Table 1.

Viable cell numbers of the tested samples before and after DEP treatment determined by plate counting on MOX plates, along with the calculated percentage differences.

Sample	Cell number before DEP treatment (in 50 μl)	Cell number after DEP treatment (in 50 μl)	Percentage change
1	(2.60 ± 0.99) × 108	(6.30 ± 0.71) × 107	-75.8%
2	(4.60 ± 0.61) × 108	(4.70 ± 1.41) × 107	-89.7%
3	(4.75 ± 1.27) × 108	(2.05 ± 0.87) × 108	-56.8%
4	(1.60 ± 0.41) × 108	(3.30 ± 0.64) × 107	-68.9 %

Cell numbers were averaged from colony counts on 3–5 plates.

DEP treatment: 5 MHz and 20 Vpp for 4 h.
