The role of marine bacteria in modulating the environmental impact of heavy metals, microplastics, and pesticides: a comprehensive review
AI summary Read the abstract
This comprehensive review covers how marine bacteria mitigate environmental impacts of heavy metals, microplastics, and pesticides through processes including biosorption, biotransformation, biofilm colonization of microplastics, and enzymatic pesticide degradation.
Bacteria assume a pivotal role in mitigating environmental issues associated with heavy metals, microplastics, and pesticides. Within the domain of heavy metals, bacteria exhibit a wide range of processes for bioremediation, encompassing biosorption, bioaccumulation, and biotransformation. Toxigenic metal ions can be effectively sequestered, transformed, and immobilized, hence reducing their adverse environmental effects. Furthermore, bacteria are increasingly recognized as significant contributors to the process of biodegradation of microplastics, which are becoming increasingly prevalent as contaminants in marine environments. These microbial communities play a crucial role in the colonization, depolymerization, and assimilation processes of microplastic polymers, hence contributing to their eventual mineralization. In the realm of pesticides, bacteria play a significant role in the advancement of environmentally sustainable biopesticides and the biodegradation of synthetic pesticides, thereby mitigating their environmentally persistent nature and associated detrimental effects. Gaining a comprehensive understanding of the intricate dynamics between bacteria and anthropogenic contaminants is of paramount importance in the pursuit of technologically advanced and environmentally sustainable management approaches.

Colonization characteristics and surface effects of microplastic biofilms: Implications for environmental behavior of typical pollutants
AI summary Read the abstract
This review examines how bacteria colonize microplastic surfaces in water, forming biofilms that change how the plastics behave in the environment. These biofilms alter the surface properties of microplastics and affect how they absorb and transport heavy metals and other pollutants. Understanding biofilm formation on microplastics is important because it can make the particles more dangerous by concentrating toxic substances that could eventually enter the food chain.
Biofilm on microplastics in aqueous environment: Physicochemical properties and environmental implications
AI summary Read the abstract
This review examines how bacteria and other microorganisms form sticky films called biofilms on microplastic surfaces in water. These biofilms change how microplastics move through the environment and increase their ability to absorb pollutants like heavy metals, pesticides, and antibiotics. Biofilm-coated microplastics may also carry harmful bacteria, making them a greater potential health risk than clean microplastic particles.
