Apr 1, 2020 · Conversely, the gap in the energy recovery between the single-phase AcoD systems and two-phase AcoD systems in which the aciodgenic digesters were operated at the ethanol-type fermentation pH (4.07) further increased (Fig. 6 B), suggesting that the DIET-based syntrophic metabolism established led to a high-efficiency energy recovery.
Enhancing denitrification efficiency for nitrogen removal using waste sludge alkaline fermentation liquid as external carbon source Environ Sci Pollut Res Int . 2019 Feb;26(5):4633-4644. doi: 10.1007/s11356-018-3944-4.
Nov 1, 2022 · High treatment capacity for food waste (FW) is required due to the huge amount generated worldwide. Conversion of FW to volatile fatty acids (VFAs) via anaerobic fermentation is a promising technology; however, inhibition of VFAs production could easily occur at high loadings.
Biorefinery Concepts: Integration of multiple fermentation processes within a single facility to maximize resource efficiency and product diversity. Circular Economy Initiatives: Closed-loop systems and biorefinery concepts aim to minimize waste and maximize the utilization of raw materials and by-products. Comparison of Common Fermentation
5 days ago · This study explores the upcycling of cotton residues from textile industry as a feedstock in a biorefinery model. The proposed process is to enzymatically digest the crude biomass to produce bioethanol, transforming the non-hydrolyzed residue into both carboxymethylcellulose (CMC) and cellulose acetate (CA). Enzymatic hydrolysis experiments of the raw cotton (without any chemical pretreatment
Nov 1, 2023 · In this study, a robust and high-efficient nitrogen removal efficiency (95.0–93.1 ∼ 86.8–93.4%) with desirable effluent quality (3.0–4.1 ∼ 7.9–4.9 mg/L) under long-term decreased temperatures (30 °C→25 °C→20 °C) was achieved in a zero-external carbon Partial Nitritation/Anammox combined with in-situ sludge Fermentation
Aug 9, 2019 · 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 interest using solid biomass (wastes and by
Apr 10, 2018 · Fed-batch, continuous, and batch fermentation systems can be selected for high efficiency. Continuous and fed-batch systems can handle substrate restriction amid fermentation procedures. Higher efficiency also can be achieved by the immobilization of cells, which can be derived incrementally from the biomass collection in the bioreactor
The abundance of organic solid waste throughout the world has become a common issue that needs complete management at every level. Also, the scarcity of fuel and the competition between food and substance as an alternative to a petroleum-based product has become a major problem that needs to be properly handled. An urge to find renewable substances for sustainable development results in a
biological fermentation limit has been developed by a team of scientists led by Prof. Bruce Logan at Pennsylvania State University. In the absence of O 2, and by adding a slight amount of negative potential (–250 mV) to the circuit, Logan’s group has produced hydrogen from acetate (a fermentation byproduct) at a molar yield of 2.9–3.8 (versus
3 days ago · Using the two-stage methane fermentation of slaughterhouse waste from poultry processing, Wang et al. achieved a methane production efficiency of 230 dm 3 /kg COD . The reason for the lower efficiency of biogas production in this research could be a lower fat content and a higher content of raw ash and carbohydrates.
Nov 10, 2021 · 3.1 Free-cell batch fermentation of algal hydrolysate fermentation in bioreactor. The algal hydrolysate used for this experiment contained about 8 g/L glucose and 8 g/L mannose as the primary sugars (Figure 2). During the fermentation, yeast cells used glucose earlier than mannose.
Apr 1, 2024 · In this study, the high efficiency LA production technology was acquired from anaerobic co-fermentation of SM and AW through enzymatic pretreatment. This technology has a wide application prospect. Firstly, the abundance and low cost of SM and AW as substrates, making them an attractive option for LA production.
Oct 1, 2022 · These properties all contributed to the high-efficiency EGSB-AcoD treating FW and mature leachate. However, there are still some attentions to be paid when using EGSB to treat FW. As a high-solid waste, the accumulation of FW residue inside the reactor needs to be taken into account (Gao et al., 2020). The concentrations of MLSS and MLVSS were
1 day ago · This study primarily explored the adsorption efficiency and mechanism of biochar, derived through high-temperature pyrolysis of OPW/WAS co-fermentation residue, on NH 4 +-N. The highest NH 4 + -N removal rates were 9.76, 44.1, 76.0, and 97.8% at biochar dosages of 3, 5, 8, and 10 g/L, respectively.
