16S rRNA amplicon sequencing of microbial communities in a bulking and healthy sludge granules in a mesophillic expanded granular sludge bed reactor

16S rRNA amplicon sequencing with DNA extracted from bulking and healthy sludge granules were carried to gain insight into the ecological information on microbiota in a mesophilic expanded granular sludge blanket treating wastewater discharged from beverage-producing manufactory.
