S-Doped NiFe₂O₄ Nanosheets Regulated Microbial Community of Suspension for Constructing High Electroactive Consortia.

ABSTRACT: Iron-based nanomaterials (NMs) are increasingly used to promote extracellular electron transfer (EET) for energy production in bioelectrochemical systems (BESs). However, the composition and roles of planktonic bacteria in the solution regulated by iron-based NMs have rarely been taken into account. Herein, the changes of the microbial community in the solution by S-doped NiFe₂O₄ anodes have been demonstrated and used for constructing electroactive consortia on normal carbon cloth anodes, which could achieve the same level of electricity generation as NMs-mediated biofilm, as indicated by the significantly high voltage response (0.64 V) and power density (3.5 W m^-2), whereas with different microbial diversity and connections. Network analysis showed that th
