4 天之前 · Summary. Anaerobic conditions are maintained in some ecosystems where the rate of oxygen supply is lower than that of consumption. Organic compounds are removed from anaerobic ecosystems through the concerted action of fermentative and anaerobic respiratory microorganisms. In microbiology, the term ‘fermentation’ can be used to
2018/5/29/ · The curves representing CO 2 released during the anaerobic fermentation in all three fermentations were of similar shape, although more CO 2 was released in both fermenters containing plasma pre
2024/1/2/ · Table 4 shows the energy yield values of the self-fermented anaerobic CSTR using the heating values of 120 kJ/g VS fermenter for hydrogen gas . The energy yields from the hydrogen fermenter was 64,300 kJ/g VS fermenter and only 300 kJ/g VS fermenter for the TP and the control phase, respectively, and this confirms that the
2024/1/29/ · The objective of this paper is to gain insights into the synergistic advantage of anaerobic co-fermentation of heat-treated sludge (HS) with food waste (FW) and heat-treated food waste (HFW) for hydrogen production. The results showed that, compared with raw sludge (RS) mixed with FW (RS-FW), the co-substrate of HS mixed with either FW
2024/3/11/ · Abstract Ionizing irradiation, as a new pretreatment method for the anaerobic fermentation of organic pollutants, is featured with fast reaction speed, good treatment effect, no need to add any chemical reagents, and no secondary pollution. This study explores the mechanism of improving anaerobic fermentation performance of rice
2022/4/22/ · The experimental conditions are R1 was an anaerobic fermenter (AF) operated as control, R2 consisted of an AF with electrodes operated in open circuit, R3 was an AF with electrodes operated in a closed circuit with 100 Ω as load and R4 was an electro-fermentation reactor with an applied cathodic potential of −0.8 V vs. Ag/AgCl.
2021/12/1/ · One of the most essential strategies to reduce process instability and enhance fermentation efficiency is the co-fermentation of two or more substrates. Waste activated sludge (WAS) is another large generated MSW derived from wastewater treatment plants, which has been estimated to be 70 million tons (80% moisture) by 2025 in China (
2017/7/17/ · Background The fact that microalgae perform very efficiently photosynthetic conversion of sunlight into chemical energy has moved them into the focus of regenerative fuel research. Especially, biogas generation via anaerobic digestion is economically attractive due to the comparably simple apparative process technology and the
2020/2/10/ · Even though fermentation happens without oxygen, it isn't the same as anaerobic respiration. Anaerobic respiration begins the same way as aerobic respiration and fermentation. The first step is still glycolysis, and it still creates 2 ATP from one carbohydrate molecule. However, instead of ending with glycolysis, as fermentation
Energy biotechnology / Environmental biotechnology. Syed Shams Yazdani, Ramon Gonzalez, in Current Opinion in Biotechnology, 2007. Conclusions. The use of anaerobic fermentation to convert abundant and low-priced glycerol streams generated in the production of biodiesel into higher value products represents a promising route to achieve
5 天之前 · Unlike anaerobic fermentation which occurs in the absence of oxygen, aerobic fermentation is a more efficient way to generate energy, producing more ATP molecules. It is the primary method of energy production in most aerobic organisms, including humans. Aerobic fermentation is important because it provides the energy needed for cells to …
2024/1/30/ · Anaerobic respiration is less energy-efficient but allows survival in habitats that lack oxygen. Within the human body, both aerobic and anaerobic respiration are important to muscle function. Muscle cells specialized for aerobic respiration provide endurance and those specialized for lactic acid fermentation support short but intense …
Several other studies employing energy-efficient extraction of VFA, such as solar-assisted membrane distillation (MD), pressure-driven operations In summary, VFA makes a versatile end-product of anaerobic fermentation with high value, demand, and applicability. In a circular economy setting, the goal is to reuse waste and valorize it to ...
2024/3/1/ · 1. Introduction. Nowadays, the escalating depletion of non-renewable resources, including coal and oil, is driving the pursuit of renewable energy and chemical production [1].Anaerobic fermentation is a widely used biotechnology to achieve resource recovery from biowastes by generating renewable biochemical or bioenergy [2].Methane …
