Production of electricity from photosynthetic microorganisms

Building on previous research that discovered cyanobacteria (bacteria capable of oxygen-producing photosynthesis) produce small amounts of extracellular electric current, which increases under illumination, this project aims to explore the underlying mechanisms and potential applications for renewable energy production. The mechanisms of current export are not well understood, but the project aims to investigate this through studies with mutants, subcellular preparations, and genetically modified cells, utilizing advanced electrochemistry techniques.

The project has already demonstrated the practical application of cyanobacterial current by powering microprocessors used in the Internet of Things. This indicates the potential for real-world applications, particularly in isolated areas of low-income countries where small amounts of power can significantly impact. These systems could also serve as a sustainable alternative to batteries for devices requiring minimal power that cannot easily connect to a power supply.
