  1. 1 128 isolates, i.e. ca. 25 isolates per media, were analyzed by TTGE and grouped into identical TTGE profiles. A representative isolate of each profile was identified by 16S rDNA sequencing. After the assignment of all isolates to a species, the percentage of each species on each of the five media was assessed. The cell count of a species was calculated by multiplying percentage and cell count determined for the corresponding media.
  2. 2 Closest 16S rDNA sequence in the GenBank public database http://www.ncbi.nlm.nih.gov.
  3. 3 Total cell count was determined on TGYA. In addition, staphylococci were enumerated on BP agar and MSA, lactic acid bacteria on MRS agar and enterococci on KFS agar.
  4. 4 Given the polymorphy in the intraspecies diversity of B. linens (Oberreuter et al. [52]), strain assignation to B. linens or the related species B. aurantiacum based on 16S rDNA analysis only was considered not reliable.
