Modern society is highly dependent on industrial activity. While industry provides significant benefits, it also releases a variety of pollutants into the environment. These contaminants can enter the human body through the food chain, via soil, water, plants, and animals, and may exhibit carcinogenic, teratogenic, or mutagenic properties. Their toxic effects are often cumulative. To mitigate adverse environmental and biological impacts, numerous decontamination and remediation techniques have been developed. Currently, a wide range of physical, chemical, and thermal methods are employed to separate, transform, or degrade pollutants. In comparison to these approaches, biological techniques such as bioremediation are considered more cost-effective, do not generate waste, and are often described as environmentally friendly. Bioremediation utilizes microorganisms that can survive in contaminated environments and degrade pollutants. These microorganisms use contaminants as sources of carbon and electrons for growth and reproduction. For optimal results, bioremediation procedures typically employ consortia of autochthonous microorganisms isolated directly from the contaminated site. The metabolic versatility of these microorganisms and their interactions with both organic and inorganic pollutants are most pronounced within such consortia, where two or more species co-metabolically degrade specific components. The end products of bioremediation, including carbon dioxide, water, and microbial biomass, are non-toxic, resulting in an environment that is remediated without the generation of additional waste. Bioremediation of contaminated soils is of particular importance in agriculture, as it contributes to the restoration of soil fertility, reduces the risk of toxic substances entering the food chain, and preserves the quality of agroecosystems. The application of microbial technologies represents a sustainable and environmentally friendly solution that supports safe food production and long-term environmental protection.
