Analyses of archaeal communities in Doenjang and Ganjang using a culture-independent manner based on 16S rRNA sequences

Abstract

The archaeal diversity in the soybean fermented food was analysed by culture-independent methods based on the 16S rRNA sequences. The 21 doenjang archaea - clones from the doenjang library were grouped into 5 groups: uncultured archaeon clone AE34 (42.8%), uncultured archaeon clone AS17 (28.6%), uncultured compost archaeon clone 4A29 (4.8%), uncultured compost archaeon clone 0A10 (19.0%), and uncultured compost archaeon clone 5A16 (4.8%). The 21 ganjang archaea - clones from the ganjang library were grouped into 5 groups: Halophilic archaeon MH1-34-1 (19.0%), H. archaeon MH1-16-3 (61.9%), Halococcus thailandensis (4.8%), Haloplanus sp. RO5-8 (9.5%), and H. archaeon MH1-136-2 (4.8%).
