Abstract
Bioremediation is a novel and, environmentally benign technology that employs biological microbes to reduce pollution. Waterborne contaminants are a group of common materials that can enter rivers through a variety of entrance points, such as wastewater, the surrounding environment, ship emissions, and other sources. The majority of these dangerous compounds are consumed by marine life, whereupon they bioaccumulate in their body tissues and spread along the food chain through a process known as biomagnification. These practices may adversely affect the physiological processes of organisms, and the biochemical systems present in organic environments, which may have unintended negative effects concerning the overall wellness of humans, and animals, alongside the natural world. This review delves into various hazardous materials including a broad variety of chemical pollutants: including heavy metals, pesticides, and microplastics. Given the harmful consequences these toxins exert on environmental integrity, human health, and financial stability, immediate remediation is necessary. This review article provides a comprehensive analysis of bioremediation techniques used to address contamination of both soil and, water, emphasizing the intricate relationships between populations of microbes, environmental variables, and remediation efficacy. Therefore, various bioremediation methodologies are illustrated focusing on employing microbes in the procedure and investigating various technologies implemented. Furthermore, the metagenomic approach's potential to improve the effectiveness of bioremediation was highlighted. Ultimately, it highlights the necessity of bioremediation as an answer to organic contamination of soil and presents an overview of the various strategies and technologies accessible. The importance of this review is to deal with the cause of pollution (hazardous materials) and the solution (bioremediation). The goal and originality of this review are to provide the scientific community with an understanding and resolution to this global concern. Bioremediation will become increasingly important in the coming century due to global warming, increased mass production, and population growth.
