A novel electrochemical method for the identification of microorganisms
A novel electrochemical method for the recognition of different species of microorganisms has been developed. It consists of sampled DC voltammetry applied directly to microbial cultures or to the supernatants of these cultures obtained following centrifugation. Pt, Au, and glassy carbon working ele...

A novel electrochemical method for the recognition of different species of microorganisms has been developed.
