Achieve N₂O reduction of 40% or more by N₂O-removing rhizobia by maximizing the ability of N₂O-removing rhizobia through "symbiosis optimization" based on the identification and functional clarification of symbiosis-related factors of both plants and rhizobia. Accelerate social implementation of N₂O reduction technology by improving soybean symbiosis ability through co-inoculation of growth-promoting bacteria and N₂O-removing rhizobia.
 

Isolate N₂O reducing microbes (including rhizobia) from soils collected from across Japan, evaluate their N₂O reduction potential, and use them as candidate materials for microbial materials. At the same time, we will develop a viewer to facilitate the utilization of various data.
