Abstract

Several artisanal cheeses are elaborated in European countries, being commonly curdled with rennets of animal origin. However, in some Spanish regions some cheeses of type “Torta” are elaborated using Cynara cardunculus L. rennets. Two of these cheeses, “Torta del Casar” and “Torta de Trujillo”, are elaborated in Cáceres province with ewe’s raw milk and matured over at least 60 days without starters. In this work, we identified the lactic acid bacteria present in these cheeses using MALDI-TOF MS and pheS gene analyses, which showed they belong to the species Lactobacillus curvatus, Lactobacillus diolivorans, Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactococcus lactis and Leuconostoc mesenteroides. The pheS gene analysis also allowed the identification of the subspecies La. plantarum subsp. plantarum, La. paracasei subsp. paracasei and Le. mesenteroides subsp. jonggajibkimchii. Low similarity values were found in this gene for some currently accepted subspecies of Lc. lactis and for the two subspecies of La. plantarum, and values near to 100% for the subspecies of Le. mesenteroides and La. paracasei. These results, which were confirmed by the calculated ANIb and dDDH values of their whole genomes, showed the need to revise the taxonomic status of these species and their subspecies.

  • Within the genus Leuconostoc, the species Ln. mesenteroides, Ln. peseudomesenteroides, and Ln. citreum have been detected in artisanal cheeses produced from raw milk.

    “Within the genus Leuconostoc, the species Ln. mesenteroides, Ln. peseudomesenteroides, and Ln. citreum have been detected in artisanal cheeses produced from raw milk [122,123,124,125].”

    From Lactic Acid Bacteria in Raw-Milk Cheeses: From Starter Cultures to Probiotic Functions (2022) · cites this paper as [124]

    The Introduction states that Torta del Casar is made from ewe’s raw milk, and the Conclusions identify Leuconostoc mesenteroides in the two Torta cheeses studied (page numbers unavailable). The paper does not report detecting Ln. pseudomesenteroides or Ln. citreum, so it supports only one of the three species named. (LLM, conf=0.90)

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.
