S. mutans prepared by conventional variable pressure SEM (VP-SEM) procedure. (a) VP-SEM 5000×. Bacterial towers are lined by a superficial granulation representing Eps secretion. Image was captured from the same sample observed in [50] Figure 2f. (b) VP-SEM 8000×. On S. mutans cells surface is clearly visible the fine graininess of freshly secreted Eps components. Image is the same of [50] Figure 2e.
