Observation, Isolation and Characterization of Microalgal Red Tide Agent Dinoflagellates Prorocentrum sp
Abstract: Dinophyte species
inhabit from polar, temperate to tropical waters, but tend to be more abundant
in tropical or warm waters. The Dinophytes is suspected as one of the genera
causing red tide in the sea with their yellow-redish colour that make the sea
glows in the night because of their bioluminescence activity. In this work, the
Dinophyte was isolated from offshore, and water sample collected in Iwate
Prefecture, Japan. Purposes of the studies were for understanding the taxonomic
features in particular of the dinophytes that usually occur in blooming areas.
The species has specific characters, such as oval shape ( 20-30 μm long and
1-20 μm wide), yellow chloroplast, large nucleus, possesses two different
flagellas which one of them is specific called transfer flagellum, no middle
furrow and beautiful ornament cell covering (theca) with spine. Based on the partial
sequencing of the 18 S rDNA, the Dinophyte is precisely same as the reference
strain Prorocentrum MBIC11147 (100%), which was determined as Prorocentrum sp.
In the future, this study could be uses as model of sequel behavior of the
microalgal red tide.
