Optimization of the rope seeding method and biochemical characterization of the brown seaweed Asperococcus ensiformis

Artificial Seaweed Reefs That Support the Establishment of Submerged Aquatic Vegetation Beds and Facilitate Ocean Macroalgal Afforestation: A Review

“…Spore transplantation employs spore dispersal, spore-bag, and rope-seeding techniques [321][322][323]. For example, spores can be delivered by attaching mesh bags of fertile sporophylls to the bottom [206]; additionally, microscopic stages can be grown in the laboratory and dispersed over the bottom.…”

“…Vegetative transplantation uses either young or old plants and either threads, gravel bags, or concrete blocks [321][322][323]. Vegetative transplantation is used to grow small sporophytes (<1 cm in height) on artificial substrata in the laboratory; the substrata are then placed in the field [330] or used to transplant much larger juvenile and adult sporophytes that are less sensitive to bottom conditions.…”

Prospects of dietary seaweeds and their bioactive compounds in sustainable poultry production systems: A symphony of good things?

“…Various seaweed species have attracted extensive research attention from biomedicine to agri-food industries as putative sources of multiple biologically active compounds such as proteins, glycoprotein, minerals, vitamins, essential fatty acids, fucoidan, carotenoids, peptides, dietary fibers, oxylipins, violaxanthin, steroids, zeaxanthin, phlorotannins, lutein, fucoxanthin, and laminarin (Venkatesan et al, 2019). Due to the presence of these bioactive compounds, there has been growing interest from researchers to use seaweeds for various applications in medicine, cosmetics, biofuel, and fertilizermanufacturing industries (Poza et al, 2022). Indeed, these bioactive compounds have functional benefits with antioxidant, antimicrobial, hypoglycemic, antiradiation, immunomodulatory, anti-inflammatory, anticancer, growth-stimulating, meatboosting, and health-promoting properties (Wang et al, 2019).…”

“…Unfortunately, harvesting beach-cast seaweeds has the unintended consequence of removing between 100 and 400 m 3 of sand per harvesting season, thus increasing erosion and changing the topography of beaches (Hyndes et al, 2021). In South Africa, commercially harvested beach-cast seaweed is mainly used for human consumption and in nutraceutical, cosmetic, and fucoidanprocessing industries (Poza et al, 2022). For seaweeds that are not beach-cast, harvesting traditionally involves cutting fronds during the low tide using boats.…”

Optimization of Alginate Extraction From Dictyota Mertensii From a Central Composite Design Associated With Response Surface Methodology: Characterization and Antioxidant Potential

“…Carbohydrates are the main components of the cell wall of brown algae, reaching up to 45 % of the dry weight of the algae. The composition of the algae in this study was compared to that of other brown algae already studied, such as Dictyota dichotoma (18.78 % residual moisture, 31.78 % ash, 14.5 % protein, 18.93 % lipids, 3.66 % fiber, and 12.35 % carbohydrate)(Imran et al 2023), and the Asperococcus ensiformis (41.18 % ash, 2.90 % protein, and 6.45 % carbohydrate)(Poza et al 2022). Meng et al(Meng et al 2022) carried out a study with 12 brown algae commercially available in the Chinese market and verified the variation in composition in the order of 14.59 -64.30 % for ash content, 4.68 -13.77 % for fiber content crude, 0.35 -4.72 % for lipid contents, 5.16 -28.19 % for protein contents.…”
