Metagenomes from the colonic contents of medicated swine
"Samples from up to 6 swine (biological replicates) were treated as follows for metagenomic library preparation:  blend 5 g material in PBS, centrifuge at 250xg to reduce plant material, then centrifuge the supernatant at 10,000g to pellet the cells, followed by bead beating the resuspended pellet for bulk DNA extraction (kit by MoBio)"
