Nov 1, 2023 · Biohydrogen production yields attained from UCM were compared to those reported in other fermentation studies, where animal manure was used as the feed for biohydrogen production (Table 3). There are only a limited number of studies conducted at elevated temperatures (T > 50 °C).
Jul 1, 2022 · If 90% of manure (144 t/d) is collected and used for MCCA production adopting this two-stage co-fermentation system, then 128.2 t corn stalk silage (30%VS, C:N ratio of 50) is required to adjust the C/N ratio of 35:1, that is, 272.2 t/d substrate is fed into this system.
Apr 1, 2024 · Dark fermentation of caw manure was optimized via pre-treatments and co-fermentation. • RSM can be applied to dark fermentation process to optimize the release of carbohydrates. • The pretreatment of H 2 O 2 combined with sonification enhances biohydrogen production. • The co-fermentation of cheese whey and cow manure resulted in higher H
Anaerobic fermentation technology could produce biogas from the organic matters derived from manure by the metabolic activity of microorganisms, and it was recommended as the recycling method for manure treatment in China [3].
Sep 1, 2021 · Co-anaerobic fermentation (co-AF) of swine manure (SM) and apple waste (AW) has been proved to be beneficial for lactic acid (LA) production. In order to further improve the LA production, three important parameters, namely AW in feedstock, temperature, volatile solids (VS) of feedstock, were evaluated using Box-Behnken design and response surface methodology.

Nov 11, 2022 · Abstract. : Acidogenic fermentation of chicken manure (CM) for production and recovery of volatile fatty acids (VFA) is an interesting biological waste-to-value approach compared to benchmark organic waste management strategies.
Abstract. Biohydrogen fermentation using liquid swine manure as substrate supplemented with glucose was investigated in this project. Experiments were conducted using a semi-continuously-fed fermenter (8 L in total volume and 4 L in working volume) with varying pHs from 4.7 through 5.9 under controlled temperature (35 ± 1 °C).
Sep 1, 2021 · In order to explore the effects of adding biochar on biogas production by high solid concentration anaerobic fermentation of livestock and poultry manure and agricultural safety, this study used pig manure, cow manure and chicken manure as fermentation raw materials, and carried out experiments on biogas production by mesophilic temperature anaerobic fermentation with high solid concentration.
May 5, 2023 · The aim of this study was to investigate the biogas production performance of an integrated microbial electrolysis cell and anaerobic reactor system (MEC-AR) treating cattle manure at different applied voltages and hydraulic retention times (HRT) ranging from 6 days to 1 day. The MEC-AR system was operated in semi-continuous mode under various voltage applications of 0.3, 0.6, and 1.0 V and
May 5, 2023 · The objective of this work was to determine the potential of chicken manure as a substrate for biogas production after pretreatment. The effects of removing excess nitrogen from chicken manure by water extraction in a temperature range from 20 °C to 60 °C to increase methane production were investigated. The dynamics of the process and efficiency of biogas production were also analyzed. As a
Dec 1, 2020 · The PHBV pilot facility was designed to produce PHBV-rich biomass from dairy manure using the standard three-stage process (fermentation, enrichment, and production; Serafim et al., 2008). As the names imply, the fermenter fermented the dairy manure to produce a VFA-rich substrate.
The solid digestate obtained from the high solid anaerobic digestion through a garage-type dry fermentation system using high-density bundled rice straw and swine manure was a value-added by-product that could be used as growth medium in seeding production.
