Microbial diversity of traditional Korean alcoholic beverages
Makgeolli is a traditional Korean alcoholic beverage manufactured with a natural starter, called nuruk, and grains. Nuruk is a starchy disk or tablet formed from wheat or grist containing various fungal and bacterial strains from the surrounding environment that are allowed to incorporate naturally into the starter, each of which simultaneously participates in the makgeolli fermentation process. In the current study, changes in microbial dynamics during laboratory-scale fermentation of makgeolli inoculated with six different kinds of nuruk were evaluated by barcoded pyrosequencing using fungal- and bacterial-specific primers targeting the internal transcribed spacer 2 region and hypervariable regions V1 to V3 of the 16S rRNA gene, respectively.
