Summary: Hydrogen (H-2) is an important electron donor for microbial processes in the environment, but the total H-2 demand of soils is generally unknown. This study measured the H-2 demand of different geochemically diverse soils and identified the processes leading to this demand. The results showed a wide range of H-2 demand in soils, greatly exceeding the theoretical demand predicted based on initial concentrations of electron acceptors. Methanogenesis accounted for the largest fraction of H-2 demand, but humic acid reduction and acetogenesis were also significant H-2-consuming processes. The total organic carbon content of soils showed the strongest correlation to H-2 demand.

Summary: Pretreatment of municipal sludge has the potential to improve anaerobic digestion and increase methane production. However, the increased soluble COD from pretreatment makes it difficult to estimate hydrolysis kinetics accurately. In this study, batch digestion tests were conducted to evaluate the impact of alkaline and thermal pretreatment and to determine a different method to estimate hydrolysis rates. The inclusion of semi-soluble COD and volatile fatty acids in the hydrolysis kinetics model improved the accuracy of estimating the hydrolysis rates of pretreated solids.
