What is algal technology?
This is the most commonly used cultivation condition for algae growth. When algae use organic carbon as both the energy and carbon sources, it is called heterotrophic cultivation. Mixotrophic cultivation is that algae use both organic compounds and inorganic carbon as carbon sources for growth.
What is the role of algae in biotechnology?
o Genetically engineered algae are used to enhance biofuel production and as source of protein and vitamin rich food and fodder. o Algae are used as biofertilizer for crops as rich source of nitrogen, phosphorous, potassium, iodine, iron, calcium, silica and vitamins.
How is algae being used as fuel?
The carbohydrates (sugars) from algae can be fermented to make additional biofuels, including ethanol and butanol, as well as other products such as plastics and biochemicals. Biomass from algae can be used for pyrolysis oil or combined heat and power generation.
Which algae is mostly used in pharmaceuticals?
Chlorophyts, Bryophyta algae are used for the extraction of these healthy and essential fatty acids. N-6 PUFA is a diet rich fatty acid which is derived from the above. The fatty acid content in algae makes it a well-known bioactive compound which is very useful in the pharmaceutical industry.
What are the applications of algae?
Algae can be used for medicine manufacture, sewage treatment and cosmetic manufacture. A green algae species grown in water tanks and exposed to sunlight and heat becomes bright red in color. This can be harvested and used as a natural pigment for foods such as Salmon.
What are microalgae and examples?
Microalgae are microscopic algae. They are single-celled algae that may exist independently or in colonies. They are comprised of the unicellular algal species, e.g. green algae, diatoms, and dinoflagellates.
Is algae safe to take?
Doses up to 19 grams daily have been used safely for up to 2 months. Lower doses of 10 grams daily have been used safely for up to 6 months. Side effects are typically mild and may include nausea, vomiting, diarrhea, headache, and dizziness. But blue-green algae products that are contaminated are possibly unsafe.
Can algae be used as medicine?
Mainly marine algae have been used as food and medicine for many centuries . they are not only used as food but also used as extracts in food, dairy, cosmetics, and industrial uses. Algae is used as one of important medical source due to its antioxidant, anticancer, antiviral properties. .
What is microalgal culture technology?
In recent years, microalgal culture technology is a business oriented line owing to their different practical applications. Innovative processes and products have been introduced in microalgal biotechnology to produce vitamins, proteins, cosmetics, health foods and animal feed.
What are microalgae?
Microalgae are photosynthetic microorganisms that are able to rapidly generate biomass from solar energy, CO 2 and nutrients in bodies of water.
What makes microalgae attractive for bioprocesses?
As photoautotrophs, their simple growth requirements make them attractive for bioprocesses aimed at producing high added-value compounds that are in large demand by the pharmaceutical market. The productivity and biochemical composition of microalgae depend strongly on the mode of cultivation, medium composition, and nutrient profile.
Can microalgal and cyanobacterial cell extracts be used as antibacterial additives?
