Towards chemical characterisation of lytic compound(s) produced by Alexandrium spp

These effects include immobilization, total cell lysis and/or cyst formation in the target species. High cell concentrations of Alexandrium are also known to cause gill damage associated with mass fish mortalities. There is ample evidence that these deleterious effects are not due to known phycotoxins, such as PSP toxins and spirolides, produced among various Alexandrium strains. Chemical structures of the lytic compound(s) are unknown and there is little information on their basic physical-chemical properties and mode of action. Here we present preliminary results towards chemical characterization of lytic compound(s) excreted by Alexandrium tamarense. Stability under various physical and chemical conditions was tested to further define the nature of the compound(s). Bioactivity was stable at 500 kD).
