Abstract

The theory of interspecies hydrogen transfer (Wolin and Miller, 1982) is now nearly two decades old, and is considered the biochemical cornerstone of methanogenesis in all natural and man-made habitats (soils, sediments, intestines; anaerobic digesters and treatment systems). Therefore, it is surprising that only a handful of engineering studies (Table 1) have focused on the production and effects of hydrogen during continuous treatment of various waste substrates. A review of this information reveals: 1) a lack of consensus on the inhibitory effects of hydrogen, and 2) an insufficiency of information to allow generalization of interspecies hydrogen effects under all possible treatment scenarios (i.e., all combinations of reactor configuration and wastewater type).
