Bioremediation of Toxic Pollutants
Summary
This paper is not relevant to microplastics research — it is a broad review of bioremediation approaches for environmental pollutants including heavy metals and textile dyes, with no specific focus on microplastics.
In recent times, environment is getting gravely polluted due to increase in anthropogenic activities. Various industrial and municipal solid wastes have been a major source of heavy metal contamination in soil, water and also as atmospheric aerosols in air. Dyes from the textile industries cause water pollution which is raising a severe concern worldwide. Moreover, microplastics, organic pollutants, pharmaceutical wastes comprise various emerging toxic pollutants for the environment. These contaminants are harmful for living beings and cause various health hazards to them. Proper management of wastes from these sources is required along with environment-friendly remedial techniques. Phytoremediation has been used in this regard for many years. However, nowadays, novel biotechnological tools are used for achieving paths in bioremediation through microorganisms. Microbes possess the ability to biotransform, biosorb, and biomineralize pollutants. Various techniques are available to identify the microorganisms and study of their biological functions using for remediation of hazardous pollutants from the environment. In these chapter bioremediation of some common toxic pollutants and some of the emerging ones have been discussed.

Advancements in Biomonitoring and Remediation Treatments of Pollutants in Aquatic Environments, 2nd Edition
Not relevant to microplastics — this is an editorial introduction to a special journal issue on biomonitoring and bioremediation of aquatic pollutants broadly, covering toxic chemicals, heavy metals, and biological contaminants rather than focusing specifically on microplastics research.
Challenges and opportunities in bioremediation of micro-nano plastics: A review.
This review examines biological approaches to removing micro- and nanoplastics from the environment, focusing on microbial degradation and bioremediation strategies. While bioremediation holds promise, challenges remain in identifying microbes capable of degrading common plastic types and scaling these processes for practical environmental cleanup.
Microbial synergies in phytoremediation: A comprehensive review
Not relevant to microplastics — this is a review of how soil microorganisms (bacteria, fungi) assist plants in removing pollutants like heavy metals and hydrocarbons through phytoremediation; while the study addresses environmental contamination broadly, it does not examine microplastic pollution or its effects.
The application of bioremediation in wastewater treatment plants for microplastics removal: a practical perspective
This review assessed strategies for incorporating bioremediation into wastewater treatment plants specifically targeting microplastic removal, including bioaugmentation with microplastic-degrading microorganisms. The authors identified potential in using biofilm reactors and enhanced biological treatment but noted that microbial degradation of common polymers in wastewater timeframes remains limited.
