• A comprehensive survey of bacterial and archaeal community structures within granular sludges taken from twelve different types of full-scale, food-processing wastewater-treating, upflow anaerobic sludge blanket (UASB) reactors was performed with a 16S rRNA gene-based clone library method. In total, 1,282 bacterial 16S rRNA gene clones and 722 archaeal clones were analyzed, and their identities were determined by phylogenetic analyses. Overall, clones belonging to the bacterial phyla Proteobacteria (the class Deltaproteobacteria in particular), Firmicutes, Spirochaetes, and Bacteroidetes were observed in abundance within the bacterial clone libraries examined, indicating common bacterial denominators in such treatment systems. Within the domain Archaea, clones affiliated with the classes Methanomicrobia and Methanobacteria were found to be abundant in the archaeal libraries. In relation to features of reactor performance (such as chemical oxygen demand removal, fatty acid accumulation, and sludge bulking), possible representative phylotypes likely to be associated with process failures, such as sludge bulking and the accumulation of propionate, were found in comparative analyses of the distribution of phylotypes in the sludge libraries.
