    Chapter 15 - Recent trends for treatment of environmental contaminants in wastewater: an integrated valorization of industrial wastewater
    (Elsevier, 2022) Hualpa-Cutipa, Edwin; Solórzano Acosta, Richard Andi; Sangay-Tucto, Sheena; Mendoza Beingolea, Xiomara Gisela; Talavera Gutiérrez, Gianfranco; Navarro Zabarburú, Isabel
    Industrial wastewater generation is a matter of global concern, due to pollutants containing and their releasing representing a risk to the health of ecosystems. Industries such as mining, pharmaceutical, textile, agroindustry, plastics industry, among others, generate large amounts of effluents containing hazardous pollutants which have a negative impact on the environment. Heavy metals, organic pollutants, dyes, microplastics (MPs) and nano-plastics (NPs) have been found in wastewater proceeding from industries. These pollutants require complex processes for removal from water bodies. To remove or reduce these hazardous pollutants from wastewater, several strategies have been proposed, including physical, chemical, biological (biotechnological) aimed at reducing the concentration of these pollutants. This chapter discusses the several techniques for removal pollutants from wastewater and highlights approaches based on the integration of physicochemical-biotechnological techniques applied to remove pollutants from wastewater produced by different industries, which would allow improving the process efficiency of pollutant removal and treatment in wastewater generated by these industries.

    Chapter 7 - Omics approaches for microalgal remediation of wastewater
    (Crc Press, 2022) Hualpa-Cutipa, Edwin; Solórzano Acosta, Richard Andi; Mendoza Beingolea, Xiomara Gisela; Maldonado Jimenez, Ingrid; Yana-Neira, Evelin; Navarro Zabarburú, Isabel
    Environmental pollution is a growing issue, and ecosystems such as forests, grasslands, wetlands, rivers, seas, lakes, and lagoons are worsening due to the arrival of pollutants that harm the fauna and flora present. Aquatic ecosystems, which receive many polluted effluents from domestic, industrial, and storm wastewater, are one of the ecosystems with the greatest impact. A series of chemical, physical, and biological solutions for the treatment and recycling of these heterogeneous effluents with high loads of organic and inorganic compounds have been developed through an attempt to mitigate the negative impact produced by wastewater. Biological components have an advantage over other strategies in the treatment of polluted environments. Such a biologic group includes bacteria, fungi, plants, algae, and microalgae, which all could treat and recycle wastewater. Previous experiences in the use and application of microalgae in the treatment of contaminated environments have successfully been carried out, showing the great potential of microorganisms, in addition to their innate capacity to produce carbon and fix CO2, production of antimicrobial compounds, production of biofuels, among others. The use of molecular tools has allowed the study of different molecular processes, and the integration of omics techniques (genomics, transcriptomics, proteomics, metabolomics, etc.) has improved our understanding of different complex mechanisms of these autotrophic microorganisms. In addition, each omics strategy contributes in a particular way to understanding the specific complex mechanisms that govern the growth, development, and response of microalgae to different stressors. This chapter aims to highlight the application of omics strategies in the study of microalgae with potential in the treatment and recycling of domestic, industrial, and storm wastewater, as well as the integration of these omics to generate global application platforms for the understanding of molecular behavior in the biological processes of microalgae.
