Write down the scope of microbiology.

The scope of microbiology :

  • Production of Antibiotics
  • In alcohol & vinegar industry
  • Vitamin Production
  • Productions of Acids and enzymes
  • Baking Industry
  • Cosmetics and Perfume
  • Used in the production of dairy products
  • Used as food

Production of Antibiotics

Antibiotics are compounds that can inhibit the growth or kill microorganisms. There are two main types of antibiotics: bacteriostatic, which inhibit the growth of bacteria, and bactericidal, which kill the bacteria. In 1929, Alexander Fleming discovered penicillin from Penicillium notatum, which became the first antibiotic used to treat bacterial infections. The scope of microbiology includes the study of antibiotics and how they work against microorganisms, as well as the discovery and development of new antibiotics to combat antibiotic-resistant bacteria.

 Examples of some bacteria and fungi which produce antibiotics are given below:

Name of BacteriumName of Antibiotic
Streptomyces aureofaciens  Aureomycin (Tetracycline)  
Streptomyces venezuelae  Chloramphenicol  
Streptomyces rimousOxytetracycline
Streptomyces erythraeusErythromycin  
Streptomyces fradiaeNeomycin  
Streptomyces kanamyceteusStreptomycin
Bacillus subtilisBactriacin
Antibiotic secreting Bacteria
Name of fungi  Name of Antibiotic  
Pencillium notatumPenicillin
Penicillion chrysogenum  Penicillin
Claviceps purpureaErgot  
Penicillium griseofuloum  Griseofulvum  
antibiotic secreting fungi

 In alcohol & vinegar industry

Yeast is a microorganism used in the fermentation of carbohydrates to produce alcohol. One glucose molecule is converted into two ethanol molecules and two carbon dioxide molecules. Clostridium acetobutylicum participates in the production of butyl alcohol. Bacterial actions are involved in the production of vinegar (acetic acid). In the first step, carbohydrates undergo fermentation and are converted into ethanol through the action of yeast. In the second step, aerobic bacteria such as Acetobacter aceti and Mycoderma aceti oxidize the alcohol into acetic acid. The scope of microbiology includes the study of various microorganisms, such as yeast and bacteria, that have important applications in the production of alcoholic beverages, biofuels, and other products through fermentation.

Vitamin Production

 There are various types of vitamins obtained from the microorganisms e.g., Riboflavins(B₂) is obtained from Clostridium butylicum

 Cobalamins (B12) obtained from Pseudomonas denitrificans.

Vitamins A,C,D and E are mostly found in algae.

Fungi (yeast) have high content of Vit B₁ Vit B₁2 and Vit C.

Productions of Acids and enzymes

 List of microorganisms helping in production of acids and enzymes are:

Microorganism  Acids  
Penicillium glaucumGallic acid
Aspergillus gallomycesGallic acid
MucorCitric acid
Aspergillus nigerGluconic Acid
acid secretion by microorganisms
Microorganism  Enzymes
Aspergillus oryzaeAmylase
Bacillus subtilisProtease
Saccharomyces cerevisiaeInvertase
Streptococcus pyrogensStreptokinase
enzymes secretion by microorganism

Baking Industry

Yeast is a microorganism used in the production of bread. Kneaded flour is mixed with yeast and allowed to ferment. Yeast converts starch into sugars and sugars into alcohol and carbon dioxide with the help of the enzyme zymase. As carbon dioxide is released during fermentation, the bread becomes porous and lightweight, with a spongy texture. The scope of microbiology includes the study of various microorganisms, such as yeast, that have important applications in the food industry, particularly in the production of fermented foods like bread.

 Cosmetics and Perfume

Certain lichen species, such as Evernia and Ramatina, are used to make perfumes and soaps. Carrageenan, a mucilaginous substance, is secreted from seaweed and used in the production of ice cream, paint, shampoo, and other products. The scope of microbiology includes the study of various organisms, such as lichens and seaweed, that have important applications in the cosmetics, food, and pharmaceutical industries.

 Used in the production of dairy products

 Dairy products such as curd, butter, cheese and ghee are manufactured from bacterial activity. List of microorganisms used in diary industry are:

Lactobacillus lactisCheese
Lactobacillus vulgaricusYoghurt
Streptococcus lactisCurd
Streptococcus lactisButter
Streptococcus lactis & Streptococcus cremorisButter milk
microorganism used in dairy industry

Agriculture & Soil fertility

Nitrogen is essential for the synthesis of proteins, nucleic acids, and other nitrogen-containing compounds. Plants take up nitrogen in the form of nitrates. Nitrogen fixation is done by many organisms, including algae (Anabina, Nostoc), bacteria (Nitrosomonas and Nitrobacter), and root nodules of leguminous plants (Rhizobium leguminosarum). Saprophytic fungi disintegrate decaying organic matter, releasing minerals that can be absorbed by plants. The scope of microbiology includes the study of various organisms, such as algae, bacteria, and fungi, that play essential roles in nitrogen fixation, nutrient cycling, and plant growth.

Used as food

Algae like Gelidium and Gracilaria produce agar-agar, a jelly substance used in the manufacture of ice cream. Some seaweeds, such as Laminaria, contain a lot of iodine, which is an essential mineral for the thyroid gland. Saragassum and Macrocystis are used as food for marine and domestic animals. Reindeer moss (Cladonia rangiferina) in the arctic region is eaten by reindeer and cattle, and Iceland moss (Cetraria islandica) has been used as food by humans in Iceland. The scope of microbiology includes the study of various organisms, including algae and lichens, which have important applications in various fields, such as food production and medicine.

Scope of microbiology is very broad.
