Photochemical energy conversion systems using immobilized chloroplasts
Immobilized chloropasts and Clostridium butyricum were employed for a photochemical energy conversion system. Spinach chloroplasts were immobilized in 2% agar gel. The optimum temperature of immobilized chloroplasts was 30 degrees Celcius. The maximum activity was obtained in the phosphate buffer solution (pH 8.0) containing 8 mu meters of ferredoxin under an N2 bubbling condition. Hydrogen was evolved under illumination by immobilized chloroplasts and C. butyricum. Hydrogen produced by this system was applied to a hydrogen-oxygen fuel cell. Photoinduced current was obtained from this photochemical energy conversion system. A photocurrent 0.4-1.5 mA was continuously obtained for 4h. The conversion ratio from hydrogen to current was 80-100%. (Refs. 12).
