| strain dependent production of ciguatoxin precursors (gambiertoxins) by gambierdiscus toxicus (dinophyceae) in culture. | thirteen strains of gambierdiscus toxicus isolated from queensland (australia), hawaii, french polynesia and the virgin islands were mass cultured and extracted for ciguatoxin. a biodetrital sample containing wild g. toxicus collected from the republic of kiribati was also extracted for ciguatoxin. ciguatoxin, as characterized from moray eels, was not detected in any of the strains examined. two queensland strains and the wild g. toxicus produced putative ciguatoxin precursors named gambiertoxin ... | 1991 | 1926177 |
