“…According to their color pigments, microalgae are usually classified into green, brown, and red. As a result, these microalgae are divided into four classes: green microalgae (chlorophytes), blue microalgae (cyanobacteria), red microalgae (rhodophytes), and brown microalgae (chromophytes) (see [2] and [6]).…”

The cyanobacterium Arthrospira platensis (A. platensis)—a genus of nonheterocystous filamentous cyanobacteria—is used in industrial applications and as a food supply. The current research work aims to study the physicochemical characteristics of A. platensis indigenous to the Moroccan Atlantic coast at Laayoune (Foum El Oued lagoon). The contents of proteins, carbohydrates, vitamins, lipids, minerals, heavy metals, energy value, humidity, ash, pigments, and tannins in A. platensis were investigated using protocols as described in the earlier literature. The values of protein, carbohydrate, and lipid contents in A. platensis were 58.9 ± 0.07, 14.67, and 45.54% respectively. The values of vitamins B2 and B3 dosed in A. platensis were 1.31 ± 0.19 and 30.8 ± 0.001 mg/kg, respectively. The values of heavy metals including lead and chromium were 70 ± 4.5 and 5 ± 0.5 PPB (parts-per-billion), respectively; however, no trace concerning cadmium was detected. The values of energy value, humidity, and ash content were 346.48 ± 0.21, 11.6 ± 0.17%, and 9.1 ± 0.21% kcal/100 g, respectively. The results of pigment content showed the presence of chlorophyll b, chlorophyll a, and carotenoids of 37.506 ± 3.38, 26.066 ± 3.08, and 9.52 ± 0.22 mg/g, respectively. The results obtained revealed that A. platensis indigenous to the Moroccan Atlantic coast at Laayoune was found to be very rich in proteins, carbohydrates, vitamins, minerals, ash, and pigments and lower in heavy metals and saturated fats when compared with species investigated in the literature. Thus, A. platensis indigenous to the Moroccan Atlantic coast at Laayoune fulfills the requirements for being used as dietary supplements.

Growing Ulva (Chlorophyta) in integrated systems as a commercial crop for abalone feed in South Africa: a SWOT analysis

et al. 2008

View full text Add to dashboard Cite

Over 1,000t fresh weight of Ulva was cultivated on South African abalone farms in 2007, primarily for feed, but in one case to allow partial re-circulation by nutrient removal. The potential of this new commercial crop is analysed. Material is collected from natural free-floating populations and at least four species are commonly grown, with different ecophysiological characteristics. A brown epiphyte, Myrionema strangulans, causes a disease of the Ulva, which is currently managed by farmers by restocking. The main potential threat is that some farmers are wary of integrated systems, fearing they may promote disease in abalone, although Ulva has been grown in abalone effluent and fed back to the abalone on one farm for 6 years without adverse effects. Opportunities exist for the expansion of Ulva cultivation via further spread of the abalone industry, the inclusion of seaweed raceways in proposed fish-farming activities, or the potential for the inclusion of high quality cultivated Ulva as a constituent in aquafeed. A conservative estimate of production over a full year from these raceway systems was 26.1 g dw m −2 day −1 (2006) and 19.7 g dw m −2 day −1 (2007), similar to maximum figures for total annual microalgal biomass production in outdoor systems.

“…Algae can be used in normally food use and special regimes with a unique place in the nutrition compared to other vegetables and other sources of nutrients (Denis et al, 2010;Marfaing & Lerat, 2007). Phycobiliproteins have antioxidant properties (Holdt & Kraan, 2011) and could be used in the prevention or treatment of degenerative diseases: cardiovascular, certain cancers, and eye linked to oxidative stress.…”

Phycobiliproteins are pigment-protein complexes, brilliant-colored and water soluble, existing in cyanobacteria and red algae. They have a great interest in food technology, food supplements, and pharmaceutical applications. Therefore it is important to have a fast, easy, and reliable method to determine the content of phycoerythrin (PE), phycocyanin (PC), and allophycocyanin (APC) in red algae. The samples are ground, extracted in phosphate buffer (pH 6.8), centrifuged, and the fluorescence scan of the supernatant is recorded. Optimum excitation-emission wavelength intervals (Dl) for synchronous spectrofluorimetric analysis of the three phycobiliproteins were 10 nm for PE (LD ¼ 10.9 6 10 73 mg/l) and APC (LD ¼ 0.5 mg/l) and 40 nm for PC (LD ¼ 0.77 mg/l). Algae analyzed contain PC and PE.
