The Antifungal Efficacy of Extracts Derived from Kimchi Filtrates

Secondary metabolites in the culture filtrates of lactic acid bacteria offer varied chiral moieties, making them a valuable resource for drug design scaffolding. Our previous methodology included using a combination of anion exchange resins, Amberlite IRA-67 and Purolite A420S, to purify significant quantities of Lactobacillus plantarum LBP-K10 peptidyl compounds. However, current experimental evidence regarding the impact of native culture extracts and/or filtrates on pathogenic fungi in vivo/in vitro is insufficient. This study analyzed the antifungal properties of two different probiotic cultures: the CH2Cl2-extracted filtrate of Chinese cabbage kimchi (CH2Cl2-extracted CCKWLB and CH2Cl2-extracted CCKWOLB) and the non-extracted filtrate of Chinese cabbage kimchi (non-extracted CCKWLB and non-extracted CCKWOLB). The samples were divided into two groups: one group was inoculated with probiotics while the other group remained non-inoculated. Filtrates from both experimental groups were utilized for antifungal assays. The treatments employing CCKWLB, with an initial inoculation of Lb. plantarum LBP-K10 as a starter, demonstrated significant antifungal activity under various experimental conditions. Our study offers new perspectives on the antifungal properties of CH2Cl2-extracted kimchi filtrates, which are naturally produced by lactobacilli. The efficacy of antifungal compounds is supported by substantial evidence demonstrating their efficient uptake by cells and the antifungal properties exerted by metabolites.
