Yeast-catalyzed alcoholic fermentation (sugar consumption) is a crucial step in industrial processes (food and biofuel) that results in the transformation of sugars (glucose and fructose) into alcohol and carbon dioxide [ 1 ]. The yeast Saccharomyces cerevisiae has been known for thousands of years and is routinely used in many traditional biotechnological processes, including bread making and the production of several alcoholic beverages [ 2 ].
A variety of techniques have been proposed for monitoring the sugar consumption by yeast, such as

, samples only containing released substances, samples containing only cells and samples of secreted substance after filtration. In this work, the changes in the CPE magnitude were due to, not only yeast attachment but also to changes in conductivity. When the results of samples after filtration and total sample without filtration were compared, between 50% and 70% of changes in CPE were due to the suspending medium [ 21 ].
The adherence of eukaryotic cells to planar gold film electrodes has also been studied by other groups [ 22 , 23 , 24 , 25 , 26 , 27 ]. Nor do
