What is submerged liquid fermentation?

Submerged fermentation is a method of manufacturing biomolecules in which enzymes and other reactive compounds are submerged in a liquid such as alcohol, oil or a nutrient broth. The process is used for a variety of purposes, mostly in industrial manufacturing.

What is submerged culture fermentation?

Submerged fermentation involves inoculation of the microbial culture into the liquid medium for production of the desired product. Most of the commercial products are produced through the SmF processes (Subramaniyam and Vimala, 2012). Fermentation processes are broadly classified into aerobic and anaerobic processes.

What is submerged fermentation used for?

Submerged fermentation is a process involving the development of microorganisms in a liquid broth. This liquid broth contains nutrients and it results in the production of industrial enzymes, antibiotics or other products.

What is the enzyme used in the fermentation process?

Few of the common types of enzymes include the following. Proteases: Breaks down protein. Lipases: Breaks down lipids into glycerol and fatty acids. Amylases: Breaks down starch in simple sugars.

Which of the following is not true for submerged liquid fermentation?

5. Which of the following is not true for submerged liquid fermentation? Explanation: Usually in submerged liquid fermentation, the bioreactor used are of larger size because the concentration of media is less and is diluted. The small-sized bioreactors can be used in the solid-state fermentation.

What is the difference between solid state fermentation and submerged fermentation?

The key difference between solid state fermentation and submerged fermentation is that solid-state fermentation involves the cultivation of microorganisms on a solid substrate with a low moisture content while submerged fermentation involves the cultivation of microorganisms in a liquid medium which has more than 95% …

What is the difference between solid-state fermentation and submerged fermentation?

Which of the following is the example of submerged fermenter?

2.1 Citric Acid Production An example of submerged fermentation can be seen in the production of citric acid. Every year over a million tones of citric acid is produced by fermentation.

Which enzyme is used in alcoholic fermentation?

enzyme complex involved in alcoholic fermentation is zymase.

Why is submerged fermentation better than solid state fermentation?

There are a number of advantages of the use of solid state fermentation over submerged fermentation. It is a much more simple process which requires a lot less energy. It produces a much higher volumetric productivity and it is similar to the natural environment of certain fungi.

Why is solid-state fermentation better than submerged fermentation?

Although less employed at an industrial level, SSF is recognized to commonly offer a series of advantages over submerged (or liquid) fermentation (SmF), such as higher yields and productivities, extended stability of products, lower production cost, lower protein breakdown (which is especially important if an enzyme is …

How are enzymes used in a submerged fermentation?

Submerged fermentation is a method of manufacturing biomolecules in which enzymes and other reactive compounds are submerged in a liquid such as alcohol, oil or a nutrient broth The process is used for a variety of purposes, mostly in industrial manufacturing

How does submerged fermentation lead to industrial level production?

The development of techniques such as Solid State Fermentation (SSF) and Submerged Fermentation (SmF) has lead to industrial-level production of bioactive compounds. Submerged fermentation is a method of manufacturing biomolecules in which enzymes and other reactive compounds are submerged in a liquid such as alcohol, oil or a nutrient broth.

What’s the difference between solid state and submerged fermentation?

Submerged fermentations (SmF) and solid-state fermentations (SSF) are the two methods widely employed for the production of amylases. The solid-state fermentation is a new method, whereas SmF is a traditional method for enzyme production from microorganisms which has been used for a longer period of time.

Why is submerged culture used for the production of enzymes?

Submerged culture fermentation has been widely used for production of enzyme because in submerged fermentation unwanted metabolites are not produced and purification of enzymes takes place in easy way. Aspergillus niger or Bacillus culture.
