Luenced other surface-ripening cultures negatively. A. faecalis, which can be found in soil, water, and environments in association with humans and frequently considered non-pathogenic [19], has also previously been found on Livarot cheese [30]. The present study confirms the presence from the marine bacteria Marinilactibacillus psychrotolerans on cheese as this species was identified around the surface of cheese D. Each French and German cheeses have previously been reported to include M. psychrotolerans [14, 34]. It was recommended that M. psychrotolerans is transferred to the cheeses from the marine environments via sea salt. On the other hand, its potential role in cheese ripening remains unknown. Yeasts play an crucial part in deacidification on the cheese surface resulting from lactate assimilation and production of alkaline metabolites, e.g., ammonia [23, 46], which is prerequisite for improvement on the much less acid tolerant bacterial microbiota [4]. The present study confirms that Debaryomyces hansenii and Geotrichum spp. would be the dominating yeast species on surfaceripened cheeses. D. hansenii was located to become the dominating yeast species around the cheeses from dairies C and D, whereas Geotrichum spp. was discovered to dominate on the cheese from dairy B. Around the cheese from dairy A, Yarrowia lipolytica was the dominating yeast species. Y. lipolytica is really a naturally developing yeast species on cheese surfaces, and has in some situations been shown to swiftly outnumber other yeast species which includes D. hansenii and Geotrichum spp. [33]. This could explain why the latter yeast species will not be located on the cheese fromMicrobiota of Danish Cheeses Figure 4 DGGE profiles for cheeses from dairies A, B, C and D. a Bacteria from interior of your cheeses, b bacteria from the surface on the cheeses and c yeasts in the surface in the cheeses.

In conclusion, the interior bacterial microbiota on the Danish cheeses consisted of LAB starter cultures also as one particular or far more NSLAB. Noticeable for the bacterialcommunity of your cheese surfaces was that B. linens didn’t establish effectively on the cheeses, although it was used as ripening culture. Contrarily C. casei and/or C. variabile have been predominant, whereas the surface yeast microbiota resembled that otherwise stated in literature. Commonly, the Danish cheeses made at farmhou.
