Procedure

In the culture system using p-cresol as an inducer, TCE was remarkably decomposed in the first 12 hours, and 5 ppm of TCE was completely decomposed after 18 hours. Quantitative analysis of p-cresol was done at this point using a spectrophotometer to confirm that p-cresol was completely decomposed. In the culture system using m-cresol as an inducer, remarkable decomposition of TCE started after about 12 hours of induction period and 5 ppm of TCE was completely decomposed after 30 hours. Quantitative analysis of m-cresol was done at this point using a spectrophotometer, and it was found that m-cresol was completely decomposed.
