RIKEN Baton Zone Program Microalgae Resource Upcycling Research Laboratory
Team Leader: Suzuki Kengo (D.Agr.)
Deputy Team Leader: Keiichi Mochida (Ph.D.)
Research Summary
The team is based on the former team, Microalgae Production Control Technology Research Team. In the former team, we established the world's first genome-editing technology for Euglena. Furthermore, we produced a large number of genome-edited strains by utilizing the established technology. We have also utilized those strains for genetics of Euglena and demonstrated the potential of the technology for use in breeding. The new team will focus in particular on adding value to the extraction residue when microalgae are used to produce lipids and sugars, and aim to further apply the above technologies in practice.
