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 the economic importance of Algin?
Algin is a calcium magnesium salt of alginic acid present in the intercellular substance of the Phaeophyceae. Because of its special colloidal properties alginic acid and its derivatives find considerable use in industry.
What are the economic importance of Phycophyta?
Algae are economically important in a variety of ways. The natural substance can be used as a food source, a fodder, in fish farming, and as a fertilizer. It also plays a key role in alkaline reclaiming, can be used as a soil binding agent, and is used in a variety of commercial products.
Are Scenedesmus unicellular or multicellular?
Microalgae (Scenedesmus sp.) in multicellular (left) and unicellular (right) states. Take-home message 2: Interactions with other organisms can drive multicellularity. As mentioned above, becoming multicellular can be a response to competition or predation by other organisms.
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 locomotion?
Scenedesmus is a genus of green algae, in the class Chlorophyceae. They are colonial and non-motile.
What is the importance of algae in daily life?
Algae are the most important photosynthesizing organisms on Earth. They capture more of the sun’s energy and produce more oxygen than all plants combined. They form the foundation of most aquatic food webs, which support an abundance of animals.
What are the economic importance of bacteria?
Bacteria are economically important as these microorganisms are used by humans for many purposes. The beneficial uses of bacteria include the production of traditional foods such as yogurt, cheese, and vinegar. Microbes are also important in agriculture for the compost and fertilizer production.
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).
