FIG. 1.

Dechlorination of fthalide by the KFL culture supplemented with 20 mM lactate. (A) Changes in the concentrations of fthalide and its dechlorinated metabolites. (B) Lactate and the transformed organic acids. (C) Gaseous metabolites. (D) Total cell counts. The data are averages and standard deviations of determinations from three different culture bottles, independently prepared in parallel. See Materials and Methods for the abbreviations of the chemicals. *, 4,5-DCPH was tentatively quantified using the calibration curve for 4,7-DCPH, because no chemical standard is available.
