Advances and emerging perspectives in arsenic bioremediation: a review study on mechanisms and innovations.

Phytoremediation
Arsenic leaching from soil into groundwater ends up in irrigation water, quietly accumulating in garden vegetables and the rice you rinse before cooking — and these bacterial cleanup methods could one day protect both your local watershed and your raised beds.
Arsenic is a naturally occurring poison that contaminates groundwater in many parts of the world, largely because of mining, agriculture, and industrial activity. Scientists have been studying specific bacteria that can grab arsenic out of water and neutralize it, with some strains removing over 94% of the contamination. This review maps out how those bacteria work and explores how we might deploy them at a large scale to clean up polluted water supplies — and even recover arsenic for industrial reuse instead of letting it stay in the environment.
Key Findings
Bacterial strains Alishewanella agri and Bacillus cereus achieved arsenic removal rates exceeding 94% through redox transformation processes.
A circular economy framework could convert arsenic from a hazardous pollutant into a recoverable industrial resource, reducing waste and cost.
A key challenge identified is the 'scaling gap' — lab results do not yet translate reliably to real-world field conditions, with 2025–2026 modeling databases being developed to bridge this divide.

Researchers reviewed cutting-edge biological methods for removing arsenic — a toxic element poisoning drinking water for over 200 million people worldwide — and found that certain bacteria can eliminate more than 94% of arsenic contamination, pointing toward scalable, eco-friendly cleanup solutions.
Abstract Preview
Arsenic (As) contamination remains an ongoing public health crisis, impacting over 200 million people due to both natural processes and human activities that disperse the toxic element. Traditional...
