Water, covering three-quarters of the Earth, is crucial for life and ecosystems and is also essential in industrial processes. However, most aquatic environments are polluted due to the massive discharge of wastewater with high pollutant loads, which threatens ecosystem health. To mitigate this environmental impact, humans have tried various physical and chemical strategies, but increased wastewater and reagents have the disadvantage of generating more waste, making it an environmentally unsustainable problem. Governments are now focusing on integrating living organisms or biological treatments to reduce or mitigate pollutants in contaminated matrices. Microbial biodiversity is being studied through bioprospecting strategies and the search for new microorganisms capable of biodegrading pollutants. Extremophilic microbes, which have undergone evolutionary processes and exhibited adaptive traits, have the potential to transform harmful contaminants into beneficial resources and improve their tolerance mechanisms to complex pollutants. This chapter aims to provide updated information on sustainable wastewater bioremediation processes using extremophilic microorganisms and their enzymes, considering their properties, characteristics, stability, and biodegradation capacity. Genetic modifications and editions are also discussed to obtain biomolecules with greater versatility and efficacy

The latest technological advances in the current era have allowed development in the different areas and disciplines of science, leading to a series of discoveries that enhance current scientific knowledge. These advances are largely due to the rapid evolution in the manufacture of increasingly sophisticated electronic devices. However, the consumption and disposal of electronic devices generate environmental pollution problems (e-waste) in different matrices of the ecosystem, linked to an accelerated demographic growth. A variety of techniques have been used to reduce the outcome of e-waste. Bioremediation is an environmental and eco-friendly strategy based on the use of the metabolic capabilities of organisms and microorganisms. For a better application of these environmental strategies, the application of molecular strategies is proposed under a multiomic approach, which involves the global and integrated study of the molecular components resulting from the interaction of organisms and microorganisms with waste products. Therefore, the aim of this chapter is to provide details on the microbes that degrade electronic waste (e-waste) and their study under a multiomic perspective (genomics, transcriptomics, metabolomics, and proteomics).
