putrefaction The natural decomposition of dead organic matter, in particular the anaerobic decomposition of its protein by bacteria and fungi. This process produces foul-smelling substances such as ammonia, hydrogen sulfide, and organic sulfur compounds. The amino-acid nitrogen of the protein is recycled by incorporation in the bacteria and fungi.
