摘要：

Petroleum Chemical Extinguisher (R) (PCE) is polyethylene glycol(PEG) diester of fatty acid used in extinguishing fires and cleaning up oil spills. When PCE is added to garden soil, the amount of CO2 evolved indicates a near complete mineralization. Negligible increases in microbial biomass and acetylesterase activity resulted from PCE catabolism. PCE-exposed soil has enhanced activity to degrade PEG of average molecular weight 400, 1,000 or 1,450 but not 3,350. Potential uses of PCE in promoting biodegradation of PEG pollutants are discussed.
