Figure S1: Cavities in spoiled cooked ham.
Figure S2: DGGE profiles of the nucleic acids extracted directly from the samples. Lines a, f, and i: Reference pattern used for the gel normalization (Bands 8 and 5: L. casei (DSMZ 20111); band 7: L. curvatus (DSMZ 20019); band 6: L. rhamnosus (DSMZ 20022). Bands that were observed in lines b, c, d, e, g, and h were were excised, and, after reamplification and cloning, they were subjected to sequencing. All bands migrating the same distance of Band 1 corresponded to Lc. carnosus. Bands showing the same migration profile of band 2 corresponded to L. sakei. Bands migrating the same way of band 3 corresponded to Lc. mesenteroides. Finally, bands migrating as band 4 corresponded to Weissella viridescens.
