Abstract: (89 Views) |
Brown seaweeds (Phaeophyceae) represent a vast and underutilized marine biomass, thriving in coastal ecosystems all over the world, including the coasts of the Oman Sea and Sistan and Baluchestan Province. Their unique biochemical composition, rich in polysaccharides (alginate, fucoidan, laminarin), polyphenols (phlorotannins), and minerals, positions them as a highly promising feedstock for the burgeoning field of marine biotechnology. This review synthesizes recent advancements in the biotechnology of brown algae, moving beyond traditional extraction methods to explore cutting-edge applications. We detail the development and optimization of enzymatic and microbial-based processes for the efficient saccharification and fermentation of algal biomass into high-value products, including biofuels (bioethanol, biobutanol), biochemicals (organic acids, pigments), and nutraceuticals. Furthermore, we highlight the innovative use of genetic and metabolic engineering tools to enhance seaweed cultivation, tailor composition, and create sustainable bioprocessing pipelines. The integration of brown seaweed into a circular bioeconomy model, addressing challenges and future perspectives, is also discussed. The following is an example model that justifies the use of brown algae extract in feeding sea cucumber larval stages. |
