Table 5 Effect of magnetic separation time on recovery (n = 5, mean±SD).

Magnetic separation time (min)	Colony forming unit (CFU/mL)	Recovery¹ (%)
1	40.80±6.91	42.50±7.19
2^b	88.20±6.30	91.88±6.56
3	90.00±5.70	93.75±5.94
4	91.00±6.89	94.79±7.18
5	90.40±5.59	94.17±5.83

^bP<0.01 vs 1 min of magnetic separation time.

¹There were 96 CFU/mL in the dilution (mean of five samples).
