“…This may be due to plasma‐induced fatty acid peroxide formation and plasma charge accumulation on the surface of the outer membrane, resulting in the destruction of membrane lipids. [ 31 ] PAW was thought to damage the outer membrane in some way, making it easier for ROS and RNS to enter E. coli .…”

The plasma‐activated water (PAW) produced by low‐temperature plasma (LTP) was applied to this research because of its safety and no thermal damage. Therefore, the physicochemical properties of PAW, as well as the efficacy and sterilization mechanism of Escherichia coli, were discussed. The PAW (pH 1.27, conductivity 6400 μS/cm) could reduce E. coli by 1.31‐log reduction using LTP at 70 W for 9 min. The results demonstrated that PAW caused DNA and protein leakage with malondialdehyde production. This study may provide a basis for the theoretical research of PAW sterilization. As an effective sterilant, PAW would be a promising alternative strategy for cleaning of E. coli from pipes and filters in food factories.

“…Bacterial growth is the coordinated sum of a series of complex processes, including chemical synthesis, assembly, polymerization, biosynthesis, and transport. The activity of bacterial growth is affected by temperature [ 34 , 35 ]. The variation of bacterial growth rate with temperature is a complex process, and the Arrhenius equation suggests that the maximum specific growth rate of bacteria is temperature-dependent [ 36 ].…”

Plaque biofilms play critical roles in the development of dental caries. Mechanical plaque control methods are considered to be most effective for plaque removal, such as brushing teeth or using flosser. Recently, water flosser has been paid much attention. Here, we tested the ability of a water flosser to remove the adhered sucrose and the dental plaque biofilms formed by Streptococcus mutans, Streptococcus sanguinis, and Actinobacillus viscosus. We found that the residual sucrose concentration was 3.54 mg/mL in the control group, 1.75 mg/mL in the syringe group (simulating the ordinary mouthwash), and 0 mg/mL in water flosser group. In addition, the residual bacterial concentration was 3.6 × 108 CFU/mL in the control group, 1.6 × 107 CFU/mL in the syringe group, and only 5.5 × 105 CFU/mL in the water flosser group. In summary, water flosser is effective for cleaning the teeth, which may have significant potential in preventing dental caries and maintaining oral health.

SummaryAlicyclobacillus acidoterrestris is a typical endospore‐forming microorganism, whose spores are able to germinate in Not From Concentrate juice causing its spoilage. In this work, Dielectric Barrier Discharge Atmospheric cold plasma (DBD‐ACP) at the voltage of 30 kV was used to inactivate Alicyclobacillus acidoterrestris spores in NFC juice (2‐8 min). The results showed spores reduced nearly 3‐log CFU/mL after 8 min treatment, and the morphology of spores were severely disrupted, causing the release of their contents. Furthermore, proteomic analysis showed totals of 122 and 170 different expression proteins were detected in group C (control)/Ct1 (30 kV, 4 min) and C/Ct2 (30 kV, 8 min), respectively, indicating that metabolic activities of spores including amino acid and energy metabolic, protein biosynthesis, DNA replication and spore germination are inhibited, This study confirms the inactivation of Alicyclobacillus acidoterrestris spores by DBD‐ACP and provides some new perspectives on the inactivation mechanisms of spores by DBD‐ACP.
