Tohoku University Technology: Improving Plant Saccharification: T24-049
Enabling the use of non-edible crop parts as an energy source
Biorefineries use biomass as a feedstock for chemicals and as an energy source, helping to reduce greenhouse gas emissions. However, the structural resistance of cellulosic biomass to degradation makes saccharification—a prerequisite for chemical production and energy conversion—challenging. Associate Professor Ito and colleagues at Tohoku University’s Graduate School of Agricultural Science have developed a method to improve saccharification by introducing a gene encoding a cytokinin biosynthesis enzyme into plants of the grass family. Cytokinins suppress plant senescence. The method uses intragenesis; no foreign DNA remains in the plant genome at the final breeding stage. The source therefore states that the method is not subject to restrictions under Japan’s Cartagena Act.

The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of April 1, 2026): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University - Asahikawa Medical University
