A method for determination of the growth rate of biofilm using an electrical impedance analyses is disclosed. The method comprises the steps of: bringing a culture medium fluid in contact to an electrode structure, having biofilm grown within the fluid culture medium with the biofilm arranged in distance to the electrodes structure, so that the fluid culture medium is placed between the growing biofilm and the electrode structure; measuring the impedance of the electrodes structure over a monitoring time, and determining the growth rate of the biofilm as a function of the reduction rate of the impedance values measured on the electrode structure.
