- 論文の詳細を見る
The nature of the light-induced absorbance change of carotenoid, spheroidene, was investigated with the chromatophores of Rhodopseudomonas spheroides. The experimental results indicate that the change does not represent an oxidation-reduction reaction of the carotenoid, but is caused by a change in the state of the chromatophores dosely related to the high energy state of the photophosphorylation. Since the change almost vanishes at liquid nitrogen temperature, it probably does not represent a primary photochemical reaction in the chromatophores. The values of the quantum yield for the change of carotenoid were above unity ; 2.5 on an average.
