Abstract
- Makgeolli, a traditional Korean liquor, contains components such as lactic acid bacteria and dietary fiber, which can induce changes in the gut microbiome. Since variations in microbiome responses may exist between enterotypes-classifications based on the dominant bacterial populations in the gut-we hypothesized that the consumption of makgeolli leads to enterotype-dependent differences in gut microbial structures among healthy participants. This study aimed to determine the effect of makgeolli consumption on gut microbial structures by stratifying all participants into two enterotype groups: Bacteroides-dominant type (B-type, n = 7) and Prevotella-dominant type (P-type, n = 4). The B-type showed an increase in alpha diversity, while no significant difference was observed in the P-type following makgeolli consumption. The composition of gut microbiota significantly changed in the B-type, whereas no noticeable alteration was observed in the P-type after makgeolli consumption. Notably, Prevotella exhibited the most significant changes only in the P-type. In line with the increased abundance of Prevotella, the genes associated with carbohydrate metabolism, including pentose/glucuronate interconversions, fructose/mannose metabolism, starch/sucrose metabolism and amino sugar/nucleotide sugar metabolism were significantly enriched following makgeolli consumption in the P-type. These findings suggest that makgeolli consumption induces enterotype-dependent alterations in gut microbial composition and metabolic pathways, highlighting the potential for personalized dietary interventions.
