MICROBIAL DEGRADATION OF 4-CHLOROBENZOIC ACID BY Pseudomonas putida STRAIN PS–I
Journal Title: Indian Journal of Scientific Research - Year 2018, Vol 8, Issue 2
Abstract
Pseudomonas putida strain PS- I, a 4-chlorobenzoic acid degrading bacteria was isolated from soil. This bacterium could degrade 13 mM of 4-chlorobenzoic acid rapidly with stiochiometric formation of chloride ion. Metabolites such as 4-chlorocatechol and cis, cis- muconic acid could detect in the grown medium. Further, ring cleavage enzyme catechol 1, 2- dioxygenase detected in crude cell extract. Thus, the biodegradation pathway of 4-chlorobenzoic acid by this bacterium was proposed involve the 4- chlorocatechol as intermediate compound and further this converted into cis, cis- muconic acid by the process ortho ring cleavage pathway.
