Bacillariaceae
Bacillariaceae is a family of diatoms in the phylum Heterokontophyta, the only family in the order Bacillariales. Some species of genera such as ''Nitzchia'' are found in halophilic environments; for example, in the seasonally flooded Makgadikgadi Pans in Botswana.

Halophilic
The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. While most halophiles are classified into the domain Archaea, there are also bacterial halophiles and some eukaryotic species, such as the alga ''Dunaliella salina'' and fungus ''Wallemia ichthyophaga''. Some well-known species give off a red color from carotenoid compounds, notably bacteriorhodopsin. Halophiles can be found in water bodies with salt concentration more than five times greater than that of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Urmia Lake in Iran, the Dead Sea, and in evaporation ponds. They are theorized to be a possible analogues for modeling extremophiles that might live in the salty subsurface water ocean of Jupiter's Europa and similar moons. Classification Halophiles are categorized by the extent of their halotolerance: slight, moderate, or extreme. Slight halophiles prefer 0.3 to 0.8 M (1.7 to 4.8%†...

Hantzschia
''Hantzschia'' is a genus of diatoms belonging to the family Bacillariaceae. The genus was first described by Albert Grunow Albert Grunow (3 November 1826, Berlin – 17 March 1914, Berndorf, Lower Austria) was a German-Austrian chemist and phycologist. He specialized in the study of diatoms. From 1851 he worked as a chemist in a metal works factory in Berndorf. ... in 1877. The genus name of ''Hantzschia'' is in honour of Carl August Hantzsch (1825 - 1886), who was a German botanist (Algology).

Bacillaria
''Bacillaria'' is a diatom genus in the family Bacillariaceae. Species *'' Bacillaria paradoxa'' Gmelin 1788 *'' Bacillaria paxillifer'' ( O.F. Müller) Hendey (1951) Lifecycle This genus is photosynthetic, and reproduces sexually and asexually. Description Cells are elongated and motile, sliding along each other, in stacked colonies. Cells are rectangular in girdle view (when in colonies), and lanceolate in valve view. Raphe system is slightly keeled and runs from pole to pole. Two large plate-like chloroplasts are present, one near each end of the cell. The nucleus is located centrally. Cells are yellow-brown in colour. Fibulae are strong, and the valve surface is covered in transverse parallel structures called striae.

Nitzschia Kerguelensis
''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. Occurrence ''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. The species '' N. frigida'' is found to grow exponentially even at temperatures between −4 and −6 °C. Some ''Nitzschia'' species are also extremophiles by dent of tolerance to high salinity; for example, some halophilic species of ''Nitzschia'' are found in the Makgadikgadi Pans in Botswana.C.

Friedrich Hustedt
Friedrich Hustedt (1886 – 1 April 1968) was a German teacher and botanist, best known for his diatom systematics research. He was born and grew up in Bremen, Germany. He taught school for 32 years, in 1924 becoming the head teacher of the school at Hauffstraße in Bremen. Hustedt initially pursued his interest in diatoms as a hobby, but his standing in the scientific community grew rapidly; thus, in 1939 he left school to study diatoms full-time. He described over 2000 diatom taxa and eventually amassed the largest private diatom collection in the world which is currently housed at the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany. The phycological Phycology () is the scientific study of algae. Also known as algology, phycology is a branch of life science. Algae are important as primary producers in aquatic ecosystems.

Friedrich Traugott Kützing
Friedrich Traugott Kützing (8 December 1807 in Kalbsrieth, Ritteburg – 9 September 1893) was a German pharmacist, botanist and phycologist. Despite his limited background in regard to higher education, Kützing made significant scientific contributions. In 1833, he demonstrated differences between diatoms and desmids, thus separating the two groups into families of their own. Also, independent of Charles Cagniard-Latour (1777–1859) and Theodor Schwann (1810–1882), he was among the first to provide comprehensive answers in regard to yeast and the role it played in fermentation. In 1849, he published ''Species Algarum'', a massive work that provided descriptions for 6000 species of algae. He is the binomial authority, taxonomic authority of the genera ''Syringodium'' (family Cymodoceaceae) and ''Phlebothamnion'' (family Ceramiaceae). Early life As a young man, he worked in several pharmacies in Germany, also serving as assistant for a few semesters at the chemical-pharma ...
