Apr 1, 2024 · To restore the anaerobic environment, the bioreactors were flushed with pure N 2 before sealing, except the reactors for Batch#3, which were flushed with pure H 2.At regular time intervals (t = 0 h; 24 h; 48 h; 72 h; 144 h; 192 h), the reactors were sampled to perform the chemical characterization of the fermentation broth.
Jun 5, 2021 · Organic acids, e.g, citric acid, fumaric acid, lactic acid, malic acid, pyruvic acid and succinic acid, have important role in the food industry and are potential raw materials for the sustainable chemical industry. Their fermentative production based on renewable raw materials requires innovatively designed downstream processing to maintain low environmental impact and resource efficiency
Feb 1, 2023 · Notably, the total contents of carboxylates and alcohols are dose-dependent during the initial 4 days of fermentation, and the impact of Fe (VI) on lag phase of MCFAs production occurs in a similar way, such as lower carboxylates and alcohols contents, and increased lag phase in the 85 mg Fe/g TSS group.
Feb 1, 2022 · 1. Introduction. Transforming organic-rich waste into bio-based resources is a critical step towards a sustainable society. Anaerobic digestion is a proven technology that is widely used to convert organic wastes into valuable resources, usually biogas.
Jan 1, 2018 · The commercial production of ethanol involves several steps: feedstock preparation, pretreatment, inoculum development, fermentation, and downstream processing. The following sections describe the unit processes involved in ethanol production, with a general process flow diagram presented in Fig. 5.4.

Food waste-based bio-fertilizers production by bio-based fermenters and their potential impact on the environment. Mamun Mandal a. , Anamika Roy a. , Sujit Das a. ,
Apr 20, 2020 · The experiment was composed of two parts. One was the fermentation liquid production through food waste fermentation. The other one was the denitrification of simulated secondary wastewater using the produced fermentation liquid as carbon source.
Jun 1, 2022 · A model FW was prepared according to Capson-Tojo et al. (2017) to ensure the relative stability and reproducibility of the substrate properties during the experiments. This substrate, composed of fruits and vegetables (25.9% apple and 25.9% lettuce), carbohydrates (25.9% potato, 4.8% wheat meal and 6.2% bread), meat (4.1% chicken and 4.1% beef), dairy products (1.9% yoghurt) and pastries (1.5%
Jun 1, 2019 · Conclusions. This study assessed how the fermentation process of a specific waste mixture of urban origin could be optimized in terms of organic matter solubilisation and VFA production. For this work, a mixture composed by thickened WAS (65–70% v/v) and squeezed OFMSW (30–35% v/v) was used as renewable feedstock.
Oct 1, 2012 · 2.2. Experimental setup. In both reactor types, the experiments were conducted continuously with increasing organic loading rates. Compared to fermentation with the CSTR, the organic loading rate of the FBR system was increased in larger steps over shorter periods based on the known characteristics of the reactor system as well as time constraints.
Oct 1, 2023 · 2.2. Microorganism growth and culture conditions. R. palustris (No. CICC 23812) was purchased from the Center of Industrial Culture Collection, China. The bacterium was cultivated on tryptic soy agar (TSA) medium (tryptone 15 g⋅L −1, soybean peptone 5 g⋅L −1, NaCl 5 g⋅L −1) at 32 °C, and the luminous intensity was maintained at 3000 lx using a tungsten lamp.
May 24, 2021 · Associated Data. Data Availability Statement. Go to: Abstract. Food waste biorefineries for the production of biofuels, platform chemicals and other bio-based materials can significantly reduce a huge environmental burden and provide sustainable resources for the production of chemicals and materials.
Patrick Biggs, Ph.D. Nutritionist, Companion Animal Technical Solutions. Print. Each chicken produces many pounds of manure per month. Sound like a problem? Definitely not! Chicken waste is not waste at all; it’s actually garden gold that can be used as an organic fertilizer for your lawn and garden.
Nov 1, 2023 · In addition to VFA, agricultural wastes can be converted into lactic acid (LA) in the anaerobic fermentation process. It has been reported that high-strength LA fermentation broth (LA concentration of 25.80 g/L) can be produced from anaerobic co-digestion of swine manure and apple waste (Cao et al., 2021, Lian et al., 2020).
Sep 1, 2023 · Section snippets Kitchen wastewater, excess sludge, and inoculum. The composition of actual kitchen wastewater collected from the canteen of Beijing Forestry University varied depending on the sampling event, leading to inconsistent feeding conditions across different batches of fermentation tests.
