Fermentation | Free Full-Text | Advanced Fermentation

Aug 1, 2023 · Agricultural waste is rich in nutrients needed for microbial growth. Fermentative production of lactic acid from non-food-competing agricultural waste could reduce the cost of lactic acid production while addressing environmental concerns. This work provided an overview of lactic acid fermentation from different agricultural wastes.

Innovative Production of Bioproducts From Organic Waste

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

Fermentation | Definition, Process, & Facts | Britannica

Mar 28, 2024 · fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old. The frothing results from the evolution of carbon dioxide gas, though this was not recognized until the 17th century.

17.1D: Large-Scale Fermentations - Biology LibreTexts

Dec 24, 2022 · Key Points. Large-scale fermentations are utilized to create massive quantities of ethanol which are used for food production, alcohol production, and even gasoline production. Fermentation is characterized by the metabolic processes that are used to transfer electrons released from nutrients to molecules obtained from the breakdown of those

Butanol production from food waste: a novel process for

Sep 15, 2015 · 103 Citations. Metrics. Abstract. Background. Waste is currently a major problem in the world, both in the developing and the developed countries. Efficient utilization of food waste for fuel and chemical production can positively influence both the energy and environmental sustainability.

Fermenter - an overview | ScienceDirect Topics

Finally, fermenters are geometrically designed as packed-bed fermenters, bubble-column type, air-lift fermenter, and tank fermenters (Figs. 5–8).The fed-batch, chemostat, and membrane cell recycle systems were specially studied to overcome growth inhibition of low organic substrates concentrations (Chen, 1996; Hochfeld, 2006; Liu, Sun, & Chen, 2014).

Fermenter explained - Renergon

Fermenter For Biogas Production Explained. What is a fermenter? Methane fermentation and anaerobic digestion are used to produce biogas from organic waste and leftovers. They are both operated under an anaerobic condition, but the chemical paths used differ. Dry fermentation is used for the treatment of the organic fraction of municipal solid

Fermentation - Wikipedia

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

Enzyme-enhanced acidogenic fermentation of waste activated

Feb 1, 2024 · Anaerobic fermentation is widely installed to recovery valuable resources and energy as CH 4 from waste activated sludge (WAS), and its implementation in developing countries is largely restricted by the slow hydrolysis, poor efficiency, and complicate inert components therein. In this study, enzyme-enhanced fermentation was conducted to

Fermenters for Biological Phosphorus Removal Carbon Augmentation

VFAs. Imported organics (food waste, fats, oils, and grease, etc.) could also be used as feedstock for a fermenter, but operator attention is required in the handling of the additional load to the fermentation system. In one instance, molasses was used to increase a fermenter VFA yield (Thomas et al. 2003).

Fermenter Design | SpringerLink

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

Recent Trends in Biogenic Gas, Waste and Wastewater Fermentation

Jul 23, 2022 · In this domain of progressive research, lab-, pilot-, and demonstration-scale studies are dealing with the fermentation of biogenic gases (e.g., CO 2, CO, and CH 4 ), waste or wastewater to produce a range of biofuels and valuable products, based on the activity of pure or mixed cultures of native or recombinant aerobic and anaerobic bacteria

Anaerobic fermentation of organic solid waste: Recent updates

Sep 15, 2023 · Abstract. The effective conversion and recycling of organic solid waste contribute to the resolution of widespread issues such as global environmental pollution, energy scarcity and resource depletion. The anaerobic fermentation technology provides for the effective treatment of organic solid waste and the generation of various products.

Fermentation of Agri-Food Waste: A Promising Route for the
