Although several species of the Synurophyceae have been associated with taste and odor problems in potable water supplies, electron microscopic-based field studies linked problematic blooms only to Synura petersenii Korshikov.
Eventually, the organic compound trans-2, cis-6-nonadienal was implicated to cause the associated « cucumber-like » odors.
The objective of this study was to survey unialgal cultures of various Synurophycean species for the occurrence of trans-2, cis-6-nonadienal.
The compound was detected throughout a 24-day growth assay with a S. petersenii isolate, but was not detected in an identical assay with Synura sphagnicola (Korshikov) Korshikov.
