“…For example, a sugar present in green algae is sucrose [136], while red algae present floridoside, isofloridoside and digeneaside [137][138][139]. In addition, mannitol, which is an authorized food and drug ingredient, can represent 3-30% of brown seaweed's dry weight [131,[140][141][142][143]. However, when ingested, only 25% of mannitol is absorbed by the organism and thereafter completely excreted in the urine; the remaining 75% is fermented by the microbiota [135].…”

“…Particularly in Laminariales, such as Saccharina latissima (formerly known as Laminaria saccharina) and L. digitata, there is the polysaccharide laminarin, which can reach 35% (usually 10-30%) of the seaweed dry matter [143,156]. Additionally, when ingested, laminarin can be partially or completely fermented by the endogenous intestinal microflora [157].…”

The world population is continuously growing, so it is important to keep producing food in a sustainable way, especially in a way that is nutritious and in a sufficient quantity to overcome global needs. Seaweed grows, and can be cultivated, in seawater and generally does not compete for arable land and freshwater. Thus, the coastal areas of the planet are the most suitable for seaweed production, which can be an alternative to traditional agriculture and can thus contribute to a reduced carbon footprint. There are evolving studies that characterize seaweed’s nutritional value and policies that recognize them as food, and identify the potential benefits and negative factors that may be produced or accumulated by seaweed, which are, or can be, dangerous for human health. Seaweeds have a high nutritional value along with a low caloric input and with the presence of fibers, proteins, omega 3 and 6 unsaturated fatty acids, vitamins, and minerals. Moreover, several seaweed sub-products have interesting features to the food industry. Therefore, the focus of this review is in the performance of seaweed as a potential alternative and as a safe food source. Here described is the nutritional value and concerns relating to seaweed consumption, and also how seaweed-derived compounds are already commercially explored and available in the food industry and the usage restrictions to safeguard them as safe food additives for human consumption.

“…Regarding the macroalgae content in micronutrients, they are a good source of vitamins, especially of the B-group representatives (i.e., B 1 , B 12 ), as well as the lipophilic vitamins A and E (tocopherol) [ 13 , 15 , 16 , 17 ]. The richness in vitamin B 12 propels the macroalgae-based products as dietary supplements for a vegan lifestyle, considered to be at risk for vitamin B 12 deficiency [ 18 ].…”

Nowadays, one of the most important research directions that concerns the scientific world is to exploit the earth’s resources in a sustainable way. Considering the increasing interest in finding new sources of bioactive molecules and functional products, many research studies focused their interest on demonstrating the sustainability of exploiting marine macroalgal biomass as feedstock for wastewater treatment and natural fertilizer, conversion into green biofuels, active ingredients in pharmaceutical and nutraceutical products, or even for the production of functional ingredients and integration in the human food chain. The objective of the present paper was to provide an overview on the recent progress in the exploitation of different macroalgae species as a source of bioactive compounds, mainly emphasizing the latter published data regarding their potential bioactivities, health benefits, and industrial applications.

“…In this study, almost all the algal extracts tested showed antifungal activity against G. boninense proving that extractable materials from marine algae collected from Port Dickson, Malaysia contained bioactive compounds with potential remedial interest. The broad range of classes of bioactive compounds found in seaweeds are carotenoids (Yip et al, 2014), phenolics (Airanthi et al, 2011;Matanjun et al, 2008), alkaloids (Dheeb, 2015;Pawar and Nasreen, 2016), sterols (Abdel-Aal et al, 2015), essential fatty acids (Fayaz et al, 2005;Rajasulochana et al, 2013), vitamins (Hamid et al, 2015), polyphenols, dietary fiber, polysaccharides and proteins (Ibañez et al, 2012). A Kruskal-Wallis H test was conducted to know the effect of solvents and species of extracts towards growth reduction percentage of G. boninense.…”

Basal stem rot (BSR) disease is the most devastating disease in oil palm which is caused by a fungal pathogen, Ganoderma boninense. However, to date, there is no reliable control for this disease. This study investigated the antifungal potential of seaweed extracts against G. boninense and screening of the compounds possessing this antifungal activity. Four seaweed species namely cfSargassum oligocystum, Caulerpa racemosa, Caulerpa racemosa var. lamouroxii and cfHalimeda macrophysa were collected from Teluk Kemang, Port Dickson, Malaysia and their antifungal potential against G. boninense were evaluated. Two solvents with different polarities were used for crude extraction namely methanol and chloroform. Antifungal assay using crude methanolic and chloroform extracts from these seaweed species were carried out at various concentrations using the poisoned food technique. Caulerpa racemosa var. lamouroxii chloroform extract showed strong antifungal activity against G. boninense with 27.44% inhibition of the fungus followed by C. racemosa methanolic extract with 26.92% inhibition of the fungus at the lowest extract concentration of 0.25 mg/mL. The extracts were subjected to Gas Chromatography-Mass Spectrometry analysis and the dominant bioactive compounds detected in both extracts were phytol and l-(+)-ascorbic acid 2,6-dihexadecanoate which were also found in plant extracts showing antimicrobial activities in previous studies. The findings suggested that local Malaysian seaweed species have high potential as a source of antifungal compounds which could be useful specifically for the application in the oil palm industry.
