Comparison of the culture-dependent and culture-independent identifications of lactic acid bacterial and acetic acid bacterial genera in 17 sourdough samples from backslopped sourdoughs of different origins, indicated as presence (+) or absence (–) through colony identification, rRNA-PCR-DGGE, metagenetics, and metagenomics (only producer E), respectively.

The sample codes are as described in Table 1. When a genus was identified in a sample by at least one of the different methods, a green color was used.
