Abstract
Thylakoid membranes were isolated from seven plant species. The isolated thylakoids were immobilized onto carbon paper electrodes and the photocurrent was measured. Spinach thylakoids showed the largest photocurrent, 80 ± 10 μA per mg protein and 430 ± 60 μA per mg chlorophyll. The electrodes were also tested in a bio-solar cell configuration. Open circuit voltages were the same regardless of the thylakoid source, and spinach thylakoid bio-solar cells had the largest currents. Exposure of the electrodes to diuron, a commonly used herbicide, showed that sensitivity varied by thylakoid source, with spinach having the highest sensitivity and green chard and beet greens having the lowest.
