中国深海生物样本保藏技术方案成国际标准

Core Viewpoint - The release of the international standard "ISO20309:2025 Biotechnology— Biobanking— Requirements for deep-sea biological material" marks a significant achievement for China, transitioning from "Chinese standards" to "global benchmarks" in deep-sea biological sample preservation technology [1][3]. Group 1 - The international standard was developed by BGI Group in collaboration with multiple institutions and was officially released on December 9 [1][3]. - The project team also published the national standard GB/T46753-2025 for deep-sea biological sample collection, processing, and preservation, which was approved on December 2 [3]. - The initiative began in December 2022 when the team applied for a project with the International Organization for Standardization (ISO) [3]. Group 2 - The collaboration involved institutions such as the Chinese Academy of Sciences, Shanghai Jiao Tong University, and the Yellow Sea Fisheries Research Institute [3]. - The standard addresses key technical challenges in the preservation of deep-sea biological samples, providing a unified scientific basis for standardized operations and management globally [3]. - BGI has been focusing on deep-sea research since 2018, aligning its platform and technological advantages with national deep-sea strategies, and has participated in significant oceanographic expeditions [3].
