Advances in Chemotactic and Non-chemotactic Bioremediation of Water: A Comprehensive Review
Summary
This review surveys both conventional and microbial-based approaches for cleaning up water contaminated by industrial and agricultural pollutants. Bioremediation is highlighted as the most eco-friendly option, using bacteria and other microorganisms to break down a wide range of waste types including plastics, heavy metals, and organic chemicals. The review identifies remaining challenges and promising directions for scaling up bioremediation in real-world applications.
Pollution has reached to a critical threshold affecting the climate and diversity of the planet Earth. All global authorities have included pollution control in their agenda for near future. Most of the environmental research nowadays is focused on removing waste generated by anthropogenic activities, may it be solid, liquid or gaseous waste. Bioremediation is believed to be the most eco-friendly approach for reducing or removing pollutants contaminating different matrices of the environment. There are various methods covered under the umbrella term of bioremediation. Chemotaxis-mediated bioremediation attracted attention of several research groups since early decade of twenty first century due to improved efficiency achieved by this strategy. There is very limited literature available on comparative account of non-chemotactic and chemotactic bioremediation. In this review, authors have extensively discussed about research developments in non-chemotactic and chemotaxis mediated bioremediation comparing the efficiency and scale of the processes.

Bioremediation Techniques for Water and Soil Pollution: Review
This review covers bioremediation techniques that use microorganisms to break down pollutants in water and soil, including microplastics, heavy metals, and pharmaceutical residues. Researchers highlight how bacteria, fungi, and algae can be harnessed to degrade plastic waste and other contaminants through natural biological processes. The study suggests that bioremediation offers a promising, environmentally friendly approach to tackling pollution, though more research is needed to optimize these techniques for real-world application.
Eco‐Friendly Solutions to Emerging Contaminants: Unveiling the Potential of Bioremediation in Tackling Microplastic Pollution in Water
This review examines bioremediation -- using microorganisms to break down microplastics in water -- as a greener alternative to costly physical and chemical removal methods. While certain bacteria and fungi show real promise in degrading plastics like polyethylene and polystyrene, challenges remain in scaling these approaches. Reducing microplastics in water is important because contaminated water is one of the main ways these particles reach humans.
Bioremediation to Overcome Microplastic Contamination in The Water Environment
This review examines how living organisms such as bacteria, algae, and worms can be used to break down and remove microplastics from water environments. Researchers evaluated evidence from 23 studies and found that bioremediation shows promise as a sustainable, low-cost approach to addressing microplastic contamination. The study identifies the key factors that influence how well these biological methods work and the challenges that remain before they can be widely deployed.
Microplastics on the frontline: causes, strategies to combat pollution and protect health with advanced bioremediation—a review
This systematic review examines how microplastics carry toxic chemicals like heavy metals and persistent pollutants into the food chain, ultimately reaching humans. It also explores promising bioremediation approaches — using bacteria and enzymes to break down microplastics — as a potential strategy to reduce exposure.
Bioremediation of Microplastics by Microorganisms: Trends, Challenges, and Perspectives
This review examines how microorganisms can be used to break down microplastic pollution in water and soil through bioremediation, a process considered more environmentally friendly than chemical alternatives. Researchers summarized the various microbial mechanisms involved, including enzymatic degradation and biofilm formation on plastic surfaces. While the approach shows promise as a green solution, the study notes that significant challenges remain in scaling these methods for real-world environmental cleanup.
