The design of fermentation equipment has evolved in a largely empirical manner. The earliest fermentations requircd only rudimentary standards of hygiene, cither bccause of thc nature the substrate, or because vigour almost universally adopted for aerobic mirobial processes and for some anaerobic processes. Among the new configurations. two ...
1973/1/1/ · ABSTRACT. The influences of environmental (macro) conditions and those on the cell level are treated from the point of view of heat- and mass-transfer in microbial
2022/4/8/ · 1 INTRODUCTION. Aerobic fermentations are known to be prone to excessive foaming due to surface-active substances in the culture broth. Foam is a complex structure of gas entrapped into liquid films at a volume fraction of 0.50–0.97 (Junker, 2007; Walstra, 1989).Surface-active molecules present in the liquid adsorb at the formed
6 Since most industrial fermentation process are aerobic, the construction of a typical aerobic fermentor (Fig. 2) are show below: Figure 2: A Typical Aerobic fermenter Source: (Gueguim et al ., 2005) 7 2. Aeration System: Aeration system is
2023/8/3/ · Stirrer glands and bearings. The most important factor of designing a fermenter is to maintain aseptic conditions inside the vessel. It is highly challenging in the case of pilot-scale fermenters. Therefore stirrer shafts are required. These stirrer shafts play an important role to seal the openings of a bioreactor.
Basic Fermenter Design : External, Agitation & Aeration, Inlets and Outlets. De Becze and Liebmann (1944) used the first large scale (above 20 litre capacity) fermenter for the production of yeast. But it was during the First World War, a British scientist named Chain Weizmann (1914-1918) developed a fermenter for the production of acetone.
The design and mode of operation of a fermenter mainly depends on the production organism, the optimal operating condition required for target product formation, product
bioreactors and fermenters, including cells (like mammalian cell lines, insect cells, and stem cells), microorganisms (like bacteria, yeasts, and fungi), as well as plant cells and algae. Bioreactor and fermenter are two words for basically the same thing. Scientists who cultivate bacteria, yeast, or fungi often use the term fermenter. The
The various parts of the bioreactor work together to meet the parameters like temperature, nutrients, aeration, and pH for the growth and development of the cells, enzymes, and many more. Some essential parts of a bioreactor are discussed below: Fermenter vessel: Most fermented containers are made of glass and stainless steel to reduce pressure

Most of them are designed to maintain high biomass concentrations, which are essential for many fermentation processes. Fermentor design, quality of construction, mode of operation and the level of sophistication largely depend upon the production organism, the optimal operating conditions required for target product formation, product value
aerobic fermentation vessels were first used in Central Europe during 1930s for the production of compressed yeast; these fermenter had large cylindrical tanks in Fermenter design Article History Received: 24/09/2021 Accepted: 28/10/2021 Article ID: RRBB/111 Corresponding Author: E-Mail: Inderjeetbiotechlkc@gmail
Fermenter Design • A bioreactor is a device in which a substrate of low value is utilized by living cells or enzymes to generate a product of higher value. Bioreactors are extensively used for food processing, fermentation, waste treatment, etc. • On the basis of the agent used, bioreactors are grouped into the following two broad classes:
