This study aimed to evaluate three standard enrichment broth preparations for the recovery of healthy and chlorine-injured E. coli O157:H7 cells in kimchi. The growth of healthy and chlorine-injured cells in kimchi was observed in three different broths for 24 h. Results showed that the three broths were equally effective for the growth of healthy cells, although the broth described by the International Organization for Standardization (ISO) showed better performance in terms of maximum growth rate when compared to the other two broths described by the Korea Food Code (KFC) and the Food and Drug Administration (FDA). In the case of chlorine-injured cells, similar growth patterns were observed in KFC and ISO broths, whereas inhibition or no growth was found in FDA broth. Thus, this study suggests that KFC and ISO broths were more suitable than FDA broth for the enrichment of E. coli O157:H7 cells in kimchi.

本研究旨在评估三种标准的富集肉汤制剂，用于恢复健康和受氯损伤的大肠杆菌。泡菜中的 O157:H7 细胞。在三种不同的肉汤中观察了泡菜中健康细胞和氯损伤细胞的生长 24 小时。结果表明，三种肉汤对健康细胞的生长同样有效，尽管与韩国食品公司描述的其他两种肉汤相比，国际标准化组织 (ISO) 描述的肉汤在最大生长率方面表现出更好的性能Code (KFC) 和食品和药物管理局 (FDA)。在氯损伤细胞的情况下，在肯德​​基和 ISO 肉汤中观察到类似的生长模式，而在 FDA 肉汤中发现抑制或没有生长。因此，这项研究表明，肯德基和 ISO 肉汤比 FDA 肉汤更适合富集泡菜中的大肠杆菌O157:H7 细胞。
