Abstract
This research has demonstrated that GEMs can be introduced and maintained in environmental soils for at least 18 months and that the population dynamics can be affected by nutrient augmentation. For example, the presence of naphthalene can be used to enrich for P. fluorescens HK44 in soils and the lack of naphthalene causes the GEM population to decline. Furthermore, this study has provided evidence that bioluminescence from GEMs can be used as a tool for monitoring and controlling the bioremediation process. A GEM can bioluminesce and report conditions that are favorable for bioremediation. In the case where a GEM is present and not bioluminescing, unfavorable environmental or physiological conditions are revealed. If unfavorable conditions are detected, analytical and microbiological assays as well as localized treatments can be used to diagnose and correct the existing problem. This strategy can lead to rapid responses and eliminate the need for expensive microcosm studies that may or may not be amenable to scale-up.
