dc.description.abstractThe marine red alga Phycocalidia vietnamensis with healthy thalli (HT) at a mature stage, moderately bleached thalli (MBT) at 5 weeks post-maturity, and fully bleached thalli (FBT) at 7 weeks post-maturity were collected from wild stocks. All samples were analyzed for biochemical such as pigments (R-phycoerythrin (R-PE), R-phycocyanin (R-PC), and chlorophyll-a), total phenolic content (TPC), antioxidants (FRAP, DPPH), moisture, lipid, protein, and carbohydrate contents. Sulfated polysaccharides and cellulose were also extracted from all the samples. Results indicated a significant reduction in all the components studied except for moisture and carbohydrates in post-maturation MBT and FBT samples over the HT. The carbohydrate was found unaffected and got densified due to the loss of other components in the thallus. Polysaccharides and cellulose contents in FBT and MBT were significantly higher than in HT. The findings suggests that the biomass harvested from wild stock after 5 weeks from maturity (MBT) could be utilized for diet purposes, while the biomass harvested after 7 weeks from maturity (FBT) could be used for the extraction of sulfated polysaccharide and cellulose for various commercial applications. Thus, the harvesting of P. vietnamensis from natural stock in post-maturation stages could provide biomass for edible and commercial applications without negatively impacting the species diversity and population structure
