The Chrysophyceae, usually called chrysophytes, chrysomonads, golden-brown algae or golden algae, are a large group of algae, found mostly in freshwater. [3] Golden algae is also commonly used to refer to a single species, Prymnesium parvum , which causes fish kills .
Chrysophyta or golden algae is a term used to refer to certain heterokonts. Dinobryon sp. from Shishitsuka Pond, Tsuchiura, Ibaraki Prefecture, Japan. It can be used to refer to: Chrysophyceae (golden algae), Bacillariophyceae (diatoms), and Xanthophyceae (yellow-green algae) together. [1] E.g., Pascher (1914). [2]
The synurids were originally included among the golden algae in the order Ochromonadales as the family Mallomonadaceae or as the family Synuraceae . They were formally defined as a separate group by Andersen in 1987, who placed them in their own class Synurophyceae , based on an earlier approach of more narrowly defining major lineages of ...
Ochromonadales is an order of golden algae (class Chrysophyceae), a group of photosynthetic heterokonts (phylum Ochrophyta). [8] It initially contained numerous families united only by being primarily monadoid (flagellate), palmelloid or amoeboid throughout their life cycle.
Some unicellular species of green algae, many golden algae, euglenids, dinoflagellates, and other algae have become heterotrophs (also called colorless or apochlorotic algae), sometimes parasitic, relying entirely on external energy sources and have limited or no photosynthetic apparatus.
More informally known as an Apple Snail, or Gold Inca Snails, these healthy diners will feed on ordinary fish food and waste, making these algae eaters a popular choice in many aquariums.
Each cell contains two plastids aligned with the long axis of the cell; they impart a distinctive golden color to the cells, which comes from chlorophyll c 1 and fucoxanthin. Cells are covered with scales made of silica. Two flagella are present. [6] Identification of species depends on the morphology of the scales.
