Chlorococcum is a genus of green algae, in the family Chlorococcaceae. [1] The alga may be useful in the flocculation of lipids from wastewater. [2] It can be found in fresh water, but is more commonly found in soil or subaerial habitats (such as growing on tree bark, wood, stones, or plaster). [3]

Contents

Chlorococcum consists of spherical cells which are single or sometimes borne in small clusters; when colonial, there is sometimes a thin layer of mucilage. Cells contain a single cup-shaped, parietal chloroplast with one pyrenoid. [3]

Chlorococcum reproduces by the formation of autospores or zoospores. [3] The zoospores have two flagella of equal length. [4] Chlorococcum was traditionally defined using morphological characteristics. However, using molecular phylogenetics, the genus was found to be polyphyletic. Therefore, the genus was revised, with several new genera split off (e.g. Alvikia ). [4]

<span class="mw-page-title-main">Chlorophyceae</span> Class of green algae

The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. They are usually green due to the dominance of pigments chlorophyll a and chlorophyll b. The chloroplast may be discoid, plate-like, reticulate, cup-shaped, spiral- or ribbon-shaped in different species. Most of the members have one or more storage bodies called pyrenoids located in the chloroplast. Pyrenoids contain protein besides starch. Some green algae may store food in the form of oil droplets. They usually have a cell wall made up of an inner layer of cellulose and outer layer of pectose.
