Apoptosis-induction effect of ε-poly-lysine against Staphylococcus aureus and its application on pasteurized milk

Antibacterial and anti‐biofilm of epsilon‐poly‐lysine hydrochloride on Listeria monocytogenes and its application on refrigerated beef

“…As a food preservative, ε‐PL is commonly added to food products to maintain good quality characteristics and protect against harmful microbes (Lin et al, 2018; Ning et al, 2021). Similarly, ε‐PLH treatment enhanced the beneficial effects significantly on overall acceptability of the beef streak samples during the storage, resulting in a longer sensory shelf life.…”

“…The decrease of the two intracellular enzymic activities exposed to ε-PLH could result in the inhibition of intracellular metabolism in the cells Tan et al (2019). demonstrated that ε-PL treatment inhibited the levels of metabolic intermediates of the Embden-Meyerhof-Parnas (EMP) pathway and induced the cell apoptosis in S. aureu(Ning et al, 2021). Typically, the pathway of EMP is considered as the biochemical index for glucose catabolism.…”

Purification, Fermentation Optimization, and Antibacterial Activity of Pyrrole-2-carboxylic Acid Produced by an Endophytic Bacterium, Bacillus cereus ZBE, Isolated from Zanthoxylum bungeanum

“…The effect of PCA on the S. aureus membrane integrity was investigated using the LIVE/ DEAD BacLight bacterial viability kit (Life Technologies, Eugene, OR) by flow cytometric analysis. 28 Logarithmic-phase S. aureus cells were resuspended in 0.85% saline (1 × 10 9 CFU/mL) and incubated with 1 × MIC and 2 × MIC of PCA at 37 °C for 6 h. Thereafter, cells were washed and resuspended in 0.85% saline (1 × 10 9 CFU/mL). Subsequently, the cell suspension (1 mL) was incubated with 60 μM propidium iodide (PI) and 10 μM SYTO 9 in the dark for 15 min at room temperature.…”

ε-Poly-l-Lysine Enhances Fruit Disease Resistance in Postharvest Longans (Dimocarpus longan Lour.) by Modulating Energy Status and ATPase Activity

“…ε-PL has been extensively utilized for preserving food products in America, China, and Japan [ 15 , 19 , 20 , 21 ]. In vitro research showed that ε-PL could efficiently prevent the growth of Alternaria alternata , Botrytis cinerea , Penicillium digitatum , Saccharomyces cerevisiae, and Staphylococcus aureus [ 15 , 22 , 23 , 24 , 25 ]. ε-PL was able to inhibit fruit disease development in the strawberry, cherry tomato, grape, apple, jujube, and citrus fruit [ 23 , 25 , 26 , 27 ].…”
