Feb 1, 2020 · DOI: 10.1016/j.wasman.2019.10.046 Corpus ID: 207895330; Kinetics of methane production during anaerobic fermentation of chicken manure with sawdust and fungi pre-treated wheat straw.
Dec 1, 2021 · Volatile fatty acid (VFA) accumulation caused by high ammonia concentrations is often encountered during the anaerobic digestion (AD) of ammonia-rich substrates. In this study, propionate-degrading methanogenic cultures were introduced to augment the semi-continuous AD of chicken manure under high ammonia levels. Introduction of a methanogenic culture enhanced the methane yield in the

May 2, 2023 · Anaerobic digestion of animal manure results in the production of renewable energy (biogas) and nutrient-rich biofertilizer. A further benefit of the technology is decreased greenhouse gas emissions that otherwise occur during manure storage. Since animal manure makes anaerobic digestion cost-efficient and further advance the technology for higher methane yields, it is of utmost importance to
Jun 22, 2024 · The Inner Mongolia Autonomous Region is a crucial area in China with a significant advantage in animal husbandry, particularly in cattle and sheep farming. However, the disposal of the large quantities of manure produced during farming has severely impacted the industry’s healthy development. Proper treatment of the manure can convert it into organic fertilizer beneficial to farmland

May 15, 2014 · DOI: 10.1016/J.CEJ.2013.11.074 Corpus ID: 83479287; Characterization of methanogenesis, acidogenesis and hydrolysis in thermophilic methane fermentation of chicken manure.
Jun 1, 2024 · Treating chicken manure (CM) through anaerobic digestion encounters a hurdle due to its high nitrogen content, leading to volatile fatty acid accumulation and methanogenesis disruption. To overcome this, redirecting the process to yield soluble metabolite products (SMPs) and hydrogen is proposed.
May 2, 2022 · The acetate was the main volatile fatty acid (VFA) produced during sole chicken manure fermentation process in the first stage. Statistical analysis revealed that hydrogen production from co-digestion process and sole food waste fermentation process followed the n-butyrate-type pathway.

The paper presents data on the study of the kinetics of gas formation from chicken manure under thermophilic conditions. It was shown that the volume of biogas for 30 days in the control variant did not exceed 85 dm3, whereas with the addition of 10 and 20% of the balanced thermophilic methanogenic association as an inoculate was 150 and 180 dm3, respectively, and the
Feb 1, 2015 · Mono-fermentation of chicken manure was successfully carried out at high ammonia concentrations. Controlled recirculation of treated liquid fraction of digestate could be a solution in large-scale application for both: to avoid ammonia inhibition and minimize digestate.
Characterization of food waste, and chicken dung Substrate for fermentation was a mixture of chicken manure, fruit and vegetables waste, in a ratio of 1:4 based on gVS (volatile solids). They dried at room temperature in the laboratory, crushed to a state of 1-2 cm. The organic carbon, COD of soluble organic components,
