TTGE electrophoresis of V3 16S rDNA fragments from different samples of Domiati cheese. Samples 1 to 11 correspond to V3 16S rDNA regions PCR amplified from genomic DNA extracted from cheese samples (see Materials and Methods). After standardization of the gel by GelCompar software, bands are identified by comparison with the species database. Band a, PCR artifact; b, unidentified band; c, Lactococcus garvieae; d, Aerococcus viridans; e, unidentified band; f, Lactobacillus johnsonii, Lactobacillus gasseri; g, Lactobacillus plantarum, Lactobacillus pentosus; h, Acinetobacter lwoffii; i, Leuconostoc citreum; j, Enterococcus casseliflavus, Staphylococcus lentus; k, Leuconostoc mesenteroides; l, Staphylococcus epidermidis, Staphylococcus aureus, Staphylococcus simulans; m, Lactococcus raffinolactis, Staphylococcus equorum, Staphylococcus capitis; n, unidentified band; o, Enterococcus faecium group, Pseudomonas fluorescens, Leuconostoc pseudomesenteroides; p, Leuconostoc lactis, Staphylococcus xylosus, Lactobacillus brevis; q, Pseudomonas putida; r, Lactobacillus acidophilus group; s, Staphylococcus saprophyticus, Pseudomonas aeruginosa; t, Pediococcus pentosaceus, Macrococcus caseolyticus; u, Streptococcus uberis, Moraxella bovis; v, Enterococcus faecalis, Staphylococcus warneri; w, unidentified band; x, unidentified band; y, Staphylococcus chromogenes, Hafnia alvei, Pseudomonas alcaligenes; z, unidentified band; a′, Acinetobacter spp.; b′, Lactococcus lactis; c′, Streptococcus thermophilus. Markers: 1, Lactococcus garvieae CNRZ1323; 2, Lactococcus raffinolactis CNRZ1214; 3, Enterococcus faecalis CE17; 4, Lactococcus lactis subsp. lactis bv. diacetilactis CNRZ260. Lane M, TTGE standardization ladder; lane 1 to lane 11, cheese samples from 1 to 11.
