title: Metagenome of aerobic granular sludge from GSBR 12 h
design: DNA isolation was done using a FastDNA SPIN Kit for Soil (MP Biomedicals). The quality and quantity of the DNA was analyzed with a Lite NanoDrop spectrometer (Thermo Scientific). A 926F/1392R universal primer set  targeting Bacterial and Archaeal 16S rDNA gene was used for amplification and the amplicons were sequenced using the MiSeq Illumina platform in Research and Testing Laboratory (USA).
