“…As for the major minerals, most macroalgae show abundant contents of sodium (Na), magnesium (Mg), potassium (K), and calcium (Ca). As expected, high Na content was found in C. fragile and C. tomentosum (92.3 and 11.79 mg g −1 dw), (Moreda-Pineiro et al 2012;El-Said and El-Sikaily 2013), while C. iyengarii contains high K (231.7 mg g −1 dw) (Rizvi and Shameel 2004). However, the availability of minerals content in marine macroalgae is influenced by intrinsic and extrinsic factors.…”

A concise review of the bioactivity and pharmacological properties of the genus Codium (Bryopsidales, Chlorophyta)

The genus Codium is one of the most important genera of marine green macroalgae. Its distribution is widespread worldwide and it has a high degree of diversity in species and characteristics. This genus plays an important ecological role in marine ecosystems as it is a primary producer. However, some species in the genus Codium are invasive species and may disturb the functioning of the ecosystem. Economically, Codium has promising potential as a source of diverse nutritional and pharmacological compounds. Codium is edible, has a high nutrient value, and is rich in bioactive compounds. Hence, some species of Codium have been consumed as food and used as herbal medicines in some Asian countries. In recent decades, studies of the bioactivity and pharmacological properties of the genus Codium have attracted the attention of scientists. This review aims to identify gaps in studies analyzing Codium that have been conducted in the past three decades by assessing published research articles on its bioactivity and pharmacological properties. Compounds obtained from Codium have demonstrated significant biological activities, such as immunostimulatory, anticoagulant, anticancer, anti-inflammatory, antioxidant, antiviral, antibacterial, antifungal, antitumor, anti-angiogenic, osteoprotective, and anti-obesity activities. This review provides information that can be used as a future guideline for sustainably utilizing the genus Codium.

“…Seaweeds such as Gracilaria can concentrate minerals from seawater and reach a mineral content 10–20 times higher than that of terrestrial plants [10]. Consequently, they are a valuable source of minerals, with important human nutrition functions [11,12].…”

The present study sought to evaluate the nutritional composition and physicochemical properties of two dried commercially interesting edible red seaweeds, Gracilaria corticata and G. edulis. Proximate composition of the dried seaweeds revealed a higher content in carbohydrates (8.30 g/100 g), total crude protein (22.84 g/100 g) and lipid content (7.07 g/100 g) in G. corticata than in G. edulis. Fatty acids profile showed that G. corticata samples contain higher concentrations of saturated fatty acids, such as palmitic and stearic acids, and polyunsaturated ones such as α-linolenic and docosahexaenoic acids. Contrariwise, G. edulis contained higher amounts of monounsaturated oleic acid. Total amino acid content was 76.60 mg/g in G. corticata and 65.42 mg/g in G. edulis, being the essential amino acid content higher in G. edulis (35.55 mg/g) than in G. corticata (22.76 mg/g). Chlorophyll a was found in significantly higher amounts in G. edulis (17.14 μg/g) than G. corticata, whereas carotenoid content was significantly higher in G. corticata (12.98 μg/g) than in G. edulis. With respect to physical properties, both water- and oil-holding capacities were similar in both seaweeds, whereas swelling capacity was higher in G. edulis. In view of the results, the present study suggests that G. corticata and G. edulis contains important nutrients for human health and are possible natural functional foods.

“…Due attention must be given to the heavy metal concentrations of S. fusiforme, as heavy metal accumulation in ruminants would have adverse effects on health. Brown algae have higher arsenic concentrations than red or green algae, and S. fusiforme is known for its high concentration of arsenic 19,20 . However, most algae-derived arsenics are combined with organic molecules and are collectively known as arsenosugars; however, these are not as toxic as their inorganic forms 21 .…”

Sargassum fusiforme, which is a type of brown algae, can provide fiber and minerals to ruminant diets. In this study, dried S. fusiforme was tested in vitro at four different doses 1, 3, 5, and 10% of the total ration for its effect on ruminal fermentation characteristics, and gas profiles when incubated for 72 h. At a level of 1 and 10%, S. fusiforme supplementation augmented total volatile fatty acid (VFA) concentrations compared to that with 0% supplementation. In addition, total gas, methane, and carbon dioxide emissions significantly decreased at 3 and 24 h of incubation at this dose. An in situ trial was performed for 72 h with S. fusiforme to evaluate it as a potential feed ingredient by comparing its degradation parameters with timothy hay (Phleum pretense). 1H nuclear magnetic resonance spectroscopy profiling was used to identify and quantify metabolites of S. fusiforme. Mannitol, guanidoacetate and ethylene glycol were largely accumulated in S. fusiforme. Moreover, nutritious minerals for feed ingredients were present in S. fusiforme. Whereas a high concentration of arsenic was found in S. fusiforme, it was within the allowable limit for ruminants. Our results suggest that S. fusiforme could represent an alternative, renewable feed ingredient for ruminant diets, with nutritional, as well as environmental, benefits.
