Next-generation microalgae biorefinery: innovations in sustainable astaxanthin, biofuel, and aquafeed production

Microalgal Astaxanthin: From Metabolic Regulation to Industrial Biomanufacturing for a Sustainable Bioeconomy

Astaxanthin is a ketocarotenoid with potent antioxidant properties. It exhibits higher antioxidant activity than several other carotenoids and has potential applications in cosmetics, nutraceuticals, and pharmaceuticals. Microalgae are the primary producers in aquatic ecosystems. They are also regarded as sustainable a...

Microalgae-derived biodiesel as a scalable and sustainable pathway for next-generation biofuels

Microalgae-derived biodiesel is increasingly regarded as a next-generation renewable fuel because microalgae combine rapid biomass growth, high lipid productivity, carbon dioxide capture, and cultivation on non-arable land or nutrient-rich wastewater. This review critically integrates recent progress in strain improvem...

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris , its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attracti...

Cyanobacterial biorefinery: sustainable wastewater management for generation of biofuels and high-value products aligning with a circular economy approach

Microalgae for biohydrogen production: technological advancement, economic potential, and sustainable energy solutions

Microalgae are promising renewable resources for sustainable hydrogen production, offering a pathway towards carbon-neutral energy systems and supporting the Sustainable Development Goals (SDGs). Biohydrogen production occurs through hydrogenase- and nitrogenase-mediated pathways, including direct and indirect biophoto...

Sustainable biofuel production from marine macroalgae: strategic pathways for a decarbonized circular bioeconomy

Global energy demands and fossil fuel environmental impacts necessitate sustainable renewable alternatives. Seaweed (macroalgae), as a third-generation feedstock, offers a promising solution. This review evaluates the potential of seaweed-derived biofuels, including bioethanol, biogas, and biodiesel. It examines the...
