The authors wish to thank Professor Elvira Rios Leal and Cirino Rojas (B.S. Chem.), head and research technician respectively of the Chromatographic Services of the Biotechnology Department, CINVESTAV, for their expert assistance in the chromatographic analyses of transformer oil. This research was supported by a grant from the Instituto Mexicano del Petróleo (FIES 96 105 VI), Mexico D.F., Mexico.

N2 - In this study polychlorinated biphenyls (PCBs, mostly penta to heptachlorinated isomers) from transformer oil were degraded under aerobic conditions in liquid culture using a mixed culture isolated from a soil contaminated with polychlorinated biphenyls and other hydrocarbons. Microorganisms in the mixed culture were identified as Comamonas acidovorans, Acinetobacter calcoaceticus, Achromobacter sp., Pseudomonas sp., Flavobacterium devorans, Bacillus lentus, Bacillus mascerans and Bacillus thuringiensis. A fungus of the genus of Paecilomyces and one strain belonging to Actinomyces were partially identified. The mixed culture could remove 75% of PCBs (88% w/v in the transformer oil). Our results provide evidence that naturally occurring aerobic microorganisms in the soil have the potential to attack PCBs. Copyright (C) 1999 Elsevier Science B.V.
