“…The importance of soluble algal carbohydrates such as laminarin, fucoidan and alginate in human and animal nutrition has been attributed to their contribution as dietary fibres and their bioactivity [7,62]. However, algal carbohydrates also have the ability to impact the bioavailability of proteins through formation of carbohydrateprotein complexes.…”

Abstract The chemical profile of biorefined Saccharina latissima, Ascophylum nodosum and Palmaria palmata after carbohydrate and polyphenol extraction was analysed with the aim to evaluate the nutritional aspects of biorefined seaweeds as a novel animal feed supplement. Optimised enzymatic saccharification has been used to show that the protein concentration in the residue of Palmaria palmata and Ascophylum nodosum can be increased by more than two fold. Nutritional value of the residue was further enhanced through an increase in total amino acids and fatty acids. As a consequence of removal of inorganic elements such as sodium, potassium and chloride, the total solid and ash content of all three seaweeds was reduced by around 40%. In contrast, divalent metals such as iron and zinc, as well as silicon accumulated in all three residues. Potentially harmful components such as arsenic and iodine were reduced only in brown biorefined seaweeds, whilst in biorefined P. palmata iodine increased by 39% compared to a 24% decline of arsenic. Polyphenol removal in all three seaweeds was >80% and, in combination with enzymatic saccharification, enhanced protein recovery in A. nodosum. This highlights the potential of biorefinery concepts to generate multiple products from seaweed such as extracts enriched in polyphenols and carbohydrates and residue with higher protein and lipid content.

“…More than 250 tons of dry biomass is produced yearly by the women around Lake Chad, it is the highest volume of Arthrospira (Spirulina) with the cheapest production cost (Algae Industry Magazine report). Arthrospira (Spirulina) platensis were found to produce a novel sulphated polysaccharide named "Calcium-Spirulan" [containing calcium ions, sulphate, uronic acids, rhamnose, 3-O-methylrhamnose (acofriose), 2,3-di-O-methylrhamnose, 3-O-methylxylose, O-rhamnosyl-acofriose and O-hexuronosyl-rhamnose (aldobiuronic acid)] which has been reported to help prevent atherosclerosis because of its antithrombogenic, fibrinolytic, and anti-atherogenic properties [35]. Commercially, various species of Spirulina (aka Arthrospira) such as A (S).…”

Cyanobacteria and microalgae have been cultivated only for a limited number of bioactive compounds or biotechnological applications such as for carotenoids; essential omega-3 fatty acids; phycobilipigments; live cells, unprocessed or minimally processed complete biomass as aqua feed, animal feed and human health supplements as rich sources of proteins, carbohydrates, pigments, vitamins and minerals. However, cyanobacteria and microalgae have been reported through several research investigations as a potential source for various bioactive molecules with marketable nutraceutical and pharmaceutical properties. Therefore, more cultivation of cyanobacteria and microalgae species are waiting for new biotechnological applications. At present, the global demand for microalgal applications is focused on biofuels including biodiesel and bioethanol apart from a handful (mentioned above) of bioactive compounds which are mostly used as nutraceuticals. Thus, microalgal biorefinery is growing rapidly for multiple commodities production from both conventional and photobioreactor-based cultivation for biomass feedstocks for various biotechnological applications. This review presents the cultivation aspects of selected cyanobacteria and microalgae for commercial purposes.
