Biodegradation of phenol and its derivatives by engineered bacteria: current knowledge and perspectives

Original language description

Biodegradation of phenolic compounds is a promising alternative to physical and chemical methods used to remove these toxic pollutants from the environment. The ability of various microorganisms to metabolize phenol and its derivatives (alkylphenols, nitrophenols and halogenated derivatives) has therefore been intensively studied. Knowledge of the enzymes catalyzing the individual reactions, the genes encoding these enzymes and the regulatory mechanisms involved in the expression of the respective genes in bacteria serves as a basis for the development of more efficient degraders of phenols via genetic engineering methods. Engineered bacteria which efficiently degrade phenolic compounds were constructed in laboratories using various approaches such as cloning the catabolic genes in multicopy plasmids, the introduction of heterologous genes or broadening the substrate range of key enzymes by mutagenesis. Efforts to apply the engineered strains in in situ bioremediation are problematic, since engineered strains often do not compete successfully with indigenous microorganisms. New efficient degraders of phenolic compounds may be obtained by complex approaches at the organism level, such as genome shuffling or adaptive evolution. The application of these engineered bacteria for bioremediation will require even more complex analysis of both the biological characteristics of the degraders and the physico-chemical conditions at the polluted sites.
