Culture of Dinoflagellate. The isolate of toxicus (SIU 350) used in this study was obtained from the South Sound of Virgin Gorda, British Virgin Islands. The species was brought into unialgal culture and maintained in enriched sea water ( ) under continuous light (3200 lux cool white fluorescent) at 27.0° C.

Only one naturally occurring azide has been reported to date. 6-Azidotetrazolo[5,l-u]phthalazine (6) was isolated, by chloroform extraction and subsequent chromatographic purification, from unialgal cultures of Gymnodinium breve (Ptychodiscus brevis), a dinoflagellate responsible for the production of toxic red tides along the Gulf Coast of Florida [16]. The structure of this extraordinary secondary metabolite was determined by... 

Phytoplankton Cultures. A viable unialgal culture of the diatom Synedra sp. was split into 2 aliquotes. The first portion C VIABLE") was extracted immediately and analyzed. The second part ("DEAD") was purged with nitrogen, sealed and stored in the dark at room temperature (20-22 C) for 2 months before analysis. 

Use of axenic cultures is attractive in view of the high degree of reproducibility, and avoids potentially serious problems due to the possible occurrence of bacterial transformation of the toxicant during tests with unialgal cultures containing bacteria.
