Feb 15, 2016 · In order to control VOCs, investigation of odor-causing matters of pig manures in aerobic fermentation was carried out in August, 2014 at the Key Laboratory of Energy Resource Utilization From
Sep 16, 2023 · Aerobic fermentation is essential for various industries. It transforms organic molecules into energy-rich compounds in the presence of oxygen. It yields valuable products, like ethanol and renewable energy sources. Unlike anaerobic fermentation, it needs oxygen. Anaerobic fermentation occurs without oxygen and yields lactic acid.
Sep 1, 2016 · The internal and surface odor concentrations reached 664.8 and 132.5 within the first 0–1 days, respectively, because of the metabolism of the psychrophilic and mesophilic aerobic microbes. The internal odor concentration was approximately five times higher than the surface odor concentration, as shown in Figure 3. After the easily degradable
Nov 4, 2022 · Odor ΨΩγemission has become mathvariant="normal" mathvariant="sans-serif-bold-italic" an important issue in kitchen waste management. Ammonia and hydrogen sulfide are the two most important odor sources as they contribute malodor and can cause health problems. As biotreatment and chemical treatment are two majorly applied technologies for odor control, in this study, they were used to
22.4.2 Tempeh. Tempeh is a traditional fermented Indonesian soy food, and prepared from soaked and cooked soybeans by salt-free aerobic fermentation using the mold Rhizopus. During the fermentation, dense cottony mycelium produced binds the soybeans together to form a compact cake.
Jun 6, 2024 · The highest fermentation rate of free LT yeast was similar to that reported by Lúquez-Caravaca et al. 2023 and Puig-Pujol et al. 2013 , where fermentation kinetics with free cells were faster than those with immobilized cells. As noted in these studies, this could be due to the slight stress on the immobilized cells and/or the effect of the
Mar 8, 2022 · 4.3.1 Aerobic Fermentation. Aerobic fermentation occurs at the beginning of the fermentation process and in the presence of oxygen. This is also referred to as “aerobic glycolysis” in living cells, wherein a glucose molecule is converted into two molecules of pyruvic acid through a sequential enzyme-catalyzed biochemical reaction consisting of ten steps.
Organisms carrying out fermentation, called fermenters, produce a maximum of two ATP molecules per glucose during glycolysis. Table 8.2 compares the final electron acceptors and of ATP synthesis in aerobic respiration, anaerobic respiration, and fermentation.
May 7, 2018 · 5 min read. The main difference between aerobic and anaerobic fermentation is that aerobic fermentation regenerates NAD + at electron transport chain whereas the regeneration of NAD+ in anaerobic respiration follows glycolysis. Fermentation is a term used to describe the mechanisms of cellular respiration, which occurs in the absence of oxygen.
May 23, 2024 · 1. Fermenter Vessel. A fermenter is a large cylinder closed at the top and bottom connected with various pipes and valves. The vessel is designed in such a way that it allows to work under controlled conditions. Glass and stainless steels are two types of fermenter vessels used. The glass vessel is usually used in small-scale industries.

The main advantages of passive composting are less capital cost compared with forced aeration, less running cost compared with natural aeration and it is odor free because the composting pile can be covered with finished compost to protect the environment.
The aerobic fermentation reactor was outfitted with a custom-designed thermostat for peritoneal fluid with four cuboid iron boxes inside measuring 15 cm long × 8 cm wide × 15 cm high (Fig. 1). In order to create a good aerobic state and facilitate airflow, an aeration head (1.8 L h-1) was installed at the bottom of the reactor so that oxygen
Apr 4, 2021 · Aerobic composting is a reliable technology for treating human and animal feces, and converting them into resources. Odor emissions in compost (mainly NH 3 and VSCs) not only cause serious environmental problems, but also cause element loss and reduce compost quality. This review introduces recent progresses on odor mitigation in feces composting.
Mar 8, 2022 · A fermenter (bioreactor) is a closed vessel with sufficient aeration, agitation, temperature, and pH regulation arrangements and a drain or overflow vent to extract the waste biomass along with its products from cultured microorganisms. The fermenter is intended for the production of biological products. The fermenter’s design and mode of
