Abstract
In modern agriculture, the widespread use of organophosphorus pesticides results in environmental pollution and pose severe threats to human, flora and fauna. Hence, the efficient removal of these pesticides from polluted environment remains an enduring inspiration. Bioremediation can be used as a proficient detoxifying strategy for polluted ecosystem since it can breakdown or convert toxic pollutants into less hazardous by-products while also being cost-effective, extremely efficient, and environmental sustainable. Further, a detailed analysis of the plant growth-promoting activity of plant–bacteria relationships could be used to promote sustainable agricultural output as well as the remediation of pesticide-polluted soil and water. Hence, a bacterial strain PDB1 was extracted from the soil sample exposed to pesticide for an extended period of time at Karur district, Tamilnadu, India for the bioremediation. Using morphological, biochemical, and 16S rRNA gene analysis, the bacterium PDB1 was characterized as Bacillus substilis. The impact of Bacillus substilis on several plant - growth indices was studied in the presence and absence of the pesticide profenofos. The capacity of Bacillus substilis to degrade profenofos (PF) was examined using gas chromatography-mass spectroscopy (GC-MS). Since this isolated bacterial strain has (PF) degrading capacity as well as other characteristics that promote plant growth, the isolate could be an attractive opportunity for the advancement of bioremediation technique.
