This classification treats diatoms as a phylum (Diatomeae/Bacillariophyta), accepts the class Mediophyceae of Medlin and co-workers, introduces new subphyla and classes for a number of otherwise isolated genera, and re-ranks a number of previously established taxa as subclasses, but does not list orders or families.
Previous versions of the Adl et al., 2019 classification appeared in Adl et al. 2005 and Adl et al. 2012, [18] [19] also in the chapter "Bacillariophyta" by Mann, Crawford & Round in the 2017 Handbook of the Protists edited by Archibald et al., [22] in which some groups later named as formal taxa are listed under informal names (leptocylindrids ...
Within the diatoms (Bacillariophyta), harmful effects can be due to physical damage or to toxin production. Centric diatoms like Chaetoceros live as colonial chains of cells with long spines (setae) that can clog fish gills, causing their death.
Three diatom species were sent to the International Space Station, together with the huge (6 mm length) diatoms of Antarctica and the exclusive colonial diatom, Bacillaria paradoxa.
Gyrista was first described in 1998 by protistologist Thomas Cavalier-Smith in his work A revised six-kingdom system of life, originally as a superphylum containing two phyla: Ochrophyta, the heterokont algae; and Bigyra, which then contained the pseudofungi and bigyromonads together with the opalines.

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources. Novellas are works of prose fiction longer than a short story but shorter than a novel. Several novellas have been recognized as among the best examples of the literary form. Publishers and literary award societies typically consider a ...
Some species of Sphingomonadaceae are known to degrade some aromatic compounds.This makes the bacteria of interest to environmental remediation. [8]The diverse metabolic capacity of genera within the Sphingomonadaceae family, such as Sphingobium, Novosphingobium, [a] and Sphingopyxis enable these genera to adapt to and be abundant in the presence of bisphenol A.
