Complex anti-corrosion coatings using bacterial cells


Biologically based manufacturing could contribute significantly to the development of an energy-efficient anti-corrosion coating deposition treatment on metal substrates. The today's conventional galvanic processes are only 40-50% efficient. The main reason is the low metal complex load capacity (milk) of the galvanic bath. It is known from the biotechnology processing that bioreactors including cell factories are very efficient in both product output and in energy consumption. From metal complex waste and treatment by cell factories high yields-yields are already used. Consequently metabolic processes could have far more metal complex load capacity, which is an opportunity for this industrial process. In principle, biological containment of live bacterial cell is far more accurate because of the ease of control of the surface reactions. The aim of the project is to develop a continues bioreactor process in which the metal substrates will be treated with a metal-complex, deposit by Genetically Engineered Micro-organism (Gems). The substrate is running in a safety, closed system. Nonliving cells will be coming out of the after treatment step and the metal-complex will be properly cured.
