliances” project led by Haier Smart Home Co., Ltd. and participated by Qingdao Haier Refrigerator Co., Ltd. won the second prize of the National Science and Technology Progress Award; Tsingtao Brewery Co., Ltd. The project “Efficient Breeding and Optimization of Key Technologies and Applications of Food Biomanufacturing Industrial Strain”, as the main completion unit, won the second prize of the National Science and Technology Progress Award.

Trans-aconitic acid from Aspergillus terreus – a new biopesticide and bio-based plasticizer

Trans-aconitic acid TAA (CAS RN 4023-65-8) is an unsaturated tricarboxylic acid that occurs in various plants. Although it exhibits broad application potential in agriculture, food, biomaterials, and green chemistry, its practical use remains limited. This is primarily because the traditional production processes of plant extraction (from sugar cane)and chemical synthesis (complex and inefficient) cannot achieve large-scale production at a low cost.

Researchers around LU Xuefeng, director of the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) under the Chinese Academy of Sciences, have now established a cell factory for the production of TAA based on a genome-edited industrial strain of Aspergillus terreus. Several rounds of metabolic engineering resulted in strains which produced 57 g/L TAA in shake flask cultures. Scale-up to tank fermentations up to 120 kL – in cooperation with Shandong Lukang Pharmaceutical Co., Ltd.– then led to yields of 88 g/L after 100 hours. A simple recovery procedure combining membrane concentration and crystallization provided TAA crystals with a purity of 98.4%. Given its superior nematicidal properties, QIBEBT and Lukang Pharmaceutical are now in the process of registering TAA as a new nematicide biopesticide.

The QIBEBT team has further found that TAA esters (trans-Aconitates) can be used as plasticizers and could replace the ambiguous phthalates widely used in plastic products. Haier Blood Technology Co., a Qingdao-based company, plans to use TAA esters as plasticizers in its PVC-based blood bags and other products.

TAA ester’s wide temperature stability, from -46°C to 120°C, might also find applications in automotive cable materials as they exhibit excellent resistance to high-temperature volatilization and low-temperature brittle cracking.

In summary, biomanufacturing based on smart cells of A. terreus has provided a new material, TAA and TAA esters, which offer exciting application potentials as a biopesticide and a non-toxic bioplasticizer.

Ocean University of China in Qingdao publishes Blue Book on marine CO2 absorption

https://spc.jst.go.jp/news/250903/topic_2_03.html

A “China Blue Carbon 2025” Blue Book was released in Qingdao. The Blue Book project was led by the Marine Carbon Neutrality Center of the Ocean University of China, and had invited more than 70 experts and scholars from over 30 institutions in China and abroad to conduct joint special research.

The blue paper predicts that carbon dioxide absorption by China’s blue carbon ecosystems has been on the rise for over the past decade, reaching 500 million tons of carbon dioxide equivalent by 2035, at which point China will play a central role in global blue carbon contributions. By 2025, China’s total mangrove area will be approximately 303 square kilometers, with a total carbon storage of 6.03 million tons; seagrass beds will be approximately 265 square kilometers, with a total carbon storage of 2.3 million tons; and coastal salt marshes will be approximately 2,980 square kilometers, with a total carbon storage of 91.55 million tons.

The paper also notes that carbon absorption by shellfish and algae farming in China’s coastal waters has increased over the past 20 years. At the same time, China’s marine energy has also developed, with its offshore wind power capacity now number one in the world and its marine primary and secondary industries achieving “carbon minus” status.

According to the president of Ocean University of China, the university aims to achieve synergistic effects on the ecosystem, society, and economy by developing seagrass bed restoration technology, to building a blue carbon resource survey and calculation system, and even developing technologies to track and treat the sources of coastal pollutants.
