Tractable microbial communities are needed to bridge the gap between observations of patterns of microbial diversity and mechanisms that can explain these patterns. We developed cheese rinds as model microbial communities by characterizing in situ patterns of diversity and by developing an in vitro system for community reconstruction. Sequencing of 137(More)
AIMS The aim of this work was to obtain a deeper insight into the knowledge of microbial composition of Parmigiano Reggiano natural whey starters through different culture-independent methods. METHODS AND RESULTS Eighteen different Parmigiano Reggiano natural whey starters sampled from three different provinces of this cheese production area and the(More)
This work aimed to investigate the effects of thermal treatments and yeast extract addition on the composition of the microbial community of natural whey starters for Grana Padano cheese. Different natural whey starter samples were held at 4 degrees C for 24 h (cooling treatment), or at -20 degrees C for 24 h (freezing treatment) to evaluate the possibility(More)
Microbial succession during Parmigiano-Reggiano cheesemaking was monitored by length heterogeneity PCR (LH-PCR), considering the intact and lysed cells at different stages of cheese production and ripening. When starter species underwent autolysis, species coming from milk were able to grow. For the first time, the LH-PCR technique was applied to study a(More)
Grana Padano (GP) is a Protected Designation of Origin cheese made with raw milk and natural whey culture (NWC) that is characterised by a long ripening period. In this study, six GP productions were considered in order to evaluate the trend of microbial dynamics and compare lactic acid bacteria (LAB) population levels in cheeses during the entire(More)
The aim of this study was to explore diversity and dynamic of indigenous LAB strains associated with a long ripened hard cheese produced from raw milk and undefined natural starter such as PDO Grana Padano cheese. Samples of milk, curd, natural whey culture and cheeses (2nd, 6th, 9th and 13th months of ripening) were collected from 6 cheese factories in(More)

Twenty-one natural whey starters, collected from dairy factories located in six provinces of the Grana Padano production area, were characterized. Basic techniques, such as acidity evaluation and microbial plate count, together with more complex methods such as the Live/Dead® BacLight™ bacterial viability kit, have been used. Seven parameters, including pH,(More)
