DGGE analysis of the bacterial diversity in the milk samples. Lanes: I and II, DGGE identification markers. DGGE marker I comprises the species listed from (a) to (i) in the Figure 1 legend while DGGE marker II contains the species listed from (j) to (p). M1 to M20, DGGE profiles of samples M1 to M20. Bands identified by gel excision and PCR sequencing are indicated by letters from (q) to (z) and from (α) to (γ), and correspond to the following bacteria: q, Gemella haemolysans [EMBL: AM774574]; r, Acinetobacter sp. [EMBL: AM774586]; s, Staphylococcus capitis [EMBL: AM774573]; t, Arthrobacter sp. [EMBL: AM774575]; u, Streptococcus suis [EMBL: AM774576]; v, Streptococcus cristatus [EMBL: AM774577]; w, Streptococcus pneumoniae [EMBL: AM774579]; x, Streptococcus anginosus [EMBL: AM774580]; y,Lactobacillus animalis [EMBL: AM774581]; z, Lactococcus lactis [EMBL: AM774582]; α, Lactococcus garvieae [EMBL: AM774583]; β, Propionibacterium acnes [EMBL: AM774584]; γ, Neisseria weaveri [EMBL: AM774585]. The arrows indicate the bands that matched with sequences identified as" uncultured bacterium DGGE band 16S ribosomal RNA gene" in the database.
