Bacillariales
Bacillariaceae is a family (biology), family of diatoms, the only family in the order (biology), order Bacillariales. Some species of genera such as ''Nitzchia'' are found in halophilic environments; for example, in the seasonally flooded Makgadikgadi Pans in Botswana. Genera This family includes these genera: *''Allonitzschia'' (1) *''Bacillaria'' Johann Friedrich Gmelin, Gmelin (155) *''Crucidenticula'' (8) *''Cylindrotheca (alga), Cylindrotheca'' Gottlob Ludwig Rabenhorst, Rabenh. *''Cymbellonitzschia'' Friedrich Hustedt, Hustedt in Anton Schmidt, A.Schmidt et al.

Nitzschia Kerguelensis
''Nitzschia'' is a common pennate marine and freshwater diatom. In the scientific literature, this genus, named after Christian Ludwig Nitzsch, is sometimes referred to incorrectly as ''Nitzchia'', and it has many species described, which all have a similar morphology. In its current circumscription (taxonomy), circumscription, ''Nitzschia'' is paraphyletic. Occurrence ''Nitzschia'' is found mostly in colder waters, and is associated with both Arctic and Antarctic polar pack ice, 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. The species ''N. frigida'' is found to grow exponentially even at temperatures between −4 and −6 °C. Some ''Nitzschia'' species are also extremophiles by dint of tolerance to high salinity; for example, some halophile, halophilic species of ''Nitzschia'' are ...
