Research to date has attributed the special sensory properties of raw milk cheesesto the microbial shifts that occurduring cheese production and ripening. Therefore, in this researchthe microbiota of the traditional Idiazabal cheese from Basque Country was analyzed bymassive DNA sequencing. The results showed how the productionand ripening processesdetermined the microbiota of the cheese. In general, lactic acid bacteria (LAB)were predominant andtheirgrowth was favored throughboth processes.Most environmentaland pathogenicbacteria, however, were inhibited, except Staphylococcusaureus. It should be notedthat some bacteria whichuntil now had not been detected in Idiazabal cheese were identified, some of which are related to the synthesis of flavorcompounds.
Orain arte garatutako ikerketek, esne gordinaz egindakogazten ezaugarrisentsorial bereziak gazta egitekoeta heltzekoprozesuetan gertatzen diren aldaketa mikrobiarreiegotzi dizkiete. Horregatik, ikerketa honetan Euskal Herriko Idiazabal gazta tradizionalaren mikrobiota aztertu zenDNAren sekuentziazio masiboaren bidez. Gaztagileak eta heltze denborak gaztaren mikrobiotan duten eragina erakutsi zuten emaitzek. Oro har, bakterio azido laktikoak (BALak) nagusi zireneta hauen hazkuntza faboratu zenbi prozesuetan. Ingurumen-bakterio eta patogeno gehienak, aldiz, inhibitu egitenziren,Staphylococcusaureusizan ezik. Garrantzitsua da aipatzea orain arte Idiazabal gaztan detektatu ez diren bakterioak identifikatu zirela, aromarekin erlazionatutako konposatuensintesiarekinlotutakoak
