“…The use of chemical oxidants at certain concentrations to degrade pollutants can hamper further biodegradation processes [7]. However, recent studies indicate that, although chemical oxidation temporarily reduces microbial activity, bacterial populations have the ability to regenerate [11,15,16]. In addition chemical oxidation has also been suggested to improve further biodegradation by depleting toxic compounds for native microbial communities [17], improving the bioavailability of parent compounds [18,19] or providing oxygen to improve the aerobic conditions [20].…”
