Breakthrough study identifies bacteria capable of removing toxic pollutants while enriching soil with essential nutrients.
New Delhi, January 2: Researchers from the Indian Institute of Technology (IIT) Bombay have made a groundbreaking discovery by identifying bacteria capable of consuming toxic pollutants in soil and transforming them into useful nutrients that promote plant growth, according to an official release.
The findings, published in the journal Environmental Technology and Innovation, highlight the potential of specific bacterial species to degrade harmful pollutants, improve soil fertility, and enhance plant health naturally.
Pollutant Breakdown and Nutrient Production
The identified bacteria, primarily from the Pseudomonas and Acinetobacter genera, are adept at breaking down aromatic compounds—a group of toxic chemicals found in pesticides, herbicides, and industrial waste. These compounds can inhibit seed germination, reduce crop yield, and accumulate in plant tissues, posing significant challenges to the agriculture sector.
“These bacteria feed on pollutants, breaking them down into simpler, harmless, non-toxic compounds. In this way, they act as natural cleaners of polluted environments,” explained Prof. Prashant Phale from the Department of Biosciences and Bioengineering at IIT Bombay, who guided the research conducted by Sandesh Papade as part of his PhD study.
Advantages Over Traditional Methods
Traditional approaches to soil decontamination, such as chemical treatments and soil removal, are often costly and incomplete. In contrast, these naturally occurring bacteria offer a sustainable and cost-effective alternative for soil remediation.
In addition to breaking down harmful chemicals, these bacteria also:
- Boost plant growth hormones
- Inhibit the growth of harmful fungi
- Make essential nutrients readily available to plants
Impact on Agriculture and Environment
The study suggests that the use of such bacteria could reduce reliance on chemical fertilizers and pesticides, paving the way for healthier crops and sustainable farming practices.
By harnessing the natural abilities of these bacteria, the agriculture industry can address soil contamination, improve crop yield, and support a more eco-friendly approach to farming.
This discovery is expected to have a far-reaching impact on both agriculture and environmental conservation, offering a natural solution to a persistent problem.
