Trebouxiophyceae genera

Chlorella is a genus of about thirteen species of single-celled or colonial green algae of the division Chlorophyta. The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella. Their chloroplasts contain the green photosynthetic pigments chlorophyll-a and -b. In ideal conditions cells of Chlorella multiply rapidly, requiring only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce.

Prototheca is a genus of algae in the family Chlorellaceae. While this genus is a member of the green algae, all Prototheca no longer have chloroplasts and therefore their photosynthetic ability. Some species can cause protothecosis in humans and various vertebrates.

Trebouxia is a unicellular green alga. It is a photosynthetic organism that can exist in almost all habitats found in polar, tropical, and temperate regions. It can either exist in a symbiotic relationship with fungi in the form of lichen or it can survive independently as a free-living organism alone or in colonies. Trebouxia is the most common photobiont in extant lichens. It is a primary producer of marine, freshwater and terrestrial ecosystems. It uses carotenoids and chlorophyll a and b to harvest energy from the sun and provide nutrients to various animals and insects.

Zoochlorella (: zoochlorellae) is a colloquial term for any green algae that lives symbiotically within the body of an aquatic invertebrate animal or a protozoan.

Prasiola is a genus of macroscopic green algae, found in a variety of habitats ranging from terrestrial, freshwater, to marine. The genus has a cosmopolitan distribution, ranging from the Arctic to the Antarctic.

Oocystis is a planktonic genus of mostly freshwater green algae of the family Oocystaceae. It is the type genus of its family. Oocystis is mostly found in freshwater habitats and has a cosmopolitan distribution. A few species are found in terrestrial, such as wet rocks, or in marine waters.

Botryococcus is a genus of green algae. It is a microscopic or semi-microscopic alga that is found in freshwater habitats worldwide. It consists of colonies of cells in an irregular, gelatinous matrix.

Microthamnion is a genus of green algae in the family Microthamniaceae. It is found in freshwater habitats around the world, preferably with low levels of pollution; it is typically attached to solid substrates.

Acanthosphaera is a genus of green algae, in the family Chlorellaceae. It contains the sole species Acanthosphaera zachariasii, although some sources list a second species, Acanthosphaera tenuissima. It is widely distributed, in freshwater habitats and exists as phytoplankton.

Golenkiniopsis is a genus of green algae in the family Chlorellaceae. It is found in freshwater plankton worldwide, but is rare.

Micractinium is a genus of microscopic green algae in the family Chlorellaceae. Species of the genus Micractinium are found as phytoplankton, and are commonly found in freshwater habitats around the world. A few species are found as endosymbionts of ciliates. There is increasing interest in Micractinium due to its high growth rate and lipid production.

Dictyosphaerium is a genus of green algae, in the family Chlorellaceae. It occurs in freshwater habitats around the world and is planktonic. The name comes from the Greek roots diktyon, meaning "net", and sphaira, meaning "ball", referring to its morphology.

Stichococcus is a genus of green algae in the family Stichococcaceae. It is a very common algal genus found in a variety of habitats, such as tree trunks, soil, snow, freshwater and marine habitats. One species, Stichococcus bacillaris is economically important as it produces fatty acids useful for biofuels.

Coccomyxa is a genus of green algae in the family Coccomyxaceae. This genus is defined by their small, elliptical to spherical shape, and the presence of a simple parietal chloroplast. These features, along with their occurrence in various lifestyles such as free-living, parasitic, or as , have been used to identify more than 40 species. Using additional morphological features, such as brown akinetes formation, allows for the differentiation between Coccomyxa and the genus Pseudococcomyxa, as they tend to share some morphological characteristics like the general cell shape and one-sided mucila

Actinastrum is a genus of freshwater green algae. It was first described by Gustaf Lagerheim in 1882. Members of the genus are commonly found in eutrophic freshwater ponds and lakes, and have a cosmopolitan distribution.

Helicosporidium is a genus of colorless, pathogenic algae in the class Trebouxiophyceae of the green algae. It is a parasite found in the gut of insects, and a close relative of Prototheca.

genus of algae

Gloeotila is a genus of green algae in the class Trebouxiophyceae. It is typically found in freshwater habitats, either attached to surfaces or planktonic, or found in soil.

Koliella is a genus of green algae in the order Prasiolales. Members of this genus are found in freshwater plankton, but some are also found on snow and ice.

Diplosphaera is a genus of green algae in the family Stichococcaceae.

Lagerheimia is a genus of green algae in the family Oocystaceae. It is commonly found in freshwater habitats all over the world, although some species are rare and have only been recorded from Europe or the United States.

Rosenvingiella is a genus of green algae in the family Prasiolaceae. Members of this genus are found in marine (particularly intertidal) or terrestrial habitats.

Choricystis is a genus of green algae in the class Trebouxiophyceae, considered a characteristic picophytoplankton in freshwater ecosystems. Choricystis, especially the type species '', has been proposed as an effective source of fatty acids for biofuels. Choricystis algacultures have been shown to survive on wastewater. In particular, Choricystis'' has been proposed as a biological water treatment system for industrial waste produced by the processing of dairy goods.

Leptosira is a genus of green algae, in the class Trebouxiophyceae. It is epiphytic on aqutic plants, and is found in freshwater habitats or in soil.
