“…Red seaweed is home to a vast array of species due to its varied life cycles and plant morphologies. The species that occur most frequently include Poryphyra capensis, Aeodes orbitosa, and Notogenia stiriata [23]. These seaweeds contain sulphated galactans, which are extensively utilized biopolymers in the food industry, specifically for products like agar and carrageenan.…”

As a result of its brief lifespan, food packaging contributes significantly to environmental contamination through the rapid accumulation of plastic in the environment. In order to mitigate these impacts and provide a food packaging solution that is more environmentally sustainable, researchers have created biodegradable and biobased polymers, which are presently being introduced to the market. The current state of research regarding the incorporation of seaweed into food packaging and active packaging is summarized in this study. In order to emphasize the benefits of polysaccharides and draw attention to the constraints of current research, this study also presents a synopsis of the effects of seaweed incorporation on a range of properties, including chemical, physical, thermal, antioxidant, antimicrobial, and mechanical attributes, in addition to the release of active compounds. A multitude of polysaccharides, including those found in seaweed, have the potential to enhance the antibacterial, thermal, and mechanical properties of these polymers, among other attributes. In addition to increasing hydrophilicity and mechanical properties such as tensile strength and elongation at break, they suggest employing it as active packaging. This is feasible as a result of the antioxidant properties of seaweed, which inhibit lipid oxidation and decrease toxic, mutagenic, or carcinogenic free radicals, thereby extending the nutritional value and shelf life of food. Certain varieties of seaweed have exhibited the capacity to impede the proliferation of bacteria classified as gram-positive and gram-negative. Thus, their prospective application as antimicrobial packaging is indicated.

“…These erect fronds can have an autonomous life when fragmented and can reattach to the substrate, so vegetative propagation, through fragmentation, is a frequent method of colonisation [76]. The species has a wide distribution, occurring in Atlantic Europe [6,73,[77][78][79][80][81][82], Mediterranean Sea [83], Atlantic islands [84][85][86], Atlantic Africa [87][88][89][90], and Atlantic America [91]. Guiry also mentions populations in the Indic and Pacific oceans, namely in India, Indonesia, Korea, Vietnam, and Australia, but no published information on these locations could be found [72] (Figure 2).…”

The Red Seaweed Giant Gelidium (Gelidium corneum) for New Bio-Based Materials in a Circular Economy Framework

Gelidium corneum (Giant Gelidium or Atlantic agar) is a well-known red seaweed harvested for its high-quality agar content. Agar is a mixture of the polysaccharides used in the food industry as a gelling, thickener, clarifying, and stabilizer agent. The best agar quality is also used in the laboratory as bacteriological agar. Yet, in recent years, the species has been studied for many other applications. Examples of uses are pharmaceuticals, cosmetics, food supplements, bioremediation, biofuels, biofertilizers and biostimulants, biomaterials, and nanocrystals, among others. The use of this biomass, though, raises concerns about the sustainability of the resource, since this is not a cultivated species, being harvested in the wild. Thus, other uses of G. corneum biomass increase pressure on wild stocks already stressed due to climate change. However, in a biorefinery approach, a new trend is emerging, using waste biomass rather than harvested biomass to produce new bio-based materials. These are smart solutions that transform waste into innovative products, useful for various sectors of society while reducing the impact of biomass exploitation. The aim of this review paper, thus, is to address the current state of G. corneum biology, ecology, threats, its current uses and market, and the ongoing research on innovative proposals in a circular economy framework.

“…as we have in Ghana [5] . However, in Ghana, much attention has not been given to this industrious aquatic plant and therefore its importance has not been exploited enough to help the country economically [6] . Ralfsia expansa, Ulva flexuosa, Hydropuntia dentata, Hypnea musciformis, Lithothamnion bisporum, Ulva fasciata, Centroceras clavulatum, Ulva lactuca, Chaetomorpha linum, and Caulerpa taxifolia are the most abundant seaweed in Ghana and they all play key roles in affecting the spatial community organization [7] .…”

The study explored the potential of local Ghanaian seaweeds in producing agarose, a substitute for imported agarose, for gel electrophoresis in DNA fragment separation. Seaweeds like Gracilaria cervicornis and Hydropuntia dentata, collected from Kpone and Labadi, were processed to extract agarose using methods like polyethylene glycol, diethylaminoethyl cellulose, and dimethyl sulfoxide. These red algae showed high agar content, with Gracilaria cervicornis yielding more agarose with better gel strength and temperature properties than Hydropuntia dentata. No agar was obtained from Ulva fasciata and Caulerpa taxifolia. The study demonstrated the effectiveness of locally produced agarose in deoxyribonucleic acid separation, suggesting potential for commercial production of 'Ghanaian agarose' for molecular work.
