Fig. 4

One of the DGGE profiles, chosen as it shows the greatest diversity of bacteria and fungi as compared to others. Bacteria (a) and fungi (b) are in separate gels. Lanes: 1, artefact 1; 2, artefact 2; 3, artefact 3; 4, artefact 4. The numbered bands were excised and the results of species identification by sequencing the bands are shown in Table 2. B1–B4 shows bacterial DGGE bands and F1–F7 show fungal DGGE bands
