Acidogenic profile of biofilms originated from different sugar-mediated aggregates. Results of glycolytic pH drop assays (glucose-fermenting). 19h biofilms were removed from the culture medium and transferred into a buffer solution containing glucose as the only carbon source. pH of the buffer was measured every 10 min. pH of the fresh culture medium was measured every 2h. Dotted box indicates the data used for proton production analysis (as shown in Table 1 ). G+F: glucose+fructose.
