Major Classes of Microbial Products  and Processes

Major Classes of Microbial Products  and Processes (Youtube Video URL is given below)


The major commercial products of microorganisms can be classified as -

1. Microbial cells or biomass.
For example,  single cell protein (SCP)
2. Large molecules like enzymes that are synthesized by microorganisms.
For example, protease, alpha-amylase.
3. Primary metabolite products that means compounds essential for cell growth .
For example, Lactic acid, amino acids.
4. Secondary metabolite products that
means compounds not essential for cell  growth.
For example, alkaloids, glycosides.


Types of Commercial Industries 

On the basis of types of microbial products, commercial industries are classified as -

1. Pharmaceutical chemicals
2. Commercially valuable
chemicals
3. Food supplements
4. Alcoholic beverages
5. Vaccines
6. Deterioration of materials by microorganisms.
7.  Analytical microbiology


1. Pharmaceutical chemicals

Most prominent in this category are the antibiotics and steroid drugs. Other useful substances are insulin and interferon are produced by genetically modified bacteria.


2. Commercially valuable chemicals

This category includes solvents, enzymes, various compounds used as starting materials for the industrial production of other substances.


3. Food supplements

The mass production of yeast, bacteria and algae from inexpensive sources containing inorganic nitrogen salts and other readily available and cheap nutrients, provides a good source of proteins and other organic nutrients useful as food supplements for human and animals.
Large-scale microbial production of amino acids is an attractive industrial process being employed in world.


4. Alcoholic beverages

Brewing, wine making and production of alcoholic beverages constitute some of the oldest and largest microbial industries.


5. Vaccines

Some microorganisms are grown in a very large amount to use as vaccines. The whole cells or some part or product of the cell is used for the preparation of
vaccines.


6. Deterioration of materials by microorganisms

All kinds of materials such as leather, textile, wood, metals optical equipments are subjected to deterioration by the contamination and further growth of microorganisms.
The magnitude of potential destruction with resulting financial losses demands that methods for prevention of destruction be developed.

Industry is responsible to this need and produces many chemicals and treatment processes for this purpose.


7.  Analytical microbiology

Microbiological techniques have been developed for -

a) assaying a variety of products like antibiotics, amino acids,  vitamins.
b) evaluation of wood and paint preservatives.
c) testing the efficacy of sterilization procedures.
