Harnessing Green Microbial Technology for Sustainable Bioremediation: Innovations and Future Directions

Abstract

Green microbial technology offers a transformative, sustainable approach to addressing the escalating challenge of environmental pollution. This chapter examines how the natural metabolic capacities of microorganisms can be harnessed for bioremediation, transforming hazardous contaminants such as petroleum hydrocarbons, heavy metals, and pesticides into less harmful compounds. Traditional degradation processes, both aerobic and anaerobic, are enhanced by modern advances in genetic engineering and synthetic biology. Customised microbial strains and engineered consortia have demonstrated improved pollutant breakdown and increased resilience under variable environmental conditions. The integration of bioaugmentation and biostimulation strategies has further boosted the efficiency of remediation efforts in both laboratory and field settings. In addition, innovative bioreactor designs and emerging microbial electrochemical systems illustrate promising avenues for combining remediation with energy recovery and real‐time process optimisation. Despite these advances, challenges persist, including environmental variability, regulatory constraints, economic feasibility, and ecological and biosafety concerns. Continued interdisciplinary research and collaboration are essential to overcome these obstacles, ensuring that green microbial technologies contribute effectively to sustainable environmental management and public health protection.
