Abstract
A bioluminescent reporter strain, Acinetobacter sp. DF4-8, was constructed for the detection of phenol by inserting a mopR-like promoter upstream of the Vibrio fischeri bioluminescent luxCDABE gene cassette in a modified mini-Tn5 construct. When introduced into the chromosome of Acinetobacter sp. DF4, the bioreporter produced a sensitive bioluminescent response to phenol at concentrations ranging from 2.5 to 100 ppm. This response was linear (R(2)=0.986) in the range from 20 to 90 ppm. A significant bioluminescent response was also recorded when strain DF4-8 was incubated with slurries from aged, phenol-contaminated soil.
