Ethanol Addition During Euglena Cultivation Reveals Enhanced Productivity of Biomass and Valuable Substances, as well as Improved Cell Recovery Efficiency.

Euglena cultivation with the addition of ethanol was found to contribute to increased productivity of biomass and valuable substances, as well as improved cell recovery efficiency, according to a joint study by Euglena Co., Meiji University, and the Microalgae Production Control Technology Laboratory at the RIKEN institute. The research results were published in the international journal “Applied Microbiology and Biotechnology” on March 21, 2023. ■The key points of the study are as follows Euglena has been considered for industrial applications due to its ability to produce various valuable substances. However, the

A mixed feed containing the microalgae Euglena and a type of seaweed known as “Asparagopsis taxiformis” has been found to reduce methane emissions from ruminant livestock.

Euglena Co., Ltd. has confirmed through research conducted in collaboration with Professor Takehiro Nishida from the Department of Life and Food Science at the Hokkaido University of the National University Corporation Hokkaido University of Veterinary Medicine that a mixed feed containing the microalgae Euglena and a type of seaweed known as “Asparagopsis taxiformis”※1 can reduce methane※3 emissions from ruminant livestock※2 without compromising their health. This research has been published in the academic journal “animals”※4. ※1 Asparagopsis taxiformis: A type of red seaweed known as Kagike-nori in Japanese.※2 Ruminant livestock: Domesticated animals l

Painting with Genes: Creating Colorful Euglena Seeds through Genome Editing

We are exploring how genome editing can unlock new ways to design life at the cellular level. One of our most fascinating projects has been engineering Euglena gracilis to produce seeds in a variety of striking colors. Among them, the pink-hued variants have become a personal favorite—tiny living canvases that showcase both scientific progress and the beauty of biology. This work builds on our recent research into carotenoids, a class of natural pigments that play essential roles in photosynthesis, protection against light stress, and cellular signaling. Earlier this year, we published a paper in Plant Physiology
