Modelling hydrogen partial pressure change as a result of competition between the butyric and propionic groups of acidogenic bacteria
TLDR
It was shown that competition between hydrogen-producing and hydrogen-utilising acidogenic bacteria for glucose causes a hydrogen partial pressure decrease at a decrease of feed flow rate.About:

Fermentative Hydrogen Production From Wastewater and Solid Wastes by Mixed Cultures
Chenlin Li,Herbert H. P. Fang +1 more
TL;DR: In this paper, over 160 publications related to fermentative hydrogen production from wastewater and solid wastes by mixed cultures are compiled and analyzed, including pre-treatment conditions for screening hydrogen-producing bacteria from anaerobic sludge or soil, and the process and performance parameters for (2) single substrates in synthetic wastewaters, (3) actual wastewater, and (4) solid wastes.

Hydrogen production from food waste in anaerobic mesophilic and thermophilic acidogenesis
TL;DR: The amount of hydrogen production from the thermophilic acidogenic culture was much higher than that from the mesophilic culture at all tested pH because of the methane free condition and negligible propionate production, and increase of VS concentrations from 3 to 10 g VS l −1 resulted in the increase of quantity and quality of hydrogenProduction.

Homoacetogenesis during hydrogen production by mixed cultures dark fermentation: Unresolved challenge
TL;DR: Genetic studies investigating blocking H2 consuming pathways and enhancing H2 evolving hydrogenases are suggested towards controlling homoacetogenesis during dark fermentation and incorporating radioactive labeling technique in H2 fermentation research could provide information on simultaneous production and consumption of H2 duringdark fermentation.

Conversion processes in anaerobic digestion
TL;DR: In this article, six different conversion processes are identified in the degradation of particulate organic material (biopolymers) to methane, and the kinetic data are applied to the design of an anaerobic digester for raw domestic sludge.

Kinetics of anaerobic treatment: A critical review
TL;DR: The fundamentals of microbial kinetics and continuous culture models are presented and the effect of temperature and inhibitors on the intrinsic kinetic rates is discussed, and Stoichiometric and bioenergetic considerations are reviewed.
Solubilization of particulate organic carbon during the acid phase of anaerobic digestion
J.A. Eastman,J.F. Ferguson +1 more
TL;DR: In this article, the acid phase of anaerobic digestion of sewage sludge was investigated and pH had a greater effect on the process than did influent solids concentrations, suggesting that digestability can be improved for highly variable feed sludges by separate phase digestion for acid production and CH/sub 4/ production.

Kinetics of Anaerobic Treatment
TL;DR: It is concluded that with but few exceptions, the evidence for the significance of mass transfer effects in the different reactor configurations is circumstantial and, in some cases, contradictory.

Mathematical Modelling of the Anaerobic Digestion Process: Regulatory Mechanisms for the Formation of Short-Chain Volatile Acids from Glucose
TL;DR: A model of the anaerobic digestion process is presented which attempts to explain the complex patterns of volatile acid production in the an aerobic digestion process using mathematical expressions derived from the known redox potential of the NAD/NADH couple.
