Is Scenedesmus SP A Desmid?
Scenedesmus sp. are small forms usually comprised of four cells, but some species may have up to twelve cells. Species of Micrasterias typically are among the largest desmids. In life, the smaller Micrasterias sp.
How is scenedesmus Obliquus classified?

Is Scenedesmus eukaryotic or prokaryotic?
discovered that the eukaryotic unicellular green algae Scenedesmus obliquus is able to evolve molecular hydrogen by means of a hydrogenase in light under anaerobic conditions.
Is Scenedesmus harmful?
In the Scenedesmus cell multiplication inhibition test, 68 potentially hazardous substances were examined to determine the effect concentrations (EC). Thus, they prove very/highly toxic to the cell multiplication of Scenedesmus subspicatus.
Is s Obliquus capable of movement?
Scenedesmus is a genus of green algae, in the class Chlorophyceae. They are colonial and non-motile.
What are the characteristics of Scenedesmus?
Scenedesmus species are nonmotile and usually consist of 4, 8, 16, or 32 cells arranged in a row. Some species are spiny or feature bristles. Reproduction is by nonmotile spores called autospores.
What is S Obliquus used for?
In the paper published by Patnaik and Mallick (2015), the green microalga Scenedesmus obliquus was used as a model organism to produce biodiesel and other industrially important co-products such as β-carotene, omega-3 fatty acids, glycerol and bioethanol in a sequential process in the designed algal refinery, but the …
When did the genus Scenedesmus get its name?
The first species of the genus Scenedesmus was described by Turpin in 1828 and placed in family Scenedesmaceae by Oltsmanns in 1904 (Hegewald 1997 ). The genus name was given by Meyen in 1829 and studied by many researchers for more than 100 years using light microscopy (Hegewald 1997). …
How many species of Scenedesmus are there in the world?
Currently, there are 74 taxonomically accepted species of Scenedesmus. Additionally, several subgenera have been identified, but vary according to the source. Hegewald denotes Acutodesmus, Desmodesmus, and Scenedesmus as the three major categories.
What kind of ornamentation does a Scenedesmus have?
The last major category of ornamentation is rosettes that are common to many Scenedesmus species. Rosettes are ring-shaped structures enclosing small mounds on the cell surface and are usually sitting upon a thicker layer of cell wall than the surrounding areas. No potential function for these structures has been suggested.
What can Scenedesmus be used for in wastewater treatment?
Bio-hydrogen production research using Scenedesmus is actively spurred by its applications to wastewater treatment. (See subsequent section on waste management by Scenedesmus). Scenedesmus is known to have high biomass productivity among green algae, and has been actively researched for its use for bio-diesel production.
