Duckweed, an aquatic plant, uptakes nitrogen and phosphorous from wastewater, and it is also a biomass feedstock for livestock feed and biofuel production. Professor Morikawa and his colleagues discovered bacteria that promote the growth of duckweed and are working to
develop plant growth-promoting technology for application to hydroponic vegetable and crop culturing. The research is garnering high expectations for various purposes, including wastewater treatment at food factories, yield increases at “plant factories,” energy conservation,
Duckweed grown with symbiotic bacteria (right) grows more than twice as fast as duckweed grown without such bacteria (left).
