2021/9/1/ · Food waste was a superior bioresource for caproate production. Considering this amount of glucose, about 57.3 kg ethanol was produced in the ethanol fermentation system, which was then separated into two parts: (1) 21.3 kg ethanol is used for acetate production; and (2) 38.9 kg ethanol was used as ED for caproate production. ...

2020/1/1/ · Based on this analysis, the performance of electro-fermentation hydrogen production from food waste dark fermentation effluent and energy recovery using MECs were investigated on the macro- and micro-scales. The metabolic pathways of the sequential system combining dark fermentation with electro-fermentation hydrogen production

2023/11/1/ · With the fermentation process, the microbial diversity of FW changed significantly. According to the measurement of the Shannon index, the community diversity decreased in 0–6 d (from 1.98 to 1.56) and increased in 6–10 d (from 1.56 to 3.41) (Fig. 3 a).At the early stage of fermentation, the growth of microorganisms may be inhibited by

2022/10/1/ · The main compositions of the pretreated food waste were carbohydrate 5.94 ± 0.27 g, protein 2.51 ± 0.14 g, and lipid 2.12 ± 0.11 g per 100 g of food waste, respectively. The liquid from FW fermentation during the long-term experiment was utilized as carbon source, replacing 112 Van Niel's Yeast Agar medium as the substrate used for

2021/10/1/ · Food waste is generated daily in a huge quantity in every megacity, and biogas slurry is an easily available and intractable wastewater in food waste treatment plants. During food waste fermentation, the addition of biogas slurry promoted the production of lactic acid because it increased the pH values, maintained low OPR,

2018/1/1/ · The US ethanol plants primarily use corn as the feedstock, accounting for 95% of the total production while only 1% of the total bioethanol produced comes from food and beverage waste as shown in Fig. 5.3.In 2016, 38% of the total corn grown in the United States was utilized for ethanol production which is threefold higher compared to 12.4% in

2024/4/1/ · Nevertheless, the test run at the highest OLR had to be interrupted after a few weeks of operation, to allow for the system recovery. Adjusting organic load as a strategy to direct single-stage food waste fermentation from anaerobic digestion to chain elongation. Processes, 8 (2020), pp. 1-18.

2008/7/1/ · A field pilot-scale fermentation system was designed and built. This fermentation system was effective for the digestion of food waste and the production of methane. The tCOD removal efficiency and methane yield were estimated to be 90.1% and 254 l CH 4 /kgCOD degraded, respectively. These results were experimentally

2013/1/1/ · Highlights Three-stage (lactate- + photo-H 2 + CH 4) fermentation system treating food waste. First fermenting food waste to lactate, rather than acetate and butyrate. Lactate fermented effluent was used for H 2 production by photo-fermentation. 41% and 37% of the energy content in food waste into H 2 and CH 4, respectively. H 2

2015/9/15/ · The food waste vacuum fermentation system consisted a 2-L fermentation flask, a vacuum pump, a condensation system with a chiller and a coiled condenser and a cold-water trap. During the vacuum application, ABE and water vapors evaporated from the fermentation broth and condensed in the condensation system.

2021/7/12/ · Fermentation is the transformation of food by microorganisms, and this process can be used to help manage waste by preserving the nutritional value of fresh ingredients, repurposing food waste

2020/10/10/ · The present study focused on the integration of the non-sterile conversion of food waste (FW) into hydrogen (H 2) through dark fermentation with the subsequent electricity generation in a proton-exchange membrane fuel cell (PEMFC), and the assessment of the global warming potential (GWP) of the process.The acidogenic

2024/5/1/ · It is imperative to note that lactic acid-type fermentation liquid (LAFL) markedly differs from VFA-rich fermentation liquid. During the fermentation process of food waste, lactic acid is preferentially produced during glycolysis due to its lower Gibbs free energy requirement compared to VFA (Holtzapple et al., 2022, Zhou et al., 2018).

2021/10/1/ · To solve the problem of acidification during high-load anaerobic digestion of food waste, the effects of adding Fe 0 on acidified fermentation system were investigated. Four adding Fe 0 groups and four control groups were set under different inoculum-to-substrate ratios (ISRs) of 1.00, 0.80, 0.65, and 0.50. Results showed that adding Fe 0
