Is Scenedesmus autotrophic or heterotrophic?
Scenedesmus is known to have high biomass productivity among green algae, and has been actively researched for its use for bio-diesel production. Its heterotrophic production of biomass and lipid in optimized conditions is reported to have higher efficiency than its autotrophic production.
Is Scenedesmus rich in protein?
Besides, a tremendously high of protein content was found in 10%WM with 50.72% while high lipid content was found in 25%WM with 26.7%. This indicates that microalgae Scenedesmus sp. biomass was rich in protein but lower in lipid straightly can be a potential application for bio-based product such as fish feedstock.
Is Scenedesmus photosynthetic?
Abstract: Heterotrophically grown cells of a newly isolated strain of Scenedesmus sp. retained their photosynthetic pigment content after prolonged darkness.
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.
Why does Scenedesmus include 4 8 or 16 cells?
These even numbered colonies are due to its reproduction. Since they are very small, they are vulnerable to grazers. To defend against grazers, they form colonies for additional protection other than their spines.
What can scenedesmus Obliquus be 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 unicellular or multicellular?
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.
Why do scenedesmus have 4 8 or 16 cells?
Is scenedesmus a Desmid?
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.
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. Each cell contains a single parietal, plate-like chloroplast with a single pyrenoid.
