Abstract
On-line estimation of lactic acid produced by Lactobacillus casei in a pilot scale reactor coupled with a microfiltration module is performe d by measuring the conductance on the permeate effluent. Non-interfere nce by other ions (inorganic and organic) present in the medium has be en verified. This method is found more reliable that the estimation of lactate concentration from the amount of alkaline solution supplied f or the pH control.
