Tetradesmus obliquus is a green algae species of the family Scenedesmaceae.[1] It is commonly known by its synonym, Scenedesmus obliquus.[1][2] It is a common species found in a variety of freshwater habitats.[1]

Tetradesmus obliquus forms colonies of two or four (occasionally eight) cells in a single row; in culture, solitary cells are often present. Cells are spindle-shaped, (4–)6–15(–25) μm long and 2.2–9.6(–11) μm wide; cells taper to acute apices and are sometimes slightly asymmetrical.[3] Cells contain a single chloroplast filling the cell, with a pyrenoid present in the center.[4]

This chlorophyte species is notable for the genetic coding of its mitochondria which translate TCA as a stop codon and TAG as leucine.[5] This code is represented by NCBI translation table 22, Scenedesmus obliquus mitochondrial code.[6]

There is increasing interest in T. obliquus for uses in biotechnology, such as biofuel production, aquaculture, and wastewater treatment.[4] Both growth and photosynthesis of T. obliquus are affected by the presence of nano-sized microplastics, such as nano-polystyrene (nano-PS).[7]
