报告人简介：林赛·怀特教授
怀特教授拥有奥克兰大学博士学位，其研究生涯主要聚焦于海洋生物学、藻类学和水产养殖领域，尤其在海藻的增值应用和生物技术开发方面具有深厚造诣。他现任奥克兰理工大学（AUT）藻类学与渔业学教授，曾担任多个领导职务，包括学院院长和研究副院长。他还担任蓝经济合作研究中心（CRC）海鲜与海洋产品研究计划科学执行委员会成员。其研究成果获得超过1650万新西兰元资助，重点推进研究成果的商业化应用。
报告内容简介：
海洋生态系统演化出独特的微生物共生关系，能够实现惊人的生化转化。在食藻鱼类体内，后肠细菌能分解复杂藻类多糖，而这类物质现有工业酶无法处理。这些共生菌是关键所在，能从海藻碳水化合物（如岩藻多糖、褐藻酸等）中精准培育出具有特定生物活性和功能特性的定制寡糖。本报告深入探讨了这些微生物关系的生态学与进化基础，分析它们在开发海藻衍生产品新技术中的潜在价值，并指出这些发现将如何推动可持续水产养殖和蓝色生物经济领域的发展机遇。

Marine Microbial Symbioses: Unlocking New Biotechnologies for Tailored Seaweed Polysaccharides
Marine ecosystems have evolved unique microbial partnerships that enable remarkable biochemical transformations. In seaweed-eating fishes, hindgut bacteria break down complex algal polysaccharides that no current industrial enzyme can process. These symbionts hold the key to creating bespoke oligosaccharides from seaweed carbohydrates—fucoidans, alginates, and others—with precisely tuned bioactive and functional properties.
This presentation explores the ecological and evolutionary basis of these microbial relationships, their potential role in developing new biotechnologies for seaweed-derived products, and how such discoveries could transform sustainable aquaculture and blue bioeconomy opportunities.
Professor W. Lindsey White
With a PhD from the University of Auckland, Professor White’s research career has primarily focused on marine biology, phycology, and aquaculture with strong expertise in value-added and biotechnology uses of seaweeds.
He currently serves as a Professor of Phycology and Fisheries at Auckland University of Technology (AUT), where he has held several leadership positions, including Head of School and Associate Dean (Research). He sits on the Science Executive on the Seafood and Marine Products Research Programme in the Blue Economy Cooperative Research Centre (CRC). And his research has attracted over NZ$16.5 million in funding, with a strong focus on commercialising research outputs.
