Spirulina is the dried biomass of cyanobacteria (blue-green algae) that can be consumed by humans and animals. The three species are Arthrospira platensis , A. fusiformis , and A. maxima . Cultivated worldwide, Arthrospira is used as a dietary supplement or whole food . [ 1 ]
Iran started investigating the production of algae from 2000. Scientific evidence shows that south Iran is the richest area in the world for cultivating algae, because of high humidity, sunny weather, large unused area and salty water. [2] The first version of algae based biofuel will become available for industrial purposes in 2015. [3]
The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. [6] Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while others can have a laxative and electrolyte-balancing effect. [7]
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care. Alginates are used in industrial products such as paper coatings, adhesives, dyes, gels, explosives and in processes such as paper sizing, textile printing, hydro-mulching and drilling.
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
Recent studies around the world look at the algae usage for treating wastewater as a way to become more sustainable. [12] The utilization of algae as food is very common in East Asian regions [13] and is making an appearance around the world for uses in feedstock and even pharmaceuticals due to their high value products. [9]
Single-cell proteins (SCP) or microbial proteins [1] refer to edible unicellular microorganisms.The biomass or protein extract from pure or mixed cultures of algae, yeasts, fungi or bacteria may be used as an ingredient or a substitute for protein-rich foods, and is suitable for human consumption or as animal feeds.
