Abstract
To establish a toxic microalgal culture
collection in Taiwan to support further
studies on red tide and harmful algal toxins.
Among 91 clones of different species, there
are toxic and nontoxic strains of the same
species. Ten microcystins have been isolated
from field collection of blooming population
of Microcystis aeruginosa and strain MTN-2
of the same species. Three of the toxins
are known to be new in literature. Among
12 Alexandrium minutum isolates there were
9 found to be toxic, and their toxin profiles
were different. One of the strain, AmTK6a
was known as the most toxic one ever
reported. It was also found toxic cells of A.
minutum and the purified toxin showed
toxicity to milkfish larvae by damaging fish
gills and thus causing a high demand and
consumption of oxygen in fish. From one
Prorocentrum lima isolate, okadaic acid, its
diol esters, and DTX-1 were isolated. One
of the diol ester of OA was known as new
compound. Spiroprorocentrimine, a new
compound was isolated and crystalized from
the extract of one unknown Prorocentrum
species, in addition to prorocentrolide and
hydroxyprorocentrolide.
