Improvement of Bioremediation Efficiency on the Gene Level

M. Česnik, Z. Findrik Blažević and M. Vuković Domanovac


Bioremediation uses the potential of microorganisms for the removal of contaminants from the environment. The metabolic pathways that degrade contaminants into less toxic substances are very complex. Bioremediation mechanisms are studied on the gene level using advanced molecular biology techniques. The gene responsible for the production of a protein that degrades the contaminant can be isolated and introduced into another organism, creating an organism with enhanced bioremediation properties. Scientific research worldwide focuses on genetically engineered microorganisms. However, the greatest obstacle in their application for bioremediation is the legal framework and insufficient knowledge of the consequences of their release into the environment.
