Identified CAZymes: Heat maps of all identified a glycoside hydrolases, b carbohydrate esterases, c polysaccharide lyases, and d glycosyl transferases in the metagenomes from the anaerobic digesters (ADs) Søholt, Randers, Viborg, and Fredericia. The enzyme families are listed on the right side and named according to the Carbohydrate-Active Database (http://www.cazy.org). The heat maps are calculated individually for each AD and enzyme families with no identified members in any of the metagenomes are not shown
