DGGE profiles of V3-16S rDNA amplicons of total DNA extracts from 11 Karakačanski skakutanac cheeses. The samples were collected from a dairy farm at 14-day intervals from April (1) to September (11). M – marker composed of A-Lb. delbrueckii subsp. lactis, B-Ec. faecalis, and C-Lc. lactis subsp. lactis. Sequences of selected bands (indicated by arrows) were 100% homologous to Lc. lactis subsp. cremoris (Accession No. AM944595). n.r. – not reamplifed. The gel shown is not normalized.
