Quantifying the percentage of methane formation via acetoclastic and syntrophic acetate oxidation pathways in anaerobic digesters.
Ammonia concentration is one of the key factors influencing the methanogenic community composition and dominant methanogenic pathway in anaerobic digesters. This study adopted a radiolabelling technique using [2-14C] acetate to investigate the relationship between total ammonia nitrogen (TAN) and the methanogenic pathway. The radiolabelling experiments determined the ratio of 14CO2 and 14CH4 in...
متن کاملMethanosarcinaceae and acetate-oxidizing pathways dominate in high-rate thermophilic anaerobic digestion of waste-activated sludge.
This study investigated the process of high-rate, high-temperature methanogenesis to enable very-high-volume loading during anaerobic digestion of waste-activated sludge. Reducing the hydraulic retention time (HRT) from 15 to 20 days in mesophilic digestion down to 3 days was achievable at a thermophilic temperature (55°C) with stable digester performance and methanogenic activity. A volatile s...
متن کاملEnergy conservation in syntrophic acetate oxidation
Background: Thermacetogenium phaeum is a thermophilic strictly anaerobic bacterium oxidizing acetate to CO2 in syntrophic association with a methanogenic partner. It can also grow in pure culture, e.g., by fermentation of methanol to acetate. The key enzymes of homoacetate fermentation (Wood-Ljungdahl pathway) are used both in acetate oxidation and acetate formation. The obvious reversibility o...
متن کاملThermodynamic constraints on syntrophic acetate oxidation.
Syntrophic acetate oxidation coupled to hydrogenotrophic methanogenesis has been identified as a significant anaerobic pathway in high-temperature (55°C) oil fields (1, 2). In a paper on acetate production from oil under sulfate-reducing conditions, Callbeck et al. (3) took note of that observation, only to emphatically state that “syntrophic acetate oxidation coupled to hydrogenotrophic methan...
متن کاملMathematical Modelling of the Anaerobic Digestion Including the Syntrophic Acetate Oxidation
Anaerobic digestion is an effective biotechnological process for treatment of different agricultural, municipal and industrial wastes. However, it is a very unstable process in regard to the biogas reactors operation. This is due to the complicated interactions between different microbial species as well as of the complex transformations of the organic matter affected by a variety of environmen...
