What are the bioactive compounds of algae?

Algae contain a vast array of biologically active compounds (polyunsaturated fatty acids [PUFAs], vitamins [B group], carotenoids, polyphenols, dietary fiber, polysaccharides, proteins; natural plant growth compounds, such as auxins, gibberellins, and cytokinins [2, 20]) having a potential of industrial application ( …

What is micro algae good for?

Besides proteins, microalgae are source of several valuable compounds with health benefits such as carbohydrates, polyunsaturated fatty acids, essential minerals, and vitamins (24, 25, 28), which can increase the nutritional value of food products upon incorporating.

Which pigment from algae is commonly used in the medical industry?

Phycocyanin is also a pigment obtained from spirulina and an inhibitor of NADPH oxidase with anti-inflammatory activity. It seems that microalgae (especially Spirulina) are effective candidates for the adjuvant therapy of COVID-19 patients [35].

What products are made from algae?

Below are some algae products already on the shelves:

• Abrasives. Diatom “shells” in commercial diatomaceous earth for swimming pool filters.
• Cosmetics. Many skin treatments and cosmetics also contain algae.
• Food Additives.
• Nutritional Supplements.
• Fertilizers.
• Whole algae.

What nutrients are found in algae?

Algae contains high levels of calcium, iron, vitamins A, C, and K, potassium, selenium, and magnesium. Most importantly, it is one of the best natural sources of iodine, a nutrient that is missing from most other foods, and is also essential for a healthy functioning thyroid gland.

What is micro algae?

Microalgae are unicellular photosynthetic micro-organisms, living in saline or freshwater environments, that convert sunlight, water and carbon dioxide to algal biomass. From: Biomass and Bioenergy, 2010.

Which algae is 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 major pigments in algae?

Three major classes of photosynthetic pigments occur among the algae: chlorophylls, carotenoids (carotenes and xanthophylls) and phycobilins. The pigments are characteristic of certain algal groups as indicated below.

What are the industrial uses of algae?

Commercial and industrial algae cultivation has numerous uses, including production of food ingredients such as omega-3 fatty acids or natural food colorants and dyes, food, fertilizer, bioplastics, chemical feedstock (raw material), pharmaceuticals, and algal fuel, and can also be used as a means of pollution control.

Which algae is most nutritious?

Which one is healthier? Both forms of algae contain high amounts of nutrients. However, chlorella is higher in omega-3 fatty acids, vitamin A, riboflavin, iron, magnesium, and zinc.

Which algae is the richest source of protein?

Protein rich algae is spirulina and has high nutritional advantages. Protein content differs among different groups of algae. It is used as a functional food ingredient.

Why is algae biofuel so expensive?

The production cost is high because of the energy required to circulate gases and other materials inside the photo bioreactors where the algae grow. It also takes energy to dry out the biomass, and Solix uses far less water than other companies (see Cutting the Cost of Making Algae by 90%).

What are the three types of microalgae?

Regarding the energy and carbon sources used for their metabolism, microalgae can grow in three different ways: autotrophy, heterotrophy, and mixotrophy [12, 13].

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.

What is economic important algae?

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.
