First report of the potentially toxic marine diatom Pseudo-nitzschia simulans (Bacillariophyceae) from the East Australian Current, Australia (2016)

One clonal strain of Pseudo-nitzschia simulans was isolated from the East Australian Current and characterized using light and transmission electron microscopy, and phylogenetic analyses based on regions of the internal transcribed spacer (ITS) and the D1D3 region of the large subunit (LSU) of the nuclear-encoded ribosomal deoxyribonucleic acid (rDNA), as well as examined for DA production as measured by liquid chromatographymass spectrometry. Although this strain was non-toxic under the defined growth conditions, the results unambiguously confirmed that this isolate is the potentially toxic species P. simulans the first report of this species from the Southern Hemisphere.
