    Abstract Due to riching in polyphenolic compounds, betalains, and ascorbic acid, beetroot (Beta vulgaris) extract exhibits an antibacterial activity. However, its effect on Listeria monocytogenes is unclear. In this study, the antibacterial activity of beetroot extract against L. monocytogenes was assessed by measuring its minimum inhibitory concentration (MIC) and the time-kill curve. Results revealed that the MIC of beetroot extract against L. monocytogenes was 20 mg/mL and bacterial survival decreased as beetroot extract concentration increased. The antibacterial mechanism of beetroot extract involved the reduction of intracellular 5ʹ-adenosine triphosphate levels of L. monocytogenes after treatment. L. monocytogenes exhibiting membrane depolarization, caspase-like protein activation, phosphatidylserine externalization, and DNA fragmentation, demonstrated that L. monocytogenes underwent apoptosis-like death (ALD) following beetroot extract treatment. Furthermore, the reason of ALD in L. monocytogenes is reactive oxygen species depletion. Beetroot extract decreased the number of L. monocytogenes cells, pH values, and lipid oxidation in cooked pork. Meanwhile, cooked pork become darker and redder than the control samples. It suggested that beetroot extract could be used as a natural preservative in cooked meat production to inhibit the growth of L. monocytogenes.

    Abstract In this study, we assessed the phytochemicals of beetroot (Beta vulgaris) extract (BE), and examined the antibacterial activity and possible mechanism of BE against Bacillus cereus. The phytochemicals in BE were analyzed by UPLC-ESI-MS-based widely targeted metabolomics analysis, and identified a total of 745 phytochemicals. Nine polyphenols and 19 flavonoids with growth-inhibiting activity against B. cereus were identified. The minimum inhibitory concentration (MIC) of BE against B. cereus was 15 mg/mL. The intracellular adenosine 5'-triphosphate (ATP) levels were decreased and the B. cereus exhibited the features of apoptosis-like death (ALD) [cell membrane depolarization, caspase-like protein activation, phosphatidylserine (PS) translocation, and DNA fragmentation] by depleting reactive oxygen species (ROS) after BE treatment. These results suggest BE is rich in bioactive substances and induces ALD in B. cereus. Thus, the phytochemicals diversity makes BE as a source of bioactive ingredients, especially as a promising potential natural preservative to reduce B. cereus contamination.

    Abstract This research aimed to disclose the antibacterial activity of beetroot extract (Beta vulgaris) against Cronobacter sakazakii and its possible mechanisms. We evaluated its antibacterial activity by measuring the minimum inhibitory concentration (MIC) and time-kill kinetics. We also evaluated the intracellular ATP levels, bacterial apoptosis-like death (ALD), and reactive oxygen species (ROS) levels to reveal the possible antibacterial mechanisms. Our results showed that the MIC of beetroot extract against C. sakazakii was 25 mg/mL and C. sakazakii (approximately 8 log cfu/mL) was completely inhibited after treatment with 2 MIC of beetroot extract for 3 h. Beetroot extract reduced intracellular ATP levels and facilitated characteristics of ALD in C. sakazakii, such as membrane depolarization, increased intracellular Ca²⁺ levels, phosphatidylserine externalization, caspase-like protein activation, and DNA fragmentation. Additionally, and different from most bacterial ALD caused by the accumulation of ROS, beetroot extract reduced the intracellular ROS levels in C. sakazakii. Our experimental data provide a rationale for further research of bacterial ALD and demonstrate that beetroot extract can inhibit C. sakazakii in food processing environments.
