Molecular Mechanisms and Antioxidant Effects of Latilactobacillus sakei F1, Lacticaseibacillus paracasei D2, Lacticaseibacillus rhamnosus JL, and Weissella cibaria JLK Isolated from Spontaneously Fermented and Raw Food Products

An imbalance of pro-oxidants and antioxidants causes oxidative stress, contributing to various chronic diseases. Lactic acid bacteria (LAB) have recognised antioxidant activities that can help reduce oxidative stress. This study isolated fifty LAB strains from various fermented foods and raw vegetable products and evaluated their radical scavenging activity using DPPH and ABTS assays. Among them, four strains Lacticaseibacillus paracasei D2, Lacticaseibacillus rhamnosus JL, Latilactobacillus...
