PCR-DGGE was performed as described previously
(Vasilopoulos et al., 2008), using a denaturant gradient from 35% to
70%, and an appropriate bacterial reference ladder. DNA of visualised
bands of interest were excised from the gels with a sterile blade,
mixed with 40 ml of sterilewater, and placed at 4 C for 24 h to let the
DNA diffuse out of the bands. These bands were vigorously vortexed
for 15 min and centrifuged (21,036 g, 15 s, 4 C) to collect the
aqueous DNA solution.
