Abstract Extensive anthropogenic activity has led to the accumulation of organic and inorganic contaminants in diverse ecosystems, which presents significant challenges for environment its inhabitants. Utilizing microalgae as a bioremediation tool can present potential solution these challenges. Microalgae have gained attention promising biotechnological detoxifying environmental pollutants. This is due their advantages, such rapid growth rate, cost-effectiveness, high oil-rich biomass production, ease implementation. Moreover, microalgae-based remediation more environmentally sustainable not generating additional waste sludge, capturing atmospheric CO 2 , being efficient nutrient recycling algal production biofuels high-value-added products generation. Hence, achieve sustainability's three main pillars (environmental, economic, social). Microalgal mediate contaminated wastewater effectively through accumulation, adsorption, metabolism. These mechanisms enable reduce concentration heavy metals levels that are considered non-toxic. However, several factors, microalgal strain, cultivation technique, type pollutants, limit understanding removal mechanism efficiency. Furthermore, adopting novel technological advancements (e.g., nanotechnology) may serve viable approach address challenge refractory pollutants process sustainability. Therefore, this review discusses ability different species mitigate persistent industrial effluents, dyes, pesticides, pharmaceuticals. Also, paper provided insight into nanomaterials, nanoparticles, nanoparticle-based biosensors from immobilization on nanomaterials enhance open new avenue future advancing research regarding biodegradation

Carotenoids constitute compounds of significant biological interest due to their multiple activities, such as antimicrobial, anticancer, antiadipogenic, antidiabetic, and antioxidant properties. Metabolic syndrome (MetS) comprehends a series metabolic abnormalities (e.g., hypertension, obesity, atherogenic dyslipidemia) that can affect children, adolescents, the elderly. The treatment MetS involves numerous medications, which, despite efficacy, pose challenges prolonged use, high costs, various side effects. derivatives have been proposed alternative treatments because they reduce serum triglyceride concentrations, promote insulin response, inhibit adipogenesis, downregulate angiotensin-converting enzyme activity. However, carotenoids are notably sensitive pH, light exposure, temperature. This review addresses activity lycopene, lutein, fucoxanthin, astaxanthin, crocin, β-carotene towards MetS. It includes discussion sources, extraction methods, characterization techniques for analyzing carotenoids. Encapsulation approaches critically reviewed alternatives prevent degradation improve performance A brief overview physiopathology epidemiology diseases, including MetS, is also provided.
