Petra previously studied at the Institute of Chemical Technology in Prague and graduated with a masters degree in Biotechnology and Bioengineering. Her experimental work was mostly focused on biofilm development of bacterium Rhodococcus erythropolis, a potent degrader of organic contaminants.
Some microorganisms have the ability to exchange electrons with solid materials. This unique feature of bacteria can be used to electrochemically enhance in situ bioremediation of organic pollutants in groundwater. Electrodes inserted under the ground serve as an inexhaustible electron acceptor for microbial metabolism and therefore increase the biodegradation rate of the contaminants. Electricity can be produced within this process, making this novel bioremediation technology sustainable.
The main aim of the project is to prove the concept and identify the microbial, environmental and technical factors influencing the efficiency of the biodegradation process and electricity production.
