Green autofluorescence in dinoflagellates, diatoms, and other microalgae and its implications for vital staining and morphological studies

Article Abstract:

The epifluorescence microscopic and quantitative spectrometric measurements of green autofluorescence (GAF) are described in a broad phylogenetic range of microalgae. The results have shown that GAF is a common feature of dinoflagellates, diatoms and other microalgae and it can be used for microscopic study of algal morphology and visualize dinoflagellate cysts in marine and estuarine sediments.

Characterization of nontoxic and toxin-producing strains of alexandrium minutum (dinophyceae) in Irish coastal waters

Article Abstract:

Study is conducted to generate clonal cultures of A. minutum isolated from diverse regions around the Irish coast and to compare them with respect to their morphology, toxin composition and genetic diversity. Results shows that the divergence in toxin profiles among the A. minutum strains isolated from Irish waters is not associated with differences in the LSU and ITS regions of rDNA.

Reevaluation of production of paralytic shellfish toxin by bacteria associated with dinoflagellates of the Portuguese coast

Article Abstract:

Research has been conducted on paralytic shellfish toxins produced by cyanobacterial and dinoflagellate species. The authors have investigated paralytic shellfish toxin production by the bacterial strains isolated from toxic dinoflagellates via the use of analytical and biological methods.
