What is scenedesmus Obliquus classified as?

What is scenedesmus Obliquus classified as?

Scenedesmus obliquus is a green algae species of the genus Scenedesmus. This chlorophyte species is notable for the genetic coding of its mitochondria which translate TCA as a stop codon and TAG as Leucine.

What is scenedesmus Obliquus used for?

The microalga Scenedesmus obliquus has been used in postoperative recovery, assisting in coagulation of the skin surface. The extracts of the diatom Asterionella notata have an antifungal and antiviral activity. Toxic algae have been used as a depressant vessel, similar to tetrodotoxin found in fish (Richmond, 1990).

Is scenedesmus motile?

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.

How does scenedesmus Obliquus reproduce?

Colonies reproduce asexually by successive divisions of the protoplast within the parent cell wall, and when progeny are released, the parent wall remains. Young spiny colonies have all of their ornamentation upon their release.

Is Scenedesmus harmful?

The green alga Scenedesmus subspicatus CHODAT was cultivated as the test organism. Twenty-five substances were examined according to the standardized test procedure. Thus, they prove very/highly toxic to the cell multiplication of Scenedesmus subspicatus.

Is Scenedesmus 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.

Is scenedesmus unicellular?

Scenedesmus is a small, nonmotile colonial green alga consisting of cells aligned in a flat plate. The colonies most often have two or four cells, but may have 8, 16, or rarely 32 and are occasionally unicellular.

Is Scenedesmus unicellular?

What do you need to know about AlgaeBase?

AlgaeBase is a comprehensive taxonomic database of information on algae that includes terrestrial, marine and freshwater organisms. Users may consult this resource to check taxonomies or nomenclature, obtain information pertaining to geographic distributions, and view or download images.

What is the difference between Desmodesmus and Acutodesmus?

Hegewald denotes Acutodesmus, Desmodesmus, and Scenedesmus as the three major categories. Acutodesmus is characterized as having acute cell poles, while Desmodesmus and Scenedesmus have obtuse/truncated cell poles (differentiated by the presence or absence of spines respectively).

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.

How many species of Scenedesmus are there in the world?

Scenedesmus is a genus of green algae, in the class Chlorophyceae. They are colonial and non-motile. 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.
