Massive Survey on Bacterial-Bacteriophages Biodiversity and Quality of Natural Whey Starter Cultures in Trentingrana Cheese Production.

Front Microbiol 2021 14;12:678012. Epub 2021 Jun 14.

Food Quality and Nutrition Department, Research and Innovation Centre, Fondazione Edmund Mach (FEM), San Michele all'Adige, Italy.

This study focused on the microbial and bacteriophages identification and characterization in cheese-production facilities that use natural whey starter (NWS) cultures for Trentingrana production. Bacterial and phage screening was carried out on cooked not acidified whey and NWS samples isolated from six dairy factories, for 4 consecutive days in four different months. By means of a combined approach, using plate counts, bacterial isolation, and metataxonomic analysis was found occurring as the dominant species in NWS cultures and as codominant in the cheese factories where the temperature of NWS production was mainly lower than 40°C, suggesting that the variability in the parameters of the NWS culture preparation could differently modulate the bacterial species in NWS cultures.
