| Figure 3:Shows the SEM of E-coli bacterial cells after ultrasonic treatment: (5a) Control (without treatment) (5b) 5 min; (5c) 10 min; (5d) 20 min; (5e) 30 min. The figures labeled with 130 kHz and 35 kHz frequency of ultrasonic treatment. Results observed the more distorted cells at 130 kHz and as well as decrease in cells population. Red boxes indicate the ruptured cells. |
