From October 17 – 19, the first birthday of the journal was celebrated with a conference to which over 100 scientists attended.

Signing ceremony of the Qingdao Synthetic Biology Technology Innovation Strategic Alliance

T the conference theme was “Innovation of green and low-carbon technology, empowering carbon peak and carbon neutrality”, focusing on carbon resources, low-carbon conversion technology, multi-energy integration and utilization and other fields for in-depth discussions. The conference invited more than 100 experts, scholars, and business people to attend the conference.

As the chairman of this conference, QIBEBT director and Green Carbon editor-in-chief Lv Xuefeng said that this conference aims to build a high-level exchange platform for scientific research in the field of green and low-carbon research across the country. Breakthroughs will be sought in perovskite photovoltaics, solid-state lithium batteries, biosynthesis of energetic materials, green bio-jet fuel, new generation of bio-based green plasticizers, and iron-branched butyl-pentane rubber. In order to further expand China’s academic influence in the field of green and low-carbon science and technology, the international academic journal Green Carbon aims to promote scientific and technological innovation in the field of sustainable development and provide a high-quality and open academic exchange platform for global researchers in the field of green and low-carbon.

At the meeting, the “Qingdao Synthetic Biology Technology Innovation Strategic Alliance” jointly established by the Qingdao Institute of Energy and relevant enterprises, universities and research institutes was formally established. Qingdao Wanyuan Environmental Technology Co., Ltd., Shandong Jinzhirui New Materials Development Co., Ltd., Shandong Environmental Protection Development Group Co., Ltd., Qingdao Zhongchuanghuike Biotechnology Co., Ltd., Qingdao Zhongke Green Carbon Technology Co., Ltd., Shandong Hengxin Group Co., Ltd., Qingdao Zhongke Yuanben New Energy Co., Ltd., and China Hydrogen Energy Company (Energy Cube (Qingdao) Data Technology Co., Ltd.) signed contracts with the Institute respectively.

The conference also held a special event for the first anniversary of the publication of the international journal Green Carbon. Jiang Lei and Lv Xuefeng presented the “Excellent Editorial Board Award” to Rolf Schmid, Tang Yong, Chen Xuesi and Lv Xuefeng presented the “Excellent Young Editorial Board Award” to 24 young editors, and Rolf Schmid and Lv Xuefeng jointly unveiled the Green Carbon Overseas (Germany) Office.

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.
