Overview of the Research Project

Establish a holobiont resource research center to study combination of duckweed and coexisting microorganisms
Contribute to the construction of a sustainable society by utilizing plants in the Lemnaceae family (duckweeds), which have high resource value and can grow in contaminated water where there is a high concentration of CO2. Specifically, (1) create a biobank of complex organisms consisting of duckweed and coexisting microbes, (2) understand and enhance microbial symbiosis that accelerates the growth rate of duckweed, (3) develop low-carbon water treatment technologies and duckweed production technologies, (4) manufacture biofuels, bioplastics, and livestock feeds, and (5) improve edible duckweed productivity and develop highly functional foods.

Develop greenhouse gas reduction technologies and valuable resources ranging from duckweed foods to biofuel
Contribute to the Bio-Circular-Green (BCG) economic model being promoted by the Thai government and to carbon offsetting by simultaneously addressing everything from development of duckweed-based bioresources to the creation of new industries.
