MICROALGAS: UMA ESTRATÉGIA SUSTENTÁVEL NA TRANSFORMAÇÃO E OBTENÇÃO DE COMPOSTOS ORGÂNICOS

MICROALGAE: A SUSTAINABLE STRATEGY IN THE TRANSFORMATION AND OBTAINING OF ORGANIC COMPOUNDS

The present review presents the biotechnological potential of microalgae, highlighting its applications in biofuels, bioremediation, production of bioactive compounds, biocatalysts, and biofertilizers. Microalgae are photosynthetic microorganisms that combine characteristics of plants and heterotrophic microorganisms, such as yeasts, bacteria, and fungi. They can be considered biotechnological agents of extreme versatility and metabolic adaptability. Its photosynthetic efficiency can absorb large volumes of anthropogenic CO₂ and convert it into biomass rich in compounds of high biological and energetic value, enabling the development of sustainable bioremediation processes and the production of third-generation biofuels and biofertilizers. In addition, its biomass has aroused interest in obtaining compounds with biological action, such as carotenoids, mycosporine-like amino acids, polyunsaturated fatty acids, sterols, phycocolloids, carbohydrates, and proteins. The biotechnological potential of microalgae does not end with the production and extraction of its biomass. Its dynamic and adaptive metabolism allows its use in the biotransformation of xenobiotic substrates and the production of compounds of chemical and pharmaceutical interest. In this perspective, microalgae have application qualities as a biotechnological platform in developing synergistic processes between the environment, society, and industry, thus contributing to the expansion and use of Green Chemistry and strengthening the circular economy.
