Semi-specific biosensors for measuring BOD in dairy wastewater.
BACKGROUND: Semi-specific microbial biochemical oxygen demand (BOD) biosensors were constructed using living cells of Escherichia coliR17.1.3 (E. coli) and Raoultella terrigena P74.3 (R. terrigena)
Electrochemical Behaviour of HOPG and CVD‐Grown Graphene Electrodes Modified with Thick Anthraquinone Films by Diazonium Reduction
Highly oriented pyrolytic graphite (HOPG) and graphene grown on Ni (Ni-Gra) or Cu (Cu-Gra) by chemical vapour deposition were modified with thick anthraquinone (AQ) films (7−60 nm) by redox grafting
Semi-specific Microbacterium phyllosphaerae-based microbial sensor for biochemical oxygen demand measurements in dairy wastewater
This research aims to provide fast and more accurate BOD measurements in the dairy wastewater samples by constructing a semi-specific microbial biosensor based on Microbacterium phyllosphaerae, which is more suitable for BOD monitoring in dairy wastewater than P. fluorescens-based biosensor.
Electrochemical modification of gold electrodes with azobenzene derivatives by diazonium reduction.
Electrochemical quartz crystal microbalance, ellipsometry and atomic force microscopy investigations reveal the formation of multilayer films and it can be concluded that the FBK film is less compact or presents more pinholes than the electrografted GBC layer.
