In space, fermentation could be leveraged to repurpose food waste for a closed-loop system, preserve limited fresh ingredients, diversify food selection, grow nutrients, and

In case of anaerobic fermentation, no aeration device is needed as the gases generated during the process enable satisfactory mixing. The environment inside the vessel needs to be maintained oxygen scarce during the whole process which is maintained by flushing a mixture of CO2, H2 and N2 in the head space of the fermenter.

2011/11/17/ · The estimated cost of producing 99.9% H 2 was CNY 1.37 per cubic meter. The hydrogen produced was used to generate electricity via fuel cells. The effluent from the process was used for fermentative methane production followed by a wastewater treatment process. The final effluent met the national discharge standards.

2023/5/2/ · 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

2022/10/13/ · The Type L fermenter is constructed as a partially in-ground concrete earthen basin, whereas the Type S reactor is constructed in a space-saving above ground concrete or steel tank. The Bulk Volume Fermenter operates at a very long solids retention time, up to 90 days, which provides greater digestion and stability than other anaerobic

2023/11/17/ · Chitin is one of the most abundant polymers in nature, with chitinous biomass often discarded as food waste and marine debris. To explore an effective way to degrade chitin, in this work, anaerobic sludge was inoculated at the anode of a two-chamber microbial fuel cell (MFC), and chitin was degraded via anaerobic respiration and

2012/9/1/ · Anaerobic fermentation to produce biogas is a microbial-driven process, with various species acting in different stages of the conversion of input material into biogas. Raw biogas is not suitable for commercial purposes due to the presence of contaminants, requiring purification and upgradation to reach maximum calorific value.

2022/3/3/ · Despite the importance of the biodegradability of lignocellulose biomass, few studies have evaluated the lignocellulose biomass digestion kinetics and modeling of the process. Anaerobic digestion (AD) is a mature energy production technique in which lignocellulose biomass is converted into biogas. However, using different organic waste

2024/1/29/ · The objective of this paper is to gain insights into the synergistic advantage of anaerobic co-fermentation of heat-treated sludge (HS) with food waste (FW) and heat-treated food waste (HFW) for

2022/4/1/ · In summary, the MEC system can significantly promote the traditional anaerobic fermentation, while the application of MEC can improve the utilization rate of the substrate, shorten the time required for fermentation, and increase the yield and purity of methane. At the same time, through the analysis of the energy balance in the reaction

Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that's performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end. Fermentation and cellular respiration begin the same way, with glycolysis.

2024/3/15/ · Anaerobic fermentation is an effective method to harvest volatile fatty acids (VFAs) from waste activated sludge (WAS). Accurately predicting and optimizing VFAs production is crucial for anaerobic fermentation engineering. It involves partitioning the dataset D X Y in the two-dimensional space into a grid G consisting of n x rows and n y ...

2017/5/3/ · Membrane bioreactor systems can enhance anaerobic lactic acid fermentation by reducing product inhibition, thus increasing productivity. In batch fermentations, the bioconversion of glucose is strongly inhibited in the presence of more than 100 g·L −1 lactic acid and is only possible when the product is simultaneously removed,

2023/8/21/ · Polyaluminum chloride (PAC) is used widely and increasingly in wastewater treatment plants, resulting in its inevitably high production in sludge. Previous studies have indicated that the production of short-chain fatty acids (SCFAs) is inhibited by the existence of PAC in sludge anaerobic fermentation, so it is necessary to study how

2023/4/14/ · The scale-up technology of anaerobic fermentation stirring equipment is worthy of attention. Computational fluid dynamics (CFD) simulations were used to study the scale-up of anaerobic fermentation mixing under different solid content conditions. The applicability of different scale-up criteria was analyzed by investigating the relative …
