Combined laboratory/field study on the use of nitrate for in situ bioremediation of a fuel-contaminated aquifer
Article Abstract:
A pilot demonstration study compared the extent of bioremediation of a fuel-contaminated aquifer at Eglin Air Force Base, FL, using sprinkler application with and without nitrate addition. The study focused on contaminants BTEXTMB (benzene, toluene, ethlybenzene, xylenes and trimethybenzenes) and the JP-4 jet fuel. Based on periodic core analyses, BTEXTMB was reduced in both treatment modes, equivalent to a mass loss of 106 and 21 kg in the nitrate cell and control cell, respectively. Combined laboratory and field data suggested that contaminant reduction occurred due to to anaerobic remediation and soil washing.

Development of tyrosinase-based biosensor and its application for monitoring of bioremediation of phenol and phenolic compounds
Article Abstract:
A solid tyrosinase-based composite biosensor was found to be effective in monitoring phenol remediation in water and soil. Laboratory experiments also reveal that sensitivity decreased 20% after one month and that sensitivity was restored 100% after surface renewal. Working potential, buffer concentration, pH and response with other compounds was also determined. The use of biosensor analysis in phenol monitoring is faster, simpler, offers the possibility to perform measurements outside the laboratory as well as low cost instrumentation.

In situ bioremediation: defining the limits
Article Abstract:
Intrinsic or in situ bioremediation is increasingly becoming a popular alternative to other cleanup methods because it is cheaper and brings faster results. Experts, however, warn that in situ bioremediation is not the panacea to environmental pollution. Recent studies testing the applicability of this approach showed that it may have adverse effects on the environment when it is not monitored properly. Furthermore, it needs to be biocompatible with other methods to be successful.
