In general terms, biological remediation refers to processes aimed to transform a contaminated environment in order to bring it back to its pristine state. Biological remediation involves by definition the use of living organisms (e.g., micro-organisms, fungi or plants) able to eliminate, reduce and contains the contamination level to meet the criteria set by legislation. The remediation of polluted environments occurs exploiting the natural ability of the organisms to counteract the presence of harsh and toxic substances, which can be either physically removed from the contaminated matrices or degraded in less harmful forms for humans and the ecosystem.
In this regard, Bactory provides consultation services about the biological remediation of soils and sediments contaminated by organic pollutants, such as hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), polycarbonyl biphenyls (PCBs) and inorganic compounds (heavy metals and semi-metals).
The consultation services offered by Bactory in this field include:
- Qualitative and quantitative analyses of the microbial communities associated with environmental matrices, such as soils, sediments, surface waters, groundwater and waste;
- Identification of microbial strains potentially applicable for the biodegradation/biotransformation of specific pollutants;
- Determination of the presence in environmental matrices contaminated by organic or inorganic substances of microbial species able to reduce the contamination level;
- Tests to evaluate the production of surfactants by biological systems;
- Tests for assessing the toxicity levels of soils contaminated by organic and inorganic compounds through the use of model plants;
- Consultation for the development of processing chains for the transformation of organic waste into compost;
- Consulting for the development of reclamation chains for the biological remediation of soils and sediments contaminated by organic and inorganic pollutants.
