Summary: This study investigated eco-friendly methods for the recovery of fatty acids, phenolics, and carrageenan fractions, which are faster, produce higher yields, and can be cost-effective compared to conventional methods. Pressurized liquid extraction showed the highest antioxidant potential and total phenolic content, while microwave-assisted extraction and pressurized-water carrageenan extraction efficiently recovered the carrageenan fraction.

Summary: The study aimed to evaluate BFT effluent as a fertilizer for red seaweed cultivation and its effects on carrageenan yield and quality. Results showed that BFT effluent can replace von Stosch solution in tank cultivation of K. alvarezii, and the seaweed, along with bacteria and microalgae from the effluent, can function as an effective biofilter in IMTA systems.

Summary: Seven different bio-based ionic liquids were investigated for their ability to coagulate kappa-carrageenan, with two showing promising results in terms of polysaccharide extraction yield and properties similar to the conventional method. This coagulation method using bio-based ionic liquids may serve as a suitable alternative for eco-friendly downstream processing of carrageenophytes.

Summary: This study aimed to substitute wheat flour with K. alvarezii powder and determine its effects on the physical properties and composition of snack crackers. The results showed that the addition of K. alvarezii powder led to a decrease in color and water activity, while an increase in ash and fiber content. The protein, fat, and moisture content decreased with the addition of K. alvarezii powder.

Summary: This study optimized the regeneration of polyploidy from young thallus segments of Kappaphycus alvarezii for genetic improvement. The results showed differential response in callus proliferation and development of new thallus when Kappaphycus thallus segments were cultured on sterile sea water supplemented with different combinations of Indole acetic acid, Kinetin, and Acardian Marine Plant Extract Powder. The combination of Acardian Marine Plant Extract Powder, Indole acetic acid, and Kinetin, along with exposure to colchicine, induced the highest frequency of polyploidy regeneration from meristematic cells. Anatomical and microscopic studies provided further insights into the characteristics of colchicine-induced polyploidy.

Summary: This study evaluated the phytochemical constituents, antioxidant, and antibacterial properties of Kappaphycus alvarezii and Cymodocea serrulata. Both seaweeds contained flavonoids, tannins, phenolic compounds, glycosides, steroids, carbohydrates, and ashes. Alkaloids were only found in K. alvarezii. The chloroform extracts of both seaweeds exhibited antagonistic efficacy against Bacillus subtilis, Vibrio parahaemolyticus, Vibrio alginolyticus, Vibrio harveyi, and Klebsiella pneumoniae. GC-MS analysis revealed the presence of numerous bioactive compounds in both seaweeds, which contributed to their antioxidant and antibacterial activities. Based on the results, K. alvarezii and C. serrulata could be considered as valuable sources of nutritional and medicinal ingredients.

Summary: This study utilized red seaweed Kappaphycus alvarezii for the production of bioplastic film with optimized plasticizer to seaweed biomass ratio, resulting in a thin bioplastic film with higher tensile strength. The bioplastic film obtained from the seaweed showed better physical and mechanical properties, suggesting seaweed as a potential alternate source for bioplastic production that may reduce the usage of non-degradable plastics.

Summary: Indonesia is the largest producer of carrageenophyte seaweeds, with substantial seasonal and regional variation in production and product quality of farmed K. alvarezii. Evaluation of K. alvarezii cultured at 10 different geographic locations in Indonesia showed highly variable production and product quality data. These results can help select and evaluate better-performing K. alvarezii cultivars to improve seaweed farming productivity in Indonesia.
