Abstract:

Meta- and para-nitrobenzoic acid are pollutants found in waste streams from metal-stripping processes using cyanide-free solvents. The Kelly AFB industrial Waste Treatment Plant IWTP is currently incapable of removing these compounds from its wastewaters because of the presence of significant quantities of ethylenediamine, a preferred substrate and and upper limit of 4-5 hours on the hydraulic residence time in the IWTP. This report describes the enrichment and preliminary characterization of a microbial consortium capable of utilizing both Meta- and Para-Nitrobenzoate as sole carbon sources.
