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

This study explores the mixotrophic cultivation of Limnospira platensis using dairy byproducts, specifically scotta whey (SW), buttermilk wastewater (BMW), and (DWW), to promote biomass production enhance composition bioactive compounds. By assessing various concentrations (1%, 2%, 4% v v−1) these byproducts in a modified growth medium, this aims evaluate their effect on L. growth, phycocyanin (C-PC) content, fatty acid methyl ester (FAME) profiles. The results show that optimal was achieved with 2% wastewater, reaching maximum 3.30 g L−1 3.19 L−1, respectively. Mixotrophic led increased C-PC yields, especially treatments, highlighting potential for producing valuable pigments. Additionally, FAME profiles indicated minimal changes compared control, oleic γ-linolenic acids being dominant conditions. These findings support viability utilizing sustainable cultivation, contributing circular bioeconomy while compounds nutritional commercial interest.
