Abstract

Maintenance of a high degree of biodiversity in homogeneous environments is poorly understood. A complex cheese starter culture with a long history of use was characterized as a model system to study simple microbial communities. Eight distinct genetic lineages were identified, encompassing two species: Lactococcus lactis and Leuconostoc mesenteroides. The genetic lineages were found to be collections of strains with variable plasmid content and phage sensitivities. Kill-the-winner hypothesis explaining the suppression of the fittest strains by density-dependent phage predation was operational at the strain level. This prevents the eradication of entire genetic lineages from the community during propagation regimes (back-slopping), stabilizing the genetic heterogeneity in the starter culture against environmental uncertainty.

  • This resistance can be attributed to the presence of bacteriophages within complex starter cultures, where they drive the generation of genetic and phenotypic diversity.

    “This phenomenon can be attributed to the presence of bacteriophages within complex starter cultures, where they play an essential role as part of the microbial community, driving the generation of genetic and phenotypic diversity in the microbial population [27,28].”

    From Microbiota of Cheese Ecosystems: A Perspective on Cheesemaking (2025) · cites this paper as [27]

    The Introduction reports bacteriophages in the complex cheese starter culture and identifies phage predation as part of the basis for its resilience. The Discussion says phage predation preserves strain diversity by suppressing abundant strains, while the study also documents variation in phage sensitivity. It does not establish that phages generate new genetic and phenotypic diversity, rather than help maintain existing diversity. (LLM, conf=0.85)

  • Fluctuations in plasmid content among natural communities give rise to subpopulations that offer selective advantages in the face of environmental uncertainty.

    “Thus, fluctuations in plasmid content among natural communities give rise to subpopulations that offer selective advantages in the face of environmental uncertainty [27].”
  • The "kill the winner" model explains how strong duplication of a specific strain within a microbial community triggers a corresponding increase in viral populations that target that strain, resulting in a reduction in the population size of the rapidly growing strain, ultimately promoting diversity within the overall community.

    “In this context, the “kill the winner” model is intriguing. It explains how the strong duplication of a specific strain within a microbial community triggers a corresponding increase in viral populations that target that strain. This results in a reduction in the population size of the rapidly growing strain, ultimately promoting diversity within the overall community [27].”

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.
