The photochemical activities of various species of unicellular algae (Anacystis nidulans, Chlorella pyrenoidosa, and Porphyridium cruentum) were studied following chemical fixation. Fixation with formaldehyde and glutaraldehyde yielded cells which retained their ability to perform photosystem I and photosystem II reactions. The photochemical efficiencies of some fixed algae are as great as those of unfixed spinach chloroplasts. Fixed algae containing accessory pigments appear to be useful models for further studies of the light reactions of photosynthesis.
研究了各种单细胞藻类(鱼腥藻、蛋白核小球藻和紫球藻)的光化学活性,这些藻类在化学固定后进行研究。用甲醛和戊二醛固定后,细胞保留了进行光合作用 I 和光合作用 II 反应的能力。一些固定藻类的光化学效率与未固定的菠菜叶绿体相当。含有辅助色素的固定藻类似乎是进一步研究光合作用光反应的有用模型。
