Mar 2, 2024 · Microbial cell factories, renowned for their economic and environmental benefits, have emerged as a key trend in academic and industrial areas, particularly in the fermentation of natural compounds. Among these, plant-derived terpenes stand out as a significant class of bioactive natural products. The large-scale production of such terpenes, exemplified by artemisinic acid—a crucial

Electro-fermentation (EF) has been extensively studied for recovering hydrogen and phosphorus from waste activated sludge (WAS), while was limited for the further application due to the low hydrogen yield and phosphorus recovery efficiency. This study proposed an efficient strategy for hydrogen and

Jul 1, 2024 · Insights into the effect of nitrate photolysis on short-chain fatty acids production from waste activated sludge in anaerobic fermentation system: Performance and mechanisms Author links open overlay panel Zhihong Liu a b , Zhixuan Cui a , Zhengtong Guo a , Dengfei Li a c , Zhangwei He d , Wenzong Liu e , Xiuping Yue a c , Aijuan Zhou a c

Aug 25, 2022 · In order to further optimize the application of fermentation bedding system and evaluate its improvements on low temperature, low humidity and other adverse environments of animal breeding in winter, we tested the waste discharge and performance of 12,921 breeder ducks from November to January.

Bokashi fermentation is the only solution that avoids all of the problems listed above. Bokashi Pet Cycle Fermentation Systems safely and rapidly transform pet waste into a product that restores nutrients and microbes to the soil for ornamental plants, making it the better, simple choice for pet waste disposal.

Aug 15, 2023 · The integrated fermentation–MFC can be realized as a new system to simultaneously produce bioenergy in multiple forms from organic waste. However, the integrated fermentation–MFC system lacks a sustainable process design that considers viability across technical, economic, and environmental sectors.

Bokashi is an anaerobic fermentation process. It needs to be kept as free from oxygen as possible. It’s important, therefore, to compress each day’s waste flat into the container to eliminate any air pockets and to avoid stirring up the previous day’s waste when putting in new garbage.

Jul 9, 2021 · Bioelectrochemical systems (BESs) are a new and emerging technology in the field of fermentation technology. Electrical energy was provided externally to the microbial electrolysis cells (MECs) to generate hydrogen or value-added chemicals, including caustic, formic acid, acetic acid, and peroxide. Also, BES was designed to recover nutrients, metals or remove recalcitrant compounds. The

Fermentation products are considered waste products, since they cannot be metabolized further without the use of oxygen. [citation needed] Fermentation normally occurs in an anaerobic environment. In the presence of O 2, NADH, and pyruvate are used to generate adenosine triphosphate (ATP) in respiration. This is called oxidative phosphorylation

Jan 1, 2018 · Waste composition varies widely across the various sectors of the food supply chain, which makes standardizing a food waste fermentation production process difficult. Food waste can be utilized in ethanol production to a significant extent, but producing other higher alcohols needs extensive research.

There are two mechanisms by which chemoheterotrophs can generate ATP: respiration and fermentation. Although respiration relies on the generation of a proton gradient and ATP synthesis by oxidative phosphorylation, ATP synthesis in fermentation is entirely through substrate-level phosphorylation in metabolic pathways.

Nov 1, 2015 · Fermentation has always been an important part of human history. Human beings are known to have made fermented foods since Neolithic times. With the discovery of microorganisms in the 19th century, fermentation became a viable route to produce synthetic chemicals and antibiotics.

Mar 5, 2022 · Rambabu et al. obtained 103.97 mmol H 2 /L using C. thermocellum to produce biohydrogen from date seeds waste through dark fermentation system operated at 50 °C and initial pH 7. Tian et al. ( 2015 ) also used C. thermocellum to ferment sugarcane bagasse at 55 °C and obtained 4.89 mmol H 2 /g medium added.

Oct 10, 2020 · The first part dealt with the integration of a continuous acidogenic fermentation system using catering industry waste (CIW) as feedstock and a PEMFC for electricity production, with the full characterisation of the process input and output streams (FW, sodium hydroxide (NaOH), organic acids, sludge, H 2 and CO 2).

Oct 1, 2012 · To efficiently convert food waste to biogas, it is necessary to choose the most appropriate process, reactor system and parameters. In this work, to define the most efficient method, fermentation experiments were carried out in two reactor types: a CSTR (Continuous Stirred Tank Reactor) and an FBR (Fluidized Bed Reactor).
