Bacterial alginates are useful for the production of micro- or nanostructures suitable for medical applications. [8] Sodium alginate (NaC 6 H 7 O 6) is the sodium salt of alginic acid. Sodium alginate is a gum. Potassium alginate (KC 6 H 7 O 6) is the potassium salt of alginic acid. Calcium alginate (CaC 12 H 14 O 12) is the calcium salt of ...
It also has good potential for alginate production since it can yield up to 40% of its dry weight in alginate. [21] Turbinaria also contains fucoidan, a sulfated polysaccharide with antioxidant, anti-inflammatory, and anticancer properties. [22] [23] The Genus Turbinaria is still chemically and pharmacologically underexplored. These brown algae ...
Seaweeds are also harvested or cultivated for the extraction of polysaccharides [4] such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. [5]
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 ...
The Food and Agriculture Organization (FAO) reported that world production in 2019 was over 35 million tonnes. North America produced some 23,000 tonnes of wet seaweed. Alaska, Maine, France, and Norway each more than doubled their seaweed production since 2018. As of 2019, seaweed represented 30% of marine aquaculture. [6]
Sodium alginate (NaAlg) Alginates are the natural product of brown algae and have been used extensively in wound dressing, drug delivery and tissue engineering, as well as food applications. [9] [10] [11] Sodium alginate is an unbranched copolymer of 1,4-linked-β-d-mannuronate (M) and α-l-guluronate (G) sugars.
Nannochloropsis is a genus of alga within the heterokont line of eukaryotes, that is being investigated for biofuel production. One marine Nannochloropsis species has been shown to be suitable for algal biofuel production due to its ease of growth and high oil content (28.7% of dry weight), mainly unsaturated fatty acids and a significant ...
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.
