Objective
A new bioconversion process involving the simultaneous oxidation of ammonia and the reduction of sulfates taken place under anaerobic conditions (redox potential of -425 mV) has been experimentally observed when treating industrial wastewater rich in organic carbon, nitrogen and sulfate. Experiments were performed in a Anaerobic Fluidized Bed Reactor (AFBR) filled with Granular Activated Carbon (GAC particles that were colonized by the biomass growing within the reactor. The mass balances of the different nitrogenous and sulfur compounds entering and leaving the reactor in the liquid and gas phases clearly indicated an uncommon evolution. An important percentage of the nitrogen entering the reactor as TKN (80% as ammonia) was removed from the liquid phase appearing as molecular nitrogen in the gas phase. Simultaneously, the sulfates entering the reactor disappeared being mostly transformed to elemental sulfur the rest appeared as sulfide in the liquid effluent or as hydrogen sulfide in the biogas. These experimental observations suggest a new anaerobic biological conversion involving simultaneous ammonium oxidation and sulfate reduction being ammonium the electron donor and sulfate the electron acceptor (Fdez.polanco et al. Water Research Vol.35(4) , pp.1111-1114 2001).Keeping in mind this fascinating scenario we seek outstanding post-doctoral researchers with competence in environmental microbiology. Candidates must hold a Ph.D. on Environmental Microbiology or close related field. They will be assigned for describing and characterizing the microbiology involved in the process (here named SURAMOX) including the tracking of chemical intermediates and products generated in the SURAMOX process. Candidates are expected to possess expertise isolating and characterizing groups, genera and species of anaerobic microorganisms. Additional expertise on biological processes for wastewater treatment will be valuable. Good knowledge of English or Spanish will be required.
