Anaerobic bulking-associated microbiota occurred in a mesophilic expanded granular sludge bed reactor treating high-strength organic wastewater discharged from a food-processing manufactory based on 16S rRNA gene amplicon data. sludge metagenome

16S rRNA amplicon sequencing with DNA extracted from bulking and healthy sludge granules were performed to gain insight into the ecological information on microbial communities in a mesophilic expanded granular sludge blanket treating wastewater discharged from food-proccessing manufactory.
