Quantitative ERIC-PCR results with regard to the detection limit of ERIC-PCR primers that used whole bacterial cells from culture concentrates and subsequent 10-fold dilutions containing 106 to 10 CFU/ml (a). ERIC-PCR patterns obtained from different food samples with declared content of bifidobacteria (b). (a) Lanes 1 to 6, direct detection of B. lactis; lane 7 to lane 12, direct detection of B. bifidum ATCC 35914; lanes 13 to 18, direct detection of B. breve ATCC 15701; and lanes 19 to 24, direct detection of B. longum ATCC 15708. (b) Lane 1, sample 15 containing only B. bifidum; lane 2, sample 16 containing only B. breve; lane 3, sample 13 containing only B. longum; lane 4, sample 1 containing only B. lactis; lane 5, sample 6 containing B. longum and B. bifidum; lane 6, sample 7 containing B. longum and B. bifidum; lane 7, sample 8 containing B. longum and B. bifidum; and lane M, 1-kb DNA ladder (Gibco BRL).
