Environmental Impact of Xenobiotic Aromatic Compounds and Their Biodegradation Potential in Comamonas testosteroni

Summary

This review examines how aromatic compounds found in plastics, pesticides, and antibiotics pollute our environment and how bacteria like Comamonas testosteroni can break them down naturally. The research shows that microplastics are accumulating in oceans and wildlife, causing health problems ranging from physical damage to disruption of metabolism and development. Scientists are exploring ways to use these bacteria and microbiome engineering to create biological cleaning systems that could sustainably treat pollution without adding more chemicals to the environment.

Background

Xenobiotic aromatic compounds are widely used in modern life as raw materials for plastics, pesticides, and antibiotics. Their increased production and consumption have led to significant environmental pollution. Some microorganisms like Comamonas testosteroni can utilize these pollutants as substrates for growth, offering potential for bioremediation technology.

Objective

To review the environmental impact of common xenobiotic aromatic compounds and their biodegradation strategies by Comamonas testosteroni. The study examines biodegradation pathways, key functional genes and enzymes, and regulatory mechanisms while proposing microbiome engineering approaches for improved bioremediation.

Results

C. testosteroni can degrade aromatic compounds through multiple pathways including ortho and meta cleavage of protocatechuic acid, CoA-dependent epoxide pathway, and other mechanisms. Key functional genes include phtA, phtB, and the pmd operon. Environmental data show microplastic pollution levels reaching 6,701,375 items/m² on some beaches and pesticide-induced developmental defects in exposed organisms.

Conclusion

Microbial biodegradation through organisms like C. testosteroni offers a sustainable solution for treating xenobiotic aromatic compound pollution. Future approaches should employ multi-omics technology and microbiome engineering to construct biofilm-based biodegradation systems for improved aromatic compound bioremediation in contaminated environments.
