Abstract

The remarkable global diversity in long-ripened cheese production can be attributed to the adaptability of the cheese microbiota. Most cheese types involve intricate microbial ecosystems, primarily represented by lactic acid bacteria (LAB). The present study aims to review the microbial community’s diversity in dairy fermentation processes, focusing on two famous Italian cheeses, Grana Padano and Parmigiano Reggiano, produced using natural whey starter (NWS). NWS, created by retaining whey from the previous day’s cheese batches, forms a microbiological connection between daily cheese productions. Through this technique, a dynamic microbiota colonizes the curd and influences cheese ripening. The back-slopping method in NWS preparation ensures the survival of diverse biotypes, providing a complex microbial community in which interactions among microorganisms are critical to ensuring its technological functionality. As highlighted in this review, the presence of microbial cells alone does not guarantee technological relevance. Critical microorganisms can grow and colonize the curd and cheese. This complexity enables NWS to adapt to artisanal production technologies while considering variations in raw milk microbiota, inhibitory compounds, and manufacturing conditions. This critical review aims to discuss NWS as a key factor in cheese making, considering microbial communities’ ability to evolve under different selective pressures and biotic and abiotic stresses.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The third group is more diverse and abundant in artisanal cheeses and is functional in the curd fermentation process and capable of adapting to technological stress factors.

    “This group is more diverse and abundant in artisanal cheeses and, although not a biological element of stability and continuity in the ecosystem like natural whey starter, is functional in the curd fermentation process and capable of adapting to technological stress factors [8,123,124].”

    From Microbiota of Cheese Ecosystems: A Perspective on Cheesemaking (2025) · cites this paper as [8]

    Section 4 (page not provided) identifies the third group, part C, as necessary for curd fermentation and capable of adapting to technology-induced stress. It does not say that this group is more diverse or abundant in artisanal cheeses; it describes part C as a minority component of the natural whey microbiota. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
