Feb 1, 2016 · Genomatica’s fermentation model has been used as a tool for large-scale bioreactor design, techno-economic assessment, and design of bioreactor scale-down experiments. Genomatica recommends building process modeling tools with flexibility and user-friendliness in mind to ensure the models are leveraged at every stage of the project.
May 16, 2024 · Biogas is a renewable energy source generated through the anaerobic digestion (AD) of organic feedstocks. This study aims to quantify the biogas production potential (BPP) of fruit wastes via semi-continuous lab-scale mesophilic AD over a total of 100 days. The feed was composed of 80% banana peelings and 20% pineapple residues, mimicking the waste composition of a Costa Rican fruit processing
Industrial fermentation is a chemical engineering term used to describe the processes that utilize a chemical change induced by a living organism or enzyme, in particular bacteria, yeasts, molds, or fungi, that produces a specific product [1 ]. Although in the biochemical context the word “fermentation” describes the anaerobic metabolic
Mar 8, 2022 · 4.3.2 Anaerobic Fermentation. Anaerobic fermentation is usually a slower process and occurs when oxygen in the fermentation broth is replaced with nitrogen, carbon dioxide, or any other by-product of the fermentation process (Huang and Tang 2007). In the absence of oxygen, pyruvic acid which is the final product of glycolysis can be directed
Mar 22, 2021 · A. AbiHek. The document discusses large scale fermenter design and controls for industrial fermentation processes. It describes fermenters as closed containers used for culturing microorganisms that require controls for temperature, pH, aeration, and agitation. Typical features of industrial fermenters include a cooling jacket, aeration system
Sep 15, 2023 · AF can achieve efficient organic solid waste treatment and contribute to the development of a low-carbon economy and the replacement of clean energy. The synthesis, preparation, processing and application of AF products have enormous potential for large-scale development, and their market demand is rapidly increasing.
Aug 25, 2021 · This study focusses on the design and scale-up of industrial lactic acid production by fermentation of dairy cheese whey permeate based on standard methodological parameters. The aim was to address the shortcomings of standard scale-up methodologies and provide a framework for fermenter scale-up that enables the accurate estimation of energy consumption by suitable selection of turbine and
Feb 1, 2022 · Large-scale industrial fermentors are almost always constructed of stainless steel. A fermentor is a large cylinder closed at the top and t he bottom and various pipes and valves are fitted int o i t.
The first truly large-scale aseptic anaerobic fermentation vessels were developed in the wake of the process developed (during the First World War, 1914-1918) by Weizmann and co-workers of U.K. to produce acetone by a deep liquid fermentation using Clostridium acetobutylicum. The large-scale aerobic fermentation vessels were first used
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
Aug 3, 2023 · In a pilot-scale fermenter normally the steel contains around 10-13% of chromium. In many cases nickel is also mixed in high concentration with the chromium to make the steel more corrosion resistant and it also provides engineering advantages. In this modern-day, stainless steel fermenters are mostly used for industrial production.
Jan 1, 2024 · Dry fermentation is an industrial-level process also known as solid-state anaerobic fermentation (SSAF), which involves the fermentation of organic substrate to produce biogas under anaerobic conditions without atmospheric oxygen and other controlled factors.
See Fermentation in food processing. Fermentation also occurs within the gastrointestinal tracts of all animals, including humans. Industrial fermentation is a broader term used for the process of applying microbes for the large-scale production of chemicals, biofuels, enzymes, proteins and pharmaceuticals.
Apr 14, 2023 · The scale-up technology of anaerobic fermentation stirring equipment is worthy of attention. Computational fluid dynamics (CFD) simulations were used to study the scale-up of anaerobic fermentation mixing under different solid content conditions. The applicability of different scale-up criteria was analyzed by investigating the relative parameters, such as the blade tip speed and the Reynolds
Apr 10, 2018 · Lager fermenters are generally three to four times shorter in their diameter than the height and use an operation pressure of 1–1.5 bar. European fermentation tanks for lager beer commonly use shorter tanks with a diameter-to-height ratio of <2:1, which causes fermentation to equalize more completely than in horizontal vessels.
