2023/8/1/ · Food waste (FW) has been recognized as essential reservoir for resource recovery via anaerobic fermentation, which could also bring the potential risk of antibiotic resistance genes (ARGs) dissemination. Although the structural deficiency of FW could be stimulated by enzymatic pretreatment to enhance fermentation efficiency, the influences
2022/2/1/ · According to the different metabolites and pathways of LAB fermentation, LA fermentation can be divided into homo-lactic acid metabolism and hetero-lactic acid metabolism (Wang et al., 2015b), while hetero-lactic acid metabolism can be divided into the hexose monophosphate pathway (HMP) and hexokinase (HK) pathway.In homo-lactic
2021/8/17/ · A third of food produced globally is thrown out, but an article in Forbes explores a promising solution — more companies are using fermentation as a way to decrease food waste. A new Danish startup, Resauce, gives companies the resources to turn their food waste into fermented products. Their success stories include a farmer
2022/9/1/ · Food waste fermentation produces ethanol as well as various other value added products such as enzymes but in case of composting and anaerobic digestion similar end product is obtained such as methane or biogas Depending on the literature, the functional unit represented in this study varies e.g., it can be 1 L of ethanol, 1 MJ of
2024/4/15/ · The food waste inflow into the anaerobic digestion system is 41,666 kg·h −1, where food waste undergoes conversion to CO 2 and CH 4 at rates of 2,655 kg·h −1 and 1,660 kg·h −1, respectively. The generated CO 2 and CH 4 are utilized in fermentation to produce biomass, from which 1,324 kg·h −1 lipid can be extracted, serving as the
2009/9/7/ · The H 2 production and carbohydrate removal in heat-treated, acid-treated, alkali-treated, and untreated food wastes are presented in Table 3.In all cases, CH 4 was not detected during the whole fermentation period. H 2 production rate and lag-phase time for the heat-treated, the acid-treated, and the untreated food wastes were derived using
2019/10/8/ · This work aimed to investigate the effects of supplementing two distinct types of ash, namely fly ash (FA) and bottom ash (BA) on the dark fermentation (DF) process of food waste (FW) for H 2 production. Both types of biomass combustion ash (BCA) were collected in an industrial bubbling fluidized bed combustor, using residual
2022/2/1/ · The food waste was pretreated by wet degreasing for 80 min and centrifuged at 120 °C with 6000 r/min. Sodium butyrate was used as a carbon source for the enrichment of BRM. The physicochemical parameters of the fermentation material in the BRM enrichment and acidification regulation stages are shown in Table 1 .
2024/2/20/ · Furthermore, in practice, the content of alcohols and acids is not solely determined by the components of food waste. For instance, Feng et al. (2018) found that the primary component in the food waste fermentation broth is lactic acid when the pH ranges from 3.2 to 4.5. However, when the pH is between 4.7 and 6.0, the fermentation
2020/8/11/ · Food waste can occur at every stage of the production and supply chain from farming, processing, and consumption. According to the USDA, in the United States, approximately 31% (133 billion pounds) of the overall food supply goes uneaten through loss or waste. This increased waste stream not only impacts food security, but directly harms
2019/8/9/ · Solid-state fermentation (SSF) is, by definition, a technology carried out in absence or near absence of free water. Therefore, it allows the use of solid materials as substrates for further biotransformation. SSF has gained attention in the last years being reported as a promising eco-technology that allows obtaining bioproducts of industrial
2021/1/1/ · Food waste can turn to bio-resource for fermentation through hydrolysis treatment. The reported pretreatment have different nature of processes, hence posted different cost of operation. Table 1 shows the cost distribution of three different pretreatment that operate under the optimal conditions.
2023/12/1/ · Zhu et al. reported that the highest ethanol yield of food waste reached about 22000 mg COD/L by controlling the pre-fermentation pH of 4.0–4.5 for 4 days, accounting for 8.9% of the influent COD of the methanogenic reactor (Zhu et al., 2022). It should be noted that ethanol fermentation at the pH of 4.0–4.5 takes a few days, which
2023/7/22/ · Solid-state fermentation is a tool that allows the development of microorganisms on solid or semisolid substrates in the absence of free water. This particularity allows agro-food waste to be used as fermentation substrates to generate various products such as the release of bioactive compounds, enzyme production, waste …
