Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Background:

Persistent pesticides in agriculture pose ecological threats due to their stable chemical composition.
Biodegradation offers a cost-effective solution for reducing pesticide residues, particularly in soil environments.
Identifying efficient microbial strains is crucial for successful pesticide bioremediation.

Purpose of the Study:

To determine the most effective microbial strain for the biodegradation of pyrethroid-contaminated soil.
To apply a multi-criteria decision-making (MCDM) approach for selecting the optimal microbial strain.
To introduce the TOPSIS method for microbial strain selection in pesticide bioremediation.

Main Methods:

A decision-making system was employed to evaluate five microbial alternatives: Bacillus, Acinetobacter, Escherichia, Pseudomonas, and Fusarium.
Key criteria included pH, temperature, RPM, concentration, degradation percentage, and time required for degradation.
The TOPSIS (Technique for Order Performance by Similarity to Ideal Solution) method was utilized to rank the microbial strains based on performance against ideal parameters.

Main Results:

Acinetobacter (A2) was identified as the optimal strain for pyrethroid biodegradation, achieving the highest relative closeness value (0.740).
The ranking of microbial strains from most to least effective was: Acinetobacter, Fusarium, Bacillus, Pseudomonas, and Escherichia.
Escherichia (A3) received the least preference for pyrethroid biodegradation among the tested strains.

Conclusions:

Acinetobacter is the recommended microbial strain for efficient biodegradation of pyrethroid-contaminated soil.
The study highlights the potential of Acinetobacter, despite limited existing research, for xenobiotic compound degradation.
The application of the TOPSIS method in this context represents a novel approach to selecting microbial strains for environmental remediation.
