What is the basic design of fermenter?
The vessel should be well equipped to maintain aseptic conditions inside it for a number of days. Aeration and agitation are important for the production of biological metabolites. However, controlled agitation is required to prevent any damage to the cells.
What is the basic design of fermenter and its parts?
A fermentor should provide the facility to control and monitor various parameters for a successful fermentation process. Impellers are an agitation device. They are mounted on the shaft and introduced in the fermentor through its lid. They are made up of impeller blades and the position may vary according to its need.
How will you design and construct a fermenter?
The fermenter consisted of a large cylindrical tank with air introduced at the base via network of perforated pipes. In later modifications, mechanical impellers were used to increase the rate of mixing and to break up and disperse the air bubbles (Fig. 20.1). This process led to the compressed air requirements.
What is the working principle of fermenter?
The air enters the fermentor as a series of tiny bubbles from which the oxygen passes by diffusion into the liquid culture medium. The impeller (also called agitator) is an agitating device necessary for stirring of the fermenter. (ii) It mixes the microbial cells through the liquid culture medium.
What is fermentor and its types?
A fermentor usually refers to the containment system for the cultivation of prokaryotic cells, while a bioreactor grows the eukaryotic cells (mammalian, insect cells, etc). Types of Bioreactor. Continuous Stirred Tank Bioreactor. Airlift Bioreactor. Fluidized Bed Bioreactor.
What are the different types of fermenter?
TYPES OF FERMENTER: Following are the types of fermenter • Airlift Fermenter: • Continuous Stirred Tank Bioreactors: • Photo-Bioreactors: • Bubble Column Fermenter: • Fluidized Bed Bioreactors: • Packed Bed Bioreactors: 14.
What is the function of fermenters?
Fermenters are containers used to grow bacteria and fungi in large amounts, eg Penicillium mould for producing penicillin (an antibiotic). Fermenters are usually made from a metal that will not corrode, such as stainless steel. Some have the capacity to hold thousands of litres.
What is difference between bioreactor and fermentor?
Bioreactor refers to an apparatus in which a biological reaction or process is carried out, especially on an industrial scale whereas fermentor refers to the container in which fermentation takes place.
What are different types of fermenters?
❖ Types of Fermentor: There are six types of bioreactors used in bioprocess technology. The six types are: Page 8 [MICROBIOLO (1) Continuous Stirred Tank (2) Bubble Column Bioreactors (3) Airlift Bioreactors (4) Fluidized Bed Bioreactors (5) Packed Bed Bioreactors (6) Photo-Bioreactors.
Which type of bioreactor is more efficient?
In general, the airlift bioreactors are more efficient than bubble columns, particularly for more denser suspensions of microorganisms. This is mainly because in these bioreactors, the mixing of the contents is better compared to bubble columns.
What are the design considerations for a fermenter?
The design also takes into consideration the capital investment and running cost. • Large volume and low value products like alcoholic beverages need simple fermenter and do not need aseptic condition. • High value and low volume products require more elaborate system of operation and aseptic condition.
What are the objectives of a pilot fermentor?
A fermentor was developed in India at Hindustan Antibiotic Ltd., Pune and named it as “Pilot fermentor”. The objectives include the production of metabolites, enzymes, microbial biomass and recombinant product. A fermentor should be made of a good quality material that can withstand all the conditions inside the vessel.
What is the definition of a fermentor in biology?
Definition, History, Properties, Design and Types – Biology Reader A Fermentor is a device used to accomplish the fermentation process by using microorganisms, and for this reason, it is also called “ Biofermentor or Bioreactor “.
Who was the scientist who invented the fermentor?
In this year, aeration system, water and steam inlet flow was introduced in a fermentor by the scientists Strauch and Schmidt. A fermentor was developed for the yeast production by the scientists De Beeze and Liebmann for the large scale production.
