Biofilm growth from wastewater on MWNTs and carbon aerogels

The improving carbon nanostructure bioactivity related to a specific microorganism community is an important research goal of bionanotechnology. The functionalized CNTs are used to improve the bioaffinity of working electrode in microbial fuel cells and wastewater treatment. Beside CNTs, carbon aerogel is another carbon material with high surface area, high open porosity and controllable morpho-structural characteristics. In the present work we investigate the biofilm growth from wastewater on functionalized CNTs and carbon aerogels. The biofilm growth on CNTs and carbon aerogel was monitored by optical and scanning electron microscopy. The influence of the bacterial growth phase on carbon electrode was assessed by cyclic voltammetry measurements in wastewater and 0.3 M potassium phosphate buffer solution.
