Evaluation of microbial p-chloroaniline degradation in bioelectrochemical reactors in the presence of easily-biodegrading cosubstrates: Degradation efficiency and bacterial community structure
چکیده انگلیسی
This study aimed to illustrate p-Chloroaniline (p-CIA) biodegradation efficiencies in bioelectrochemical reactors under stimulation by a low-voltage electric field (0.2 V versus Ag/AgCl) in the presence of easily-degrading cosubstrates including glucose and acetate. The biodegradation efficiencies of closed-circuit bioreactors were compared with those of open-circuit reactors. Experimental results showed that the six different bioreactors provided different p-CIA biodegradation efficiencies. The highest biodegradation efficiency of 38.5 ± 10.3 mg/l was obtained in a closed-circuit bioreactor with acetate and the lowest biodegradation efficiency of 15.7 ± 9.4 mg/l was obtained in an open-circuit bioreactor. This difference may be attributed to the presence of electrical stimulation and acetate. The results for generated current and biodegradation efficiency indicated that acetate is a better cosubstrate than glucose. High-throughput sequencing technologies were used to characterise the bacterial community structure of the six bioreactors and revealed that different bacterial communities resulted in different treatment efficiencies.
