聚焦γ-聚谷氨酸合成生物制造技术难题，江南大学徐国强@SynBioCon 2025

Core Viewpoint - The article discusses the upcoming SynBioCon 2025 conference, focusing on the research and industrial applications of poly-γ-glutamic acid (γ-PGA), a biopolymer with significant potential in various fields such as functional foods, cosmetics, biomedicine, and biomaterials [1][3]. Summary by Sections γ-PGA Characteristics and Applications - γ-PGA's physiological functions and application areas are highly dependent on the proportion of L-glutamic acid monomers and molecular weight, with low molecular weight γ-PGAs (Mw<500 kDa) suitable for drug delivery and tissue engineering, while high molecular weight γ-PGAs (Mw>1500 kDa) serve as thickeners or flocculants [2]. Industrial Biotechnology Challenges - The efficient biosynthesis of γ-PGA from scratch and the directed synthesis of γ-PGA with varying L-glutamic acid monomer ratios and molecular weights are critical industrial biotechnology challenges that need to be addressed [3]. SynBioCon 2025 Conference Details - The SynBioCon 2025 conference will be held from August 20-22 in Ningbo, Zhejiang, focusing on the intersection of AI and biological manufacturing, as well as advancements and opportunities in green chemicals, new materials, future foods, future agriculture, and cosmetic raw materials [7][8]. - The conference will feature a special session, the "Youth Forum on Biological Manufacturing," aimed at providing insights into scientific issues, solutions, results, scalability, and future directions in the research field [7][8]. Conference Agenda - The agenda includes registration, a closed-door seminar for industry leaders, project roadshows, and various forums covering topics such as green chemicals, new materials, and future foods and agriculture [8][10].
