This adaptation enables them to thrive in contaminated environments where other microbes may struggle to survive.

The bioremediation process utilizing these adapted microbes involves several stages. Initially, the microorganisms colonize the contaminated soil, forming biofilms that enhance their stability and metabolic activities. As they proliferate, they begin to degrade the sulphanilic acid, gradually reducing its concentration in the soil matrix.

One of the key advantages of using sulphanilic acid-adapted microbes for bioremediation is their ability to operate in situ, minimizing the need for expensive and disruptive soil excavation. This approach also allows for the treatment of large areas of contaminated land with relatively low operational costs compared to traditional physical or chemical remediation methods.

Furthermore, these adapted microbes can potentially address secondary pollutants that may be present alongside sulphanilic acid. Many industrial sites contaminated with sulphanilic acid also contain other aromatic compounds, and the enzymatic versatility of these microbes may allow for simultaneous degradation of multiple contaminants.

Research has shown that certain bacterial strains, particularly those belonging to the genera Pseudomonas, Bacillus, and Rhodococcus, demonstrate significant potential for sulphanilic acid bioremediation. These microbes not only tolerate high concentrations of the pollutant but also exhibit rapid growth rates and efficient degradation kinetics.

The application of sulphanilic acid-adapted microbes in bioremediation strategies can be further enhanced through bioaugmentation techniques. This involves introducing a consortium of pre-adapted microbes to the contaminated site, potentially accelerating the remediation process and improving overall efficiency.

While the bioremediation potential of these microbes is promising, it is essential to consider potential ecological impacts. Introducing non-native microbial populations may affect the local microbial community structure and function. Therefore, careful monitoring and assessment of long-term ecological effects are crucial components of any bioremediation strategy employing sulphanilic acid-adapted microbes.
