The biotechnological potential of microalgae and macroalgae across various industrial sectors is widely recognized and extensively studied. As photosynthetic organisms capable of producing high concentrations of O₂, algae offer significant advantages, such as lower production costs and reduced space requirements for cultivation, contributing to the overall cost-effectiveness of bioproducts. The bioactive compounds derived from algae have diverse applications worldwide, including nutraceuticals, human and animal nutrition, pigments, biofuels, and other industries. The growing demand for sustainable production alternatives with minimal environmental impact and reliance on clean energy has intensified research efforts into algae-based products. As a result, the use of algal biomass has been widely explored to fully leverage its properties, reduce production costs, and develop high-quality nutritional products, such as food supplements for humans and animals. Additionally, algae-derived products with high added value, such as pigments, oils, and thickeners, along with coproducts like bio-oil, biodiesel, bioethanol, and biofertilizers, have gained significant attention. The market for algae-based products is valued between US$ 12 and 30 billion and is expected to grow even further in the coming years. In this context, optimizing cultivation conditions and minimizing process costs are key research areas aimed at enhancing the production of high-quality functional bioproducts, particularly in the biofuels industry.
