Flame-Oxidized Stainless-Steel Anode as a Probe in Bioelectrochemical System-Based Biosensors to Monitor the Biochemical Oxygen Demand of Wastewater

Abstract

Biochemical oxygen demand (BOD) is a widely used index of water quality in wastewater treatment; however, conventional measurement methods are time-consuming. In this study, we analyzed a novel flame-oxidized stainless steel anode (FO-SSA) for use as the probe of bioelectrochemical system (BES)-based biosensors to monitor the BOD of treated swine wastewater. A thinner biofilm formed on the FO-SSA compared with that on a common carbon-cloth anode (CCA). The FO-SSA was superior to the CCA in terms of rapid sensing; the response time of the FO-SSA to obtain the value of R2 > 0.8 was 1 h, whereas the CCA required 4 h. These results indicate that the FO-SSA offers better performance than traditional CCAs in BES biosensors and can be used to improve biomonitoring of wastewater.

Microbial Biosensors for Rapid Determination of Biochemical Oxygen Demand: Approaches, Tendencies and Development Prospects

“…The formation of biofilms on various surfaces leads to interesting results. For example, in [ 102 ] it has been shown that a thinner biofilm of microorganisms is formed on a flame-oxidized stainless-steel anode than on a common carbon cloth anode, which improved the performance of MFCs and leads to faster measurements.…”

Recent advances in the potential applications of luminescence-based, SPR-based, and carbon-based biosensors

“…As a result, the developed biosensor offered better performance than traditional carbon-cloth anodes in bioelectrochemical biosensors. The authors further proposed various practical utilizations of the biosensor to improve the biomonitoring of wastewater (Liang et al 2018 ). The great challenge nowadays is the monitoring of the marine environment.…”

“…Liang, Yamashita, Yamamoto‐Ikemoto, and Yokoyama (2018) analyzed a flame‐oxidized stainless steel anode (FO‐SSA) and used as the probe of bioelectrochemical system (BES)‐based biosensors to monitor the biochemical oxygen demand (BOD) of treated swine wastewater. The FO‐SSA was superior to the CCA in terms of rapid sensing and offered better performance than traditional CCAs in BES biosensors.…”
