Simultaneous electricity generation and removal of Sars-Cov-2 from wastewater in microbial fuel cells

In this study, whether wastewater contaminated with SARS-CoV2 virus can be disinfected using microbial fuel cells was modeled using the S1 anchor protein of the virus.The disinfection potential and simultaneous electricity production of wastewater contaminated with SARS-CoV-2 mixed with wastewater using microbial fuel cells, an innovative technology, were investigated.Bioremediation of SARS-CoV-2 contaminated wastewater was modeled using SARS-CoV-2 surface antigen (S1) and studied in microbial fuel cells at different temperatures (30 °C vs. 25 °C).Our results show that microbial fuel cells gradually reduced the SARS-CoV-2 viral concentration from 213 ng/mL, especially at ambient temperature, and simultaneously achieved a power density of 184.19±21.31mW/m 2 at a current density of 0.073±0.029mA/ cm 2 .The log reduction rates of closed-circuit microbial fuel cells increased steadily from 0.005 to 0.163.In conclusion, microbial fuel cells can be used to simultaneously generate electricity to enable biological treatment of wastewater contaminated by SARS-CoV-2.
