Beer Fermentation and its Details

Beer Fermentation and its Details Introduction Fermentation of beer is a very complex process. The products formed after fermentation are fermented product, alcohol, glycerol and acid. There are some different types of beer like Ale beer, Porter beer, Bock beer, Lager beer, Pilsner beer. Composition of typical American beer  Bland flavour pH – 4.3 Alcohol … Read moreBeer Fermentation and its Details

Sterilization of Fermentation Media

Sterilization of Fermentation Media Sterilization of fermentation media play a important role in fermentation .If the fermentation media is not sterilized properly or we can say if the media gets contaminated it can lead to economic loss.The contamination of media can effect the yield of product,it can change the product or it can effect the … Read moreSterilization of Fermentation Media

Fermentation Media

Design of Fermentation Media

In a fermentation process, the choice of the most optimum micro-organisms and fermentation media is very important for high yield of product. The quality of fermentation media is important as it provides nutrients and energy for growth of micro-organisms. This medium provides substrate for product synthesis in a fermentor.

Fermentation media consists of major and minor components.

  • Major components include Carbon and Nitrogen source.
  • Minor components include inorganic salts, vitamins, growth factors, anti-foaming agents, buffers, dissolved oxygen, other dissolved gases, growth inhibitors and enzymes.

Nutrients required for fermentation media also depend upon the type of fermentation organisms as well as the type of fermentation process to be used. Poor choice of fermentation media might result in poor yield of output. Types of nutrients present in the fermentation media always determine the yield of the product.

There are two uses of fermentation media

  1. Growth media
  2. Fermentation media

Growth medium contains low amounts of nutrients.It is useful in creating raw material for further fermentation processes.

Fermentation media contains high amounts of nutrients. It is used in creating final products using fermentation.

For example, growth of yeast requires 1% carbon. But during fermentation of alcohol, yeast requires 12 to 13 % carbon in the medium.

Fermentation

Fermentation can be defined as a metabolic process in which cheap raw materials such as sugar or carbohydrates are converted into economically important products like acids, gases and alcohols by micro-organism. This process is carried out in a equipment called as fermentor.

What is a Fermentor?

A Fermentor can be defined as a vessel in which sterile nutrient media and pure culture of micro-organism are mixed and fermentation process is carried out under aseptic and optimum condition.

Fermentor provides a sterile environment and optimum condition that are important for growth of micro-organisms and synthesis of desired product.
