an artificial photosynthesis system in development at the University of Toronto.
As both an «electrograph» (meaning it can undergo direct electron transfers from an electrode), and an «acetogen» (meaning it can direct nearly 90 - percent of its photosynthetic products towards acetic acid), M. thermoacetica serves as the ideal model organism for demonstrating the capabilities of this hybrid
artificial photosynthesis system.
