Isochrysis is a genus of haptophytes. [1] [2] Until recently this genus was also thought to contain the 'T-iso' algae frequently used in aquaculture; that species has been reclassified as Tisochrysis lutea . [3]
There are six species: [1]
The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of unicellular algae found in freshwater and moist terrestrial environments, less common today than they were during the Proterozoic. The stated number of species in the group varies from about 14 to 26. Together with the red algae (Rhodophyta) and the green algae plus land plants, they form the Archaeplastida.
Isochrysis galbana is a species of Haptophyta. It is the type species of the genus Isochrysis. It is an outstanding food for various bivalve larvae and is now widely cultured for use in the bivalve aquaculture industry. This unicellular is investigated for its high amount of fucoxanthin. The Isochrysis galbana extract is said to have certain cosmetic and hair-growth properties when using hexane, ethyl acetate, ethanol, water, methanol, or isopropanol as extractants. I. galbana has a chloroplast, whose genome sequence has been published in 2020.
Carteria is a genus of green algae in the family Chlamydomonadaceae. Carteria are similar in morphology to the common genus Chlamydomonas and differ by having four, rather than two, flagella at the vegetative stage.
Chaetophora is a genus of green algae in the family Chaetophoraceae.
Hemiflagellochloris is a monotypic genus of green algae in the family Volvocaceae. It has only one known species, Hemiflagellochloris kazakhstanica.
Pseudochlorella signiensis is a species of green algae in the family Koliellaceae. Pabia signiensis, the only species in the genus Pabia, is regarded as a synonym. Pabia was sunk into Pseudochlorella in 2016.
Trichosarcina is a genus of green algae in the order Ulotrichales. Filoprotococcus was once regarded as a synonym. However, Filoprotococcus is now considered valid in its own right. Trichosarcina is considered to be of uncertain validity.
Chlorohippotes is a genus of green algae, in the family Chlorococcaceae. It contains a single species, Chlorohippotes tenax.
Sykidion is a genus of green algae. Pseudoneochloris is a synonym of this genus. As of March 2022, Sykidion was the only genus in the family Sykidiacaeae, which was the only family in the order Sykidiales.
Chlorokybus is a multicellular (sarcinoid) genus of basal green algae or charophyte. It has been classified as the sole member of the family Chlorokybaceae, which is the sole member of the order Chlorokybales, in turn the sole member of the class Chlorokybophyceae. It grows on soil and rock surfaces, and is rare.
Mesostigma is a genus of unicellular biflagellate freshwater green algae, with a single species Mesostigma viride, covered by an outer layer of basket‐like scales instead of a cell wall. As of February 2022, AlgaeBase classified it as the only genus in the family Mesostigmataceae, the only family in the order Mesostigmatales, the only order in the class Mesostigmatophyceae. It is now considered to be one of the earliest diverging members of green plants/algae (Viridiplantae).
Myrmecia is a genus of green algae that is associated with lichens.
Cyanonephron is a genus of cyanobacteria in the family Synechococcaceae.
Tisochrysis lutea is a species of Haptophyta formerly known as Isochrysis affinis galbana (Tahiti isolate) or 'T-iso'.
