Abstract

The maximum quantum yield of oxygen evolution in deuterated chlorella is found to be 0.075, while normal chlorella showed, in parallel experiments, a value of 0.10. Deuterated Chlorella vulgaris showed a decline in the quantum yield of oxygen evolution ("red drop") beginning at 680 millimicrons and a clear Emerson enhancement effect qualitatively similar to that obtained in normal chlorella cells. However, the ratio of quantumn yield at 680 to that at 710 millimicrons was about 1.5 times higher in normal than in deuterated chlorella cells. Action spectra of the Emerson enhancement effect in deuterated chlorella also are qualitatively similar to those of normal cells.

摘要

发现在重水培养的小球藻中，氧气释放的最大量子产率为0.075，而在平行实验中，正常小球藻的该值为0.10。重水培养的普通小球藻从680毫微米处开始，氧气释放的量子产率出现下降（“红降”），并且具有与正常小球藻细胞中获得的定性相似的明显的爱默生增强效应。然而，在正常小球藻细胞中，680毫微米处的量子产率与710毫微米处的量子产率之比比在重水培养的小球藻细胞中约高1.5倍。重水培养的小球藻中爱默生增强效应的作用光谱在定性上也与正常细胞的相似。
