Spironemidae is a family of heterotrophic flagellates, in the group Hemimastigophora. They vary in size and shape from the ellipsoid Hemimastix amphikineta to the vermiform Spironema terricola, and are united by the possession of two rows of cilia, called kineties.
Oocystaceae is a family of green algae, in the order Chlorellales. The type genus is Oocystis.
Botryococcus is a genus of green algae. The cells form an irregularly shaped aggregate. Thin filaments connect the cells. The cell body is ovoid, 6 to 10 μm long, and 3 to 6 μm wide. Fossils of the genus are known since Precambrian times, and form the single largest biological contributor to crude oil, and are a major component of oil shales.
Kirchneriella is a genus of green algae in the family Selenastraceae. It is found in freshwater habitats, as phytoplankton or metaphyton.
Schroederia is a genus of green algae in the family Schroederiaceae. Schroederiaceae is a monotypic taxon; Schroederia is its only genus.
Scytonema is a genus of photosynthetic cyanobacteria that contains over 100 species. It grows in filaments that form dark mats. Many species are aquatic and are either free-floating or grow attached to a submerged substrate, while others species grow on terrestrial rocks, wood, soil, or plants. Scytonema is a nitrogen fixer, and can provide fixed nitrogen to the leaves of plants on which it is growing. Some species of Scytonema form a symbiotic relationship with fungi to produce a lichen.
Planktothrix is a diverse genus of filamentous cyanobacteria observed to amass in algal blooms in water ecosystems across the globe. Like all Oscillatoriales, Planktothrix species have no heterocysts and no akinetes. Planktothrix are unique because they have trichomes and contain gas vacuoles unlike typical planktonic organisms. Previously, some species of the taxon were grouped within the genus Oscillatoria, but recent work has defined Planktothrix as its own genus. A tremendous body of work on Planktothrix ecology and physiology has been done by Anthony E. Walsby, and the 55.6 kb microcystin synthetase gene which gives these organisms the ability to synthesize toxins has been sequenced. P. agardhii is an example of a type species of the genus. P. agardhii and P. rubescens are commonly observed in lakes of the Northern Hemisphere where they are known producers of potent hepatotoxins called microcystins.
Lyngbya majuscula is a species of filamentous cyanobacteria in the genus Lyngbya. It is named after the Dane Hans Christian Lyngbye.
The Pseudanabaenaceae are a family of cyanobacteria.
Karel Komárek is a Czech businessman worth $8.18 billion as of February 2023. He is one of the wealthiest Czech citizens and the founder of the investment company KKCG.
Achroonema is a genus of bacteria with uncertain systematics.
Eucapsis is a genus of cyanobacteria belonging to the family Merismopediaceae.
Chlorolobion, sometimes spelled Chlorolobium, is a genus of algae belonging to the family Selenastraceae. The species of this genus are found in freshwater habitats in Europe and America.
Chroococcus is a genus of cyanobacteria belonging to the family Chroococcaceae.
Heteroleibleinia is a genus of algae belonging to the family Pseudanabaenaceae.
Jaaginema is a genus of cyanobacteria belonging to the family Pseudanabaenaceae.
Komvophoron is a genus of cyanobacteria belonging to the family Borziaceae.
Lemmermanniella is a genus of cyanobacteria belonging to the family Synechococcaceae.
Leptolyngbya is a genus of cyanobacteria belonging to the family Leptolyngbyaceae.
Limnococcus is a genus of cyanobacteria belonging to the family Chroococcaceae.
