Nally discovered in minor amounts. The cheese from dairy C was dominated by D. hansenii followed by a minor group of Geothrichum spp. Lastly, the cheese from dairy D was totally dominated by D. hansenii.Denaturing Gradient Gel Electrophoresis Culture dependent isolation followed by genotypic identifications was essentially confirmed by the culture-independent method, DGGE (Fig. 4). Also, inside the sample in the interior of your cheese from dairy A, DGGE band with strong intensity was identified as Streptococcus thermophilus. Moreover, DGGE bands with robust intensities in the cheese surface samples were located to represent Vagococcus carniphilus (the cheeses from dairies A, B and D), Psychrobacter spp. (the cheeses from dairies A and C) and Lb. curvatus (the cheese from dairy B) indicating that these bacterial species could play a function in cheese ripening, although they were not identified by the culture dependent approach. However, a number of main DGGE bands inside the samples from the cheese surface couldn’t be effectively identified.Discussion In addition to a culture dependent strategy, a culture independent strategy employing DGGE was integrated for identification in the microbial microbiota in Danish cheeses. Most significantly, the DGGE analysis discovered that Streptococcus thermophilus is present in raw milk cheese from dairy A, even though this thermophilic lactic acid bacterium was not610 Table 3 Identification of your interior bacterial community by culture dependent isolation followed by16S rRNA gene sequencingK.
