Abstract

This chapter presents a systematic study of the inhibition effect of chlorine dioxide treatment alone and in combination with ultrasound treatment of Salmonella and the physiological metabolic processes within the treated cells. The low-power ultrasound (0.03 W/mL) significantly enhanced the effectiveness (110.00 %) of low concentrations of chlorine dioxide (0.25 mg/L) in inhibiting Salmonella, which, in turn, would significantly reduce the potential environmental impact. In addition, further studies found that low-power ultrasound may enhance the structural and functional damage of chlorine dioxide on Salmonella cell membranes (significant increase in permeability of the outer and inner cell membranes) and disrupt intracellular substance metabolism (small molecule and nucleotide metabolism) and energy metabolism (significant reduction in ATP content and ATPase activity) balance to improve the bacterial inhibitory effect of chlorine dioxide. The results of the study will provide a theoretical basis and methodological guidance for the implementation of \"cleaner production\" in the food industry.

摘要

本章对单独使用二氧化氯处理以及与超声波联合处理沙门氏菌的抑制作用以及处理细胞内的生理代谢过程进行了系统研究。低功率超声(0.03W/mL)显著提高了低浓度二氧化氯(0.25mg/L)抑制沙门氏菌的有效性(110.00%),which,反过来,将大大减少潜在的环境影响。此外,进一步研究发现,低功率超声可增强二氧化氯对沙门氏菌细胞膜的结构和功能损伤(细胞膜内外通透性显著增加),破坏细胞内物质代谢(小分子和核苷酸代谢)和能量代谢(ATP含量和ATP酶活性显著降低)的平衡,提高二氧化氯对细菌的抑制作用。研究结果将为食品工业实施“清洁生产”提供理论依据和方法指导。
