From May 15 to 23, 2026, professor Matthias Hess, a Hellman Fellow and renowned microbiologist from the University of California, Davis, revisited the Institute of Subtropical Ecology Agriculture for collaborative research and academic exchange. He was invited by Professor Tan Zhiliang, Secretary of the Party Committee of the Institute of Subtropical Agriculture and Ecology, Chinese Academy of Sciences.

Matthias Hess is currently affiliated with the Department of Animal Science, College of Agricultural and Environmental Sciences, University of California, Davis. He has long been engaged in research on ruminant micro-ecosystems and their environmental impacts. His research areas include Animal Health/Animal Microbiology, Climate Change/Carbon and Nitrogen Cycling, Natural Products.

On May 16, Matthias Hess delivered an academic report titled “Introduce the framework of global methane mitigation”. In his report, he detailed his team’s research progress on the microbial mechanisms by which the addition of red algae byproduct and Anaerobic Gram-positive bacterium Blautia pseudococcoides to the diet regulates methane emissions from the gastrointestinal tract of ruminants, the regulation of rumen microbial gene expression, and the pathways of rumen microbial hydrogen metabolism.

This collaborative exchange deepened the cooperation between the two parties in the field of ruminant microbiology research and laid an important foundation for future collaboration.
