The proposed project period is three years and the total GCHSRC funding requested is as follows: $49,811 (Year 1), $49,555 (Year 2) and $49,917 (Year 3). The final product of this research effort will be a cDNA subtraction tool which has been developed specifically for delineating biodegradation pathways utilized in environmental treatment applications. Rather than having to sequence the whole genome of a particular microbial species (a multiyear effort), the cDNA subtraction method allows one to delineate those genes expressed only during the biodegradation of a particular pollutant. Since this effort is much more focused, it allows one to identify the environmentally relevant genes in a matter of days or weeks. This information lays the foundation for efficient development of molecular probes to monitor gene expression in ex situ or in situ biological treatment systems. The ultimate cost savings provided by the cDNA subtraction method coupled with focused gene expression will likely be site and treatment system specific. However, if one considers the hundreds of thousands (to multimillions) of dollars that are often spent to investigate and remediate a single hazardous waste site, successful deployment of this molecular tool has the potential to provide significant cost savings.
