Effect of weak acids, combined with pH and temperature, on the growth or inactivation of Alicyclobacillus acidoterrestris

Ultrasound promoted the inactivation efficacy of lactic acid against calcium‐mediated biofilm formation by Pseudomonas fluorescens

“…Lactic acid (LA) is generally recognised as a safe (GRAS), environmentally friendly and low-cost chemical with a wide-spectrum antibacterial activity over a wide range of temperatures (Ning et al 2021;Tsukatani and Sakata 2022). Previous studies have demonstrated the effects of LA on the growth of microorganisms by its effects on cells, including pH reduction, disturbance of membrane transport and permeability, anion accumulation, inhibition of enzymes, cytoplasmic acidification and the specific antimicrobial effects of anionic species (Chen et al 2022;Bevilacqua et al 2023;Ji et al 2023). LA has also served as a natural compound to promote the quality of food products (Shi et al 2022).…”
