Bioluminescence induction was tested in minimal medium. At 15 °C the highest bioluminescence induced with toluene (1.325 mg/L) was reached after 6 h. At 25 °C the bioluminescence maximum was approximately 20% lower but this was reached after 3.5 h, and at temperatures of 7 °C, 28 °C, 30 °C and 34 °C, bioluminescence peaked at ≤60% of the maximum. Time courses of bioluminescence were dependent on cell concentrations. The heights of bioluminescence maxima were proportional to toluene concentration in the range 0–26 mg/L. Twenty-three organic pollutants were tested as bioluminescent inducers. Bioluminescence was also induced with ethanol and methanol and the presence of these alcohols in concentrations of ≤1% increased bioluminescence of toluene. The induction of bioluminescence from samples of wastewater and groundwater contaminated with BTEX from 0.5 to 120 mg/L was demonstrated.
