Abstract

A total of 26 lactic acid bacteria isolates from both Italian and Brazilian cheeses were tested for their use in cheesemaking. Isolates were screened for salt tolerance, exopolysaccharide and diacetyl production, lipolytic, acidifying, and proteolytic activities. In addition, the aminopeptidase (Pep N and Pep X) activities, were evaluated. Most of the strains demonstrated salt tolerance to 6% of NaCl, while only two L. delbruekii (P14, P38), one L. rhamnosus (P50) and one L. plantarum (Q3C4) were able to grow in the presence of 10% (w/v) of NaCl. Except for 2 L. plantarum (Q1C6 and Q3C4), all strains showed low or medium acidifying activity and good proteolytic features. Furthermore, lipolytic activity was revealed in none of the strains, while the production of EPS and diacetyl was widespread and variable among the tested strains. Finally, regarding aminopeptidase activities, 1 L. delbrueckii (P10), 1 L. rhamnosus (P50), and 1 L. lactis (Q5C6) were considered as the better performing, showing high values of both Pep N and Pep X. Based on data presented here, the aforementioned strains could be suggested as promising adjunct cultures in cheesemaking.

  • During ripening, an extremely complex set of biochemical changes occurs through the catalytic action of coagulants, indigenous milk enzymes, starter bacteria and their enzymes, and secondary microbiota and their enzymes.

    “During ripening, an extremely complex set of biochemical changes occur through the catalytic action of the following agents: coagulants; indigenous milk enzymes, especially plasmin and lipoprotein lipase, which are particularly important in cheese made from raw milk; starter bacteria (SLAB) and their enzymes; and secondary microbiota (NSLAB) and their enzymes [115,116,117].”

    From Microbiota of Cheese Ecosystems: A Perspective on Cheesemaking (2025) · cites this paper as [116]

    The Introduction describes roles for starter and non-starter LAB during cheesemaking and ripening, and says coagulating enzymes and microbial proteinases release peptides from milk caseins. It does not identify indigenous milk enzymes, including plasmin and lipoprotein lipase, as contributors to the ripening changes attributed to this source. No page numbers are available in our copy.

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.
