Nitzschia is found mostly in colder waters, and is associated with both Arctic and Antarctic polar sea ice, where it is often found to be the dominant diatom. Nitzschia includes several species of diatoms known to produce the neurotoxin known as domoic acid, a toxin responsible for the human illness called amnesic shellfish poisoning .

Nitzschia. Raphe eccentric, within a keel; Keel supported by internal fibulae; Raphe of each valve on opposite sides of the frustule

Pseudo-nitzschia is a marine planktonic diatom genus that accounts for 4.4% of pennate diatoms found worldwide. [1] Some species are capable of producing the neurotoxin domoic acid (DA), which is responsible for the neurological disorder in humans known as amnesic shellfish poisoning (ASP). Currently, 58 species are known, 28 of which have been ...

Nitzschia is a relatively large genus with hundreds of freshwater and marine species. Most species are epipelic in microhabitat but Nitzschia also contains planktonic, epilithic, and epiphytic species.

Aug 2, 2021 · A near-complete diploid nuclear genome and accompanying circular mitochondrial and chloroplast genomes have been assembled from the elite commercial diatom species Nitzschia inconspicua.

Freshwater or marine; can be epiphytic on sand or planktonic. Nitzschia navis-varingica has been found to produce domoic acids in the vicinity of Japan, Philippines, Vietnam and Australia. Mainly in tropical to subtropical marine waters. Hassall, A.H. 1845.

Nitzschia alpina is widely distributed in lakes and streams in the Northern Rocky Mountains, where mean pH is 7.8 and mean specific conductance is 266 µS/cm.

Nitzschia Hassall, 1845 (Bacillariophyceae) is one of the most numerous and various non-monophyletic genera where several phylogenetic clades and morphological sections can be distinguished (Rimet et al. 2011; Mann et al. 2021; Guiry 2023).

Nitzschia is a common pennate marine diatom. In the scientific literature, this genus, named after Christian Ludwig Nitzsch, is sometimes termed Nitzchia, and it has many species described, which all have a similar morphology.
