Fig. 1From: Investigations of biofilms formed on silica in contact with aqueous formulations containing laccase and maltodextrinResults of frequency changes during QCM-D measurements as a function of experimental time. Silica coated QCM-D crystals in contact with 0.2 M aqueous sodium acetate buffer (stage I), with 0.1 mg/ml laccase mixture suspension (stage II), and finally rinsing with 0.2 M aqueous sodium acetate buffer (stages IV and V)Back to article page
