According to the United Nations Environment Programme (UNEP), soil health is declining over the decades and it has an adverse impact on human health and food security. Hence, soil health restoration is a need of the hour. It is known that microorganisms play a vital role in remediation of soil pollutants like heavy metals, pesticides, hydrocarbons, etc. However, the indigenous microbes have a limited capacity to degrade these pollutants and it will be a slow process. Genetically modified organisms (GMOs) can catalyze the degradation process as their altered metabolic pathways lead to hypersecretions of various biomolecules that favor the bioremediation process. This review provides an overview on the application of bioengineered microorganisms for the restoration of soil health by degradation of various pollutants. It also sheds light on the challenges of using GMOs in environmental application as their introduction may affect the normal microbial community in soil. Since soil health also refers to the potential of native organisms to survive, the possible changes in the native microbial community with the introduction of GMOs are also discussed. Finally, the future prospects of using bioengineered microorganisms in environmental engineering applications to make the soil fertile and healthy have been deciphered. With the alarming rates of soil health loss, the treatment of soil and soil health restoration need to be fastened to a greater pace and the combinatorial efforts unifying GMOs, plant growth-promoting rhizobacteria, and other soil amendments will provide an effective solution to soil heath restoration ten years ahead.

“…The first large-scale application of bioremediation occurred in 1972, when it was executed to clean up an oil spill by Sun Oil Pipeline Company in Ambler, Pennsylvania. Therefore, nuclear bioremediation may be considered as a technique that uses natural or genetically modified biological agents, e.g., microorganisms and plants, to catalyse the reaction of radioactive materials or radionuclides to break them down into simpler forms, thereby decreasing their half-life period or stabilising the unstable nuclear atoms (Vandana et al, 2021).…”

“…On the other side, due to the additional cost of excavation, ex-situ operations were considered relatively expensive in comparison to the in-situ approaches. Selection of a suitable bioremediation technology that efficiently can reduce the concentration of pollutants to an permissible condition is therefore critical for success of a bioremediation project (Azubuike et al, 2016;Vandana et al, 2021).…”

The extent of the pollution, produced by the rapid release of radionuclides into environment, has prompted public and scientific concern in last few decades. Their removal is a challenge for scientists as, like other contaminants, they cannot be purified and reintroduced into the environment in a short time period. The perceived high environmental and economic costs of invasive physicochemical degradation, technologies are emerging for bioremediation of nuclear waste. The basis of these approaches is the efficient usage of radioactive elements and fission products via natural nutrition cycles. Sequestrants, siderophores, cytochromes, organic acids, and hydrogenase complexes have all been shown to be effective in the degradation pathways. Recent advances have been made in comprehending microbial colonisation. Several discoveries are on record for understanding the metal-microbial interactions in radioactive habitats as well as the biological foundation of radioactive waste conversion in these situations. In-depth investigations have shown the positive results in this domain. This review presents a quick overview of nuclear energy and waste creation, followed by applications, health impacts, nuclear waste management, and the significance of microbial radioactive waste breakdown.

This chapter examines how synthetic cell-free processes, bioremediation, and biomass usage interact to promote sustainability and innovation. It emphasises biomass's potential as a source of renewable energy and for the generation of biofuels, concentrating on a variety of feedstocks and cutting-edge conversion methods. While synthetic cell-free methods offer customised biochemical reactions beyond biological cells, bioremediation employs microorganisms to reduce pollution. The chapter investigates how various disciplines might be combined to address environmental problems, emphasising moral questions, legal issues, and practical applications. The chapter seeks to shed light on a sustainable and peaceful future through case studies and technological breakthroughs. IoT-AI system streamlines biofuel production, bioremediation, and synthetic cell-free processes for efficient workflow.
