BIBLIOGRAPHY TO CHAPTER 26 883 



However, the antibiotic activity of "chlorellin" is not affected by thiourea 

 and potassium iodide, which destroy labile peroxides. Spoehr and co- 

 workers noted considerable similarity between "chlorellin" and the first 

 antibiotic, discovered fifty years ago (but never chemically identified) — 

 the pyocyanase from Pseudomonas ruginosa. In both cases, the material 

 seemes to be a mixture of several unsaturated fatty acids. 



Further chemical study showed that the mixture obtained by photox- 

 idation of the fatty acids from Chlorella contained short-chain acids (about 

 Cii) separable by distillation, and showing a relatively strong antibacterial 

 activity. 



The studies of Pratt and Spoehr offer a promising approach to the 

 understanding of at least some of the phenomena in photosynthesis usually 

 attributed to not further identifiable "plasmatic" or "internal" factors.
