The reversible electron transfer of self-organized microbial biofilm was employed to perform biomolecular logic gate operations. In such a system, catalytic currents could be produced from the oxidation of acetate and reduction of oxygen catalyzed by the self-assemble microbial biofilm. The biocomputing operations were conducted by designing acetate and oxygen as the inputs and electric current as the output. By applying different potentials, different logic operations were achieved from the system, including XOR, AND-OR and OR-AND. The formation of a bacterial biofilm allowed the stability and scalability of this system, which may find applications in monitoring and controlling of wastewater treatment, bioelectricity generation, and bioremediation process.
