University of Turku

Research at the University of Turku focuses on uncovering the molecular mechanisms of photosynthesis and applying this knowledge to develop bio-based strategies for efficient and sustainable bioproduction.

The Bioenergetics, Biochemistry, and Molecular Biology of Photosynthesis teams investigate processes at the molecular level. Using state-of-the-art commercial instruments alongside custom-built setups, they study all components of the photosynthetic electron transport chain as well as whole-cell function. Supported by an extensive mutant library and a diverse collection of specific antibodies, these teams conduct precise and targeted analyses of photosynthetic regulation and its connections to carbon and nitrogen metabolism.

The Photosynthetic Biotechnologies teams integrate synthetic biology, metabolic engineering, and bioprocess design to harness photosynthetic organisms for the production of fuels, chemicals, materials, food and feed. Their work enables the development of efficient and robust photosynthetic platforms, ranging from engineered cell factories to engineered living materials, supporting sustainable and continuous biomanufacturing.

The Photosynthetic Biomass-Based Bioproduction teams develop scalable microalgae cultivation processes that utilize industrial and agricultural effluents as nutrient sources. The AlgaTech facility, equipped with a range of photobioreactors (up to 1000 L) and downstream processing facilities, enables the handling of large-scale processes. The resulting biomass is converted into high-value products such as agrichemicals. Digital-twin modelling supports process optimization, scale-up, and performance prediction, facilitating sustainable large-scale production.
