Scenedesmus acutus (276--3a) und Chlorellafusca (211--8b) INGRID ROLLE, ROTRAUT PAYER und CARL J. SO~D~R Kohlenstoffbiologische Forschungsstation e.V., Dortmund Eingegangen am 4. Januar 1971 Amines in Unicellular Green Algae 1. Spermidine Content ofScenedesmus acutus (276--3a) and Chlorella/usca (211 --8b)
Summary. From the 10 to 11 major amines which could be distinguished in the unicellular green algae Chlorella ]usca and Scenedesmus acutus, by thin-layer chromatography, the following compounds were identified: Aethanolamine, methylamine, dimethylamine, putrescine and spermidine. Cadaverine and spermine were lacking. The spermidine content of both of the algae was quantitatively determined, and its dependence on age, temperature, light intensity and source of nitrogen was tested. The average spermidine content in algae cultivated at 30~ was 1.9mg/g dry weight (minimum 0.29 rag/g, maximum 2.24 rag/g). The spermidine content decreased with decreasing temperature as well as with increasing age. With KNO 8 or (NH4)2SO 4 as the source of nitrogen, the spermidine content was significantly higher as compared to algae grown in urea. Light intensity had no effect on the spermidine content.
