Fig. 4. Inhibition of biofilm development using 96-well microtiter plate. Seventeen μg of purified JydB and Aeromonas sp. T3-4 were cultivated together in a 96-well microtiter plate for 12 h. Turbidity was measured at OD600 prior the treatment with 0.1% crystal violet (black bars). Formation of biofilm was measured at OD550 (gray bars). Heat inactivated JydB was used as control. All experiments were carried out in triplicates and data were exhibited as the mean ± the standard deviation. **p < 0.01.
