2023/7/28/ · Anaerobic fermentation (AF) can effectively dispose of kitchen waste (KW) without the shortcomings of traditional such as incineration and sanitary landfill. However, KW has a high organic content, which easily leads to acidification and ammonia inhibition during digestion. To mitigate this issue, anaerobic co-digestion
2024/2/25/ · Acidogenic fermentation can convert food waste (FW) into small molecules of acids and alcohols, and the broth can be used as a carbon source of denitrification in wastewater treatment plants. However, the soluble nitrogen-containing substances generated in fermentation influence the quality of the carbon source, and

2022/4/1/ · Lignin, derived from the residues of exogenous materials (e.g., toilet tissue, vegetable remnants, leaves) in the wastewater streams, was a complex, amorphous, Triclocarban enhances short-chain fatty acids production from anaerobic fermentation of waste activated sludge. Water Res., 127 (2017), pp. 150-161.
2019/7/1/ · The regulation of two-stage caproate fermentation from fruit and vegetable waste (FVW) via anaerobic microbial consortia was investigated in this study. The results showed the highest caproate production achieved 14.9 g/L at the optimal inoculum to substrate ratio (ISR) of 2:1, ethanol to acid ratio (E/A) of 4:1, and pH of 7.5.
2024/2/20/ · Concurrently, (Rasi et al., 2022), while studying the anaerobic fermentation process of food waste from different hotels, found that the lipid content in various types of food waste did not significantly decrease before and after the reaction. In fact, the lipid content in the FW3 group increased post-reaction due to the reduction of
2021/5/1/ · In anaerobic digestion (AD) of food waste (FW), the acetogenesis stage is thermodynamically limited and often leads to acid inhibition. This study investigated the impact of optimizing ethanol pre-fermentation (EP) of FW through saccharification pretreatment (SP) on AD by regulating the acidification pathway of substrates.
2015/6/1/ · Continuous laboratory-scale experiments were conducted on two-stage anaerobic systems treating vegetable waste (VW) to improve CH 4 production. The acidogenic reactors were employed with a serial methanogenic reactor configuration with volume distribution ratios of 3 L/4 L and 3 L/7 L (acidogenic reactor/methanogenic
The study explores the effects of different pH ranges (5.5–8) and food to microorganism (F/M) ratios (0.5–2) on the H2 production from fruit and vegetable waste (FVW). The study was performed via dark fermentation of mixed FVW without temperature control. The study highlights the effect of different kinetic parameters, such as lag time (λ), maximum H2
