The chapter is from the book Trace Elements in Anaerobic Biotechnologies, Fernando G. Fermoso, Eric van Hullebusch, Gavin Collins, Jimmy Roussel, Ana Paula Mucha and Giovanni Esposito (Eds.).

This chapter provides an overview of the main biochemical transformations of major elements, including carbon, nitrogen, sulfur, iron and phosphorus in anaerobic digesters. Mineralization of organic matter during anaerobic digestion processes results in the production of inorganic carbonate, ammonium, sulfide, and phosphate species, which are involved in a complex network of chemical and biological reactions through interaction with available macro and micro nutrients as well as microbial processes with profound effects on the efficiency and stability of the anaerobic digester performance. The interplay of iron, phosphorus and sulfur cycles has recently attracted attention in the frame of research developed for the recovery of phosphorus on one hand and in the frame of the addition of iron minerals for enhancing anaerobic digester performance on the other hand. These research topics have led to the development of analytical and biogeochemical modelling tools to provide a better understanding of the fate of major elements in an anaerobic digester.
