Graphene oxide composite membrane accelerates organic pollutant degradation by <i>Shewanella</i> bacteria

Abstract Degradation of various organic pollutants by bacteria has been proved to be an economical and environmentally friendly method. The key challenge in making these technologies widely available is their low degradation efficiency. Here, we report a composite membrane composed graphene oxide polyvinyl alcohol (GO-PVA) which can markedly enhance the efficiency rate Shewanella degrade Congo red (CR). alone on CR solution was about 42% at 72 h. After addition GO-PVA membrane, reached 91% time 36 increased two times four presence compared alone. This indicates that could rapidly completely degraded increasing input amounts process algae CR. Moreover, showed good recyclability reusability. biocatalysts performance did not decrease after 10 cycles. Furthermore, role products were discussed.
