Abstract

The occurrence of volatile nitrogen-containing compounds in the cyanobacterium Aphanizomenon flos-aquae has been studied. Twenty compounds belonging to four groups—amides of carboxylic and fatty acids, heterocyclic compounds and their derivatives, aromatics, and alkoxyamines and amides were identified by gas chromatography–mass spectrometry that used serially coupled capillary columns with different polarity of stationary phases. Distribution of bioactive non-toxic and toxic nitrogen-containing metabolites in cyanobacteria are discussed.
