Improvement of Wastewater Treatment Performance and Power Generation in Microbial Fuel Cells by Enhancing Hydrolysis and Acidogenesis, and by Reducing Internal Losses

Energies, 2018
In this study, biodegradation performance and power generation in MFCs were improved. Domestic wastewater was biodegraded in a dual-chamber MFC system equipped with a DupontTM Nafion® 117 proton exchange membrane, graphite electrodes (8.0 cm × ...

Acidogenesis of dairy wastewater at various pH levels

Water Science and Technology, 2002
Continuous experiments were conducted to study the influence of pH in the range 4.0–6.5 on the acidification of dairy wastewater at 37°C with 12 hours of hydraulic retention in an upflow reactor. Results showed that degradation of dairy pollutants increased with pH from pH 4.0 to 5.5. At pH 5.5, 95% of carbohydrate, 82% of protein and 41% of lipid were

Acidogenesis in Relation to In-Reactor Granule Yield

Water Science and Technology, 1992
A systematic study of in-reactor granule yield data was set up in the laboratory. Methanogenic granular sludge growth in fed batch shake flasks for different substrates appeared to decrease with the energy content of the substrate and required the presence of a mixing force.

Effect of Aso limonite on anaerobic digestion of waste sewage sludge

AMB Express, 2020
The effect of Aso volcanic limonite was explored in anaerobic digestion using waste sewage sludge (WSS). In this study, methane and hydrogen sulfide were remarkably inhibited when Aso limonite was mixed with WSS as well as a significant reduction of ...

Evaluation of acidogenesis products’ effect on biogas production performed with metagenomics and isotopic approaches

Biotechnology for Biofuels, 2021
Background During the acetogenic step of anaerobic digestion, the products of acidogenesis are oxidized to substrates for methanogenesis: hydrogen, carbon dioxide and acetate. Acetogenesis and methanogenesis are highly interconnected processes due to the

Effect of Sulfate Reduction on the Acidogenesis of Sucrose.

Journal of Japan Society on Water Environment, 1995
Effects of COD/S ratio and hydraulic retention time (HRT) on the degradation of sucrose in acidogenic phase were evaluated by using anaerobic chemostat at 35°C. The COD/S ratio and HRT were changed in the range of 13 to 3,500 (control) and 2 to 10h, respectively.

Acidogenesis of Pentose Liquor to Produce Biohydrogen and Organic Acids Integrated with 1G–2G Ethanol Production in Sugarcane Biorefineries

Waste, 2023
Second-generation (2G) ethanol production has been increasingly evaluated, and the use of sugarcane bagasse as feedstock has enabled the integration of this process with first-generation (1G) ethanol production from sugarcane. The pretreatment of bagasse

Autophagy is important to the acidogenic metabolism of Aspergillus niger.

PLoS ONE, 2019
Significant phenotypic overlaps exist between autophagy and acidogenesis in Aspergillus niger. The possible role of autophagy in the acidogenic growth and metabolism of this fungus was therefore examined and the movement of cytosolic EGFP to vacuoles ...

Modeling Physiological Differences in Cell Populations: Acetone-Butanol-Ethanol (ABE)-Fermentation in a Cascade of Continuous Stirred Tank Reactors

Chemical Engineering Transactions, 2016
Acetone-Butanol-Ethanol (ABE)-fermentation with Clostridium acetobutylicum is a biphasic fermentation process. The formation of organic acids in the so called acidogenesis has to precede the economically interesting phase of solvent formation called ...
