| Popis: | 1. Quantum requirements for the light-induced bleaching of P 840 in the green photosynthetic bacterium Chloropseudomonas ethylicum were determined with actinic light mainly absorbed by chlorobium chlorophyll under a variety of conditions. The estimated values ranged from 12 to 8. 2. Light minus dark absorbance difference spectra of Cps. ethylicum suspended in distilled water indicate the participation of two cytochromes. 3. Light-induced absorbance changes in the green spectral region of Cps. ethylicum suspended in distilled water suggest the reversible light-induced formation of a carotenoid-like pigment. This pigment may be related to carotenoid synthesis. |
