Aug 10, 2021 · Anaerobic fermentation or digestion is a promising WAS treatment method because it can simultaneously reduce sludge mass and recycle useful bioproducts including volatile fatty acids (VFAs), alcohols, methane and hydrogen (Hu et al., 2018; Xu et al., 2020; Zhao et al., 2021).
Fermentation broth from fruit and vegetable waste (FFVW) has demonstrated remarkable ability as a soil amendment and in reducing antibiotic resistance genes (ARGs) pollution. However, the potential of FFVW to mitigate other microbial contamination such as human bacterial pathogens (HBPs) and virulence factor genes (VFGs), which are closely
Sep 15, 2023 · Simultaneously, the anaerobic biorefinery process with multiple product co-production is sorted out. Product co-production can reduce waste discharge, enhance resource recovery efficiency, and serve as a model for improving anaerobic fermentation economics.
Jan 1, 2023 · Tang et al. (2011) indicated that adding NO 3 − to a typical sludge anaerobic fermentation unit (operated at 35 °C), improved the sludge destruction effect, for which the total suspended solids (TSS) and volatile suspended solids (VSS) in simultaneous anoxic fermentation and denitrification system decreased by 63.8 % and 74.7 %, respectively.
Jan 1, 2019 · Sludge dark fermentation generally contains several processes: disintegration, hydrolysis, acidogenesis, acetogenesis, homoacetogenesis, methonogenesis, and sulfate-reducing processes. Among these seven processes, the first four of them are related to the hydrogen production process, and the remaining three are related to the consumption of
Mar 26, 2021 · 2. Agri-Food Waste: A Rising Problem or a Valuable Resource? Among the different food sectors, it is estimated that fruit and vegetables represent a large part of waste production, notably in the detail that about 45% of the total produced amount is lost in the production and consumption chains, generating a great quantity of waste material [9,10].
After hiring a fermentation expert to help reduce food waste, Id Est Hospitality Group saw their food cost drop from 32% to 22%. Kelly Whitaker, founder and chef, hired Mara King, fermentation specialist (both pictured), to pursue a zero waste model in the group’s different restaurants. Whitaker points out he doesn’t like using the term
Feb 25, 2023 · After pretreatment, 300 mL WAS was placed into a series of anaerobic fermentation reactors and cultured in an air bath shaken at 120 rpm at 35 ± 1 °C for 10 days. Before fermentation, oxygen was removed by blowing off nitrogen for 10 min to ensure strict anaerobic conditions. Three replicates were performed in parallels for each group.
Jan 21, 2016 · In the United States, we waste 40 percent of the food we grow. I would hate to waste any of the delicious produce I bring home from the farmer’s market. But occasionally I don’t get to some of it right away and I have to do something with it before it starts to go off. Above left: fermented salsa ( get the recipe)
39.4.2 Fermentation of agri-food waste. Fermentation is a process of converting the organic material into various products using different microbes, such as bacteria and fungi. There are several different products that could be produced through fermentation, for example, fuels, chemicals, pharmaceuticals, etc.
Jun 1, 2021 · In the present study, we investigated the effects of L. buchneri 30139 alone or in combination with L. plantarum MTD1 on the fermentation and aerobic stability of WPC, SNP, and HMC after 30 and 90
Mar 24, 2022 · From the aforementioned studies, it is evident that microbial fermentation is key to reducing the potential anti-nutritional factors of agro-industrial wastes, thereby improving the bioavailability, digestibility and uptake of proteins and carbohydrates.
Oct 23, 2019 · This work aimed to couple lactate production and subsequent chain elongation to decrease chemicals input such as electron donors and hydroxide for pH control in repeated-batch food waste fermentation.
Feb 23, 2022 · Food waste can be used as a substrate for single cell protein production suitable for animal feed. In this study, animal and agricultural food waste, represented by fish, pineapple, banana, apple, and citrus peels, have been used simultaneously as a fermentation substrate for single cell protein production by Saccharomyces cerevisiae, to
Jun 1, 2024 · In comparison, WAS is obtained without any fee, but the alkaline anaerobic fermentation process requires the addition of NaOH at a unit price of 0.072 €/kg (Zhang et al., 2022a). The overall cost of the HAD process with FL was calculated to be 0.062 €/m 3, which was more than 30% lower than that of methanol. Hence, the WAS fermentation
