Simultaneous degradation of bad wine and electricity generation with the aid of the coexisting biocatalysts Acetobacter aceti and Gluconobacter roseus

► Direct bioelectrocatalysis of Acetobacter aceti., and Gluconobacter roseus. ► High power with a mixed culture of Acetobacter aceti., and Gluconobacter roseus. ► Bad wine as a fuel for current generation. ► Microbes perform the dual duty of bad wine degradation and current generation. ► Scope of using microbial fuel cells in wineries.
