Degradation of 2-chlorobenzoic and 2,5-dichlorobenzoic acids in pure culture by Pseudomonas stutzeri
The bromoxynil-degrading soil microorganism Agrobacterium radiobacter was used for degradation of the herbicide under nonsterile batch and continuous conditions. From four types of carrier particles, beech shavings showed the best stability of the bacterial biofilm, bromoxynil concentration in a column reactor decreasing to 65% after 5 d. The efficacy of degradation was enhanced by addition of ferrous, cobaltous or cupric ions.

3-Chloropyrocatechol is formed as a result of oxidation of 2-chlorobenzoate by Pseudomonas stutzeri. 2-Chloro-cis,cis-muconic acid is the product of oxidation of 3-chloropyrocatechol. A catabolic pathway for the degradation of 2-chlorobenzoate by a newly isolated strain of P. stutzeri is proposed.

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