Characterization of Lactobacillus plantarum strains isolated from black raspberry and their effect on BALB/c mice gut microbiota

Abstract

The objective of this study was to evaluate probiotic effects of two Lactobacillus plantarum strains (GBL16 and 17) isolated from black raspberry. Results revealed that the number of GBL16 was gradually decreased as bile salt concentration was increased from 0.3 to 1%. However, GBL17 did not show any difference when GBL17 was applied to 1% bile salt, and it indicates that GBL17 is more tolerant to bile salt than GBL16. GBL17 exhibited higher heat resistance and adhesion ability to Caco-2 cells than GBL16. Regarding gut microbiome, no significant change in the number of total bacteria in intestines of mice after treatment with GBLs was determined. However, the combination of GBL16 and GBL17 significantly increased the number of total bacteria in intestines of mice after they were orally administered. Therefore, the results suggest that both GBL16 and 17 strains could be one of major probiotics that can improve human gut health.

Probiotic Properties and Antioxidant Activities of Pediococcus pentosaceus SC28 and Levilactobacillus brevis KU15151 in Fermented Black Gamju

“…Nowadays, consumers are increasingly demanding functional foods that are rich in probiotic bacteria [ 1 , 2 ]. Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host such as immunomodulatory, antimicrobial, anticancer, and hypolipidemi effects [ 3 ].…”

In Vivo Evaluation of Immune-Enhancing Activity of Red Gamju Fermented by Probiotic Levilactobacillus brevis KU15154 in Mice

“…Recently, many people have become increasingly interested in functional foods that contain natural ingredients to maintain their health or prevent diseases [1,2] and many food scientists have eagerly studied bio-functional materials such as probiotics, phytochemicals, organic materials produced by microorganisms (fermentation or bioconversion). In particular, lactic acid bacteria (LAB) are considered the most commonly used biomaterials, as studies have shown that the LAB-mediated treatment has many benefits in illnesses, such as foodborne diseases, inflammation, intestinal diseases, and cancer [3][4][5][6].…”
