Controlled Field Release of a Bioluminescent Genetically Engineered Microorganism for Bioremediation Process Monitoring and Control
Article Abstract:
Experiments that used pseudomonas fluorescens HK44, the first genetically engineered microorganism approved in the United States for field testing in bioremediation research. The results suggest that lux-based microorganisms promise to be useful in further studies of environmental contaminant biodegradation and bioavailability.

Quantitative relationship between naphthalene catabolic gene frequency and expression in predicting PAH degradation in soils at town gas manufacturing sites
Article Abstract:
A method of assessing catabolic gene expression in PAH-contaminated soils has been designed to overcome problems of measuring expression of biodegradative genes in difficult environments such as contaminated soils. The use of biodegradative gene technology may now become widespread in hazardous waste management, as the new method, based on an in situ soil mRNA quantitation technique, ensures that instant activity of soil microorganisms can be assessed and allows transcriptional monitoring of in situ soil bioremediation treatment methods.
