“…Increased biodegradation in higher pH regions, such as cathode, has been reported for one of the PCP-degrading enzymes produced by a species of Sphingobium UG30 [37]. In addition, a low pH has been reported as having a major negative impact on electrobioremedation by native soil microbial communities [38,39]. Accordingly, we observed a decrease in dehydrogenase activity at locations corresponding to the acid front.…”
