The toxigenic diatom Pseudo‐nitzschia cuspidata, isolated from the U.S. Pacific Northwest, was examined in unialgal batch cultures to evaluate domoic acid (DA) toxicity and growth as a function of light, N substrate, and growth phase. Experiments conducted at saturating (120 μmol photons · m−2 · s−1) and subsaturating (40 μmol photons · m−2 · s−1) photosynthetic photon flux density (PPFD), demonstrate that P. cuspidata grows significantly faster at the higher PPFD on all three N substrates… 

Effects of Organic and Inorganic Nitrogen on the Growth and Production of Domoic Acid by Pseudo-nitzschia multiseries and P. australis (Bacillariophyceae) in Culture

This study shows that Pseudo-nitzschia can readily utilize organic nitrogen in the form of amino acids, and confirms that both inorganic and organic nitrogen affect growth and DA production.

Emerging harmful algal blooms caused by distinct seasonal assemblages of the toxic diatom Pseudo-nitzschia in Narragansett Bay, RI, USA

Recurring Pseudo-nitzschia assemblages were driven by seasonal temperature changes and DA correlated with low dissolved inorganic nitrogen, likely caused by resident assemblage dependent on nutrient status as well as the episodic introductions of species that may be a result of oceanographic and climactic shifts.

The effect of Fe and Cu on growth and domoic acid production by Pseudo-nitzschia multiseries and Pseudo‐nitzschia australis

DA production during exponential growth of these two toxigenic Pseudo-nitzschia species is directly induced by Fe-deficient or Cu stress conditions and that 95% of this DA is actively released into the medium.

DOMOIC ACID PRODUCTION BY THE DIATOM PSEUDO·NITZSCHIA MULTISERIES AS A FUNCTION OF DIVISION RATE IN SILICATE-LIMITED CHEMOSTAT CULTURE

  • Biology
The results support the conclusion that DA is a secondary metabolite produced during conditions of stress due to silicate limitation, and show that P. multiseries is also capable of producing DA while growing in silicate-limited chemostat cultures.

Controls on Domoic Acid Production by the Diatom Nitzschia pungens f. multiseries in Culture: Nutrients and Irradïance

Nitzschia pungens f. multiseries (clone NPARL) was grown in nonaxenic batch culture under a range of growth conditions. Domoic acid (DA) was not detected during exponential growth, but production

Effects of Ammonium and Nitrate on Growth and Domoic Acid Production by Nitzschia pungens in Batch Culture

Four clones of Nitzschia pungens f. multiseries (toxin-producing form) and two of N. pungens f. pungens (nontoxic) were grown in batch culture at initial nitrogen concentrations of 55, 110, 220, 440,

CHANGES IN DOMOIC ACID PRODUCTION AND CELLULAR CHEMICAL COMPOSITION OF THE TOXIGENIC DIATOM PSEUDO‐NITZSCHIA MULTISERIES UNDER PHOSPHATE LIMITATION 1

In both steady‐state continuous culture and batch culture, more DA was produced when alkaline phosphatase activity (APA) was high, and the association of high DA production with high levels of APA and high cellular N:P ratios strongly suggests that phosphate limitation enhances DA production.

Domoic acid production and elemental composition of two Pseudo-nitzschia multiseries strains, from the NW and SW Atlantic Ocean, growing in phosphorus- or nitrogen-limited chemostat cultures.

The data imply that more attention needs to be given to the N:P ratios and concentrations in the waters where these algae occur, as both N and P deficiencies affect DA production and cellular DA concentrations.

CONFIRMATION OF DOMOIC ACID PRODUCTION BY PSEUDO‐NITZSCHIA AUSTRALIS (BACILLARIOPHYCEAE) ISOLATED FROM IRISH WATERS 1

This is the first record of a DA‐producing diatom in Irish waters, and results indicate P. australis may have been the source of DA that has recently contaminated shellfisheries in this area.
