Abstract
The heterocontinuous flow cultivation technique was used for the study of 2-chlorobenzoic and 2,5-dichlorobenzoic acid degradation in soil c olumns inoculated with Pseudomonas stutzeri. 2-Chlorobenzoic and 2,5-d ichlorobenzoic acids disappeared from the soil columns within 8 and 12 d, respectively. The presence of the haloaromatics increased the surv ival of strain KS25 in soil. Viable cell numbers in the soil columns f lushed with 2-chlorobenzoic and 2,5-dichlorobenzoic acids were 1.3 and 2 times higher, respectively, than those without the chlorobenzoic ac ids after 30 d of incubation.
