Salt Stress Accelerates Tyrosine Depletion by Enterococcus lactis KUST2812: Multi-Omics Insights into Metabolic Remodeling

Abstract

Enterococcus lactis KUST2812 is a halotolerant strain isolated from broad bean paste (BBP). It shows strong potential as a safe fermentation starter due to its high survival rate (98.32% in 18% NaCl), absence of hemolytic activity, and susceptibility to clinically relevant antibiotics, with resistance limited to intrinsic traits. Growth and metabolic dynamics suggest that salt stress decouples growth from tyrosine catabolism: while 6% NaCl significantly inhibited bacterial cell growth, tyrosine depletion occurred within 12 h under 6% NaCl, compared with the 96 h required under non-saline conditions. Multi-omics analyses suggest a molecular network associated with this tyrosine conversion under salt stress. Two tyrosine decarboxylase genes (tdc) were upregulated by 1.85- and 6.50-fold, respectively. The tyrosine-specific transporter gene tyrP was upregulated 4.99-fold, and the protein synthesis-associated gene tyrS was upregulated 4.93-fold. These changes collectively support a diversified tyrosine utilization strategy of E. lactis KUST2812. Moreover, coordinated responses involving the Na+/H+ antiporter system, compatible solute transporters, and oxidative stress markers contributed to the metabolic basis for salt adaptation of this strain. Evaluation in BBP fermentation suggested that E. lactis KUST2812 may reduce tyrosine accumulation without causing a significant increase in tyramine. These findings offer a potential microbial resource and a theoretical basis for managing tyrosine-related quality issues in fermented foods.

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.
