Research Topics

1.  Green energy from aromatic hydrocarbon-degrading bacteria using Bio Fuel Cells.

2. Bioremediation of toxic pollutants.

   In bioremediation: we design a bioreactor for bioremediation of toxic organic compounds. Petroleum hydrocarbons and their derivatives are the most widespread contaminants of soil and groundwater. Exposure to these molecules might lead to liver, kidney or nervous system damage. Long-term toluene inhalation is considered carcinogenic. The conventional remediation techniques are to dig-up contaminated soil and transfer it to a landfill or destroy the pollutants using physical and chemical methods.  Bioremediation methods constitute an attractive alternative to the conventional techniques. As biotechnology advances, bioremediation becomes one of the most rapidly developing fields of environmental restoration. Bioremediation methods use microorganisms to degrade environmental contaminants into less toxic forms. The methodology in this research consists of identification and monitoring of toxic organic compounds in treated wastewater. In addition, constructions of a laboratory scale bioreactor for bioremediation of toxic organic compounds. 

  In microbial fuel cell: we propose a novel MFC facility for domestic industry demands which will produce energy and simultaneously bioremediate wastewater. Our prime goal in this research is to study bacterial electroactivity for energy formation as well as toluene and phenol-bioremediation processes in a specifically designed microbial fuel cell. MFC are emerging as an excellent approach to treat oil components particularly aromatic hydrocarbons. The bacterial cells can use toxic organic compounds as a hydrocarbon source and transformed it directly to electricity through microbial metabolism. The overall process is economically favorable, not just as a mean of water treatment, but also as an alternative energy source. Nevertheless, state of the art in MFCs that utilized mixed bacterial strains which are not optimized for sewage bioremediation, the total power and bioremediation rates are expected to be low.  That is why in this research it is propose to use specific bacterial strains that are exoelectrogen (have a natural ability to transformed electrons to the anode in a MFC facility) and have the ability to bioremediate toxic organic-compounds as well. We expect that in future every chemical industry will have a MFC for energy generation and bioremediation.
