 In Industrial microbiology is a branch of science that deals with the study and uses of micro-organism which has industrial and economic applications. Industrial Microbiology, microbes classified, characterized are isolated from their natural environment. Further, these micro-organisms are produced on a large-scale by use of a fermentor.

The most important applications of industrial microbiology are using microbes to convert inexpensive raw materials into economically important products. Further, these products go through detection, analysis, assay, purification and recovery to make them safe and effective. The end products are valuable, but the microbes creating these products are equally important.

During the process of industrial fermentation, microbial cells produce extra-cellular as well as intracellular enzymes. These enzymes play an important role in fermentation, degradation and utilization of media components. Enzymes can be used as a product by itself and have many end-use applications. For example, enzymes like amylase and proteases are used in a variety of products.

Nuclear Staining by Giemsa’s Method and its Details

Nuclear Staining by Giemsa’s Method and its Details Aim To stain bacteria nuclear material by Giemsa’s staining technique. Approach DNA is a principle genetic material of all micro-organisms except some viruses. Bacterial cell lacks a well-organised nucleus. It is the very essential structure of a living cell. Nucleus performs important functions like growth, metabolic activities, … Read more Nuclear Staining by Giemsa’s Method and its Details

Taxonomic Differentiation of Microbes

Definition of Microbiology

It is a branch of science that deals with the study of microscopic forms of life these micro-organisms are less than 1 mm in size.

Characteristics of Micro-organisms 

  • These micro-organisms are very small in size generally less than 1 mm.
  • They are not visible through our naked eyes.
  • These organisms are either unicellular or multicellular.
  • Prokaryotic or eukaryotic in nature.
  • They may be motile or non motile.
  • Micro-organisms are present everywhere in our surrounding like air, water,soil, dust and bodies of plants, animals and human beings.

1. Protozoa

Amoeba
Amoeba
  •  Protozoa are unicellular, eukaryotic in nature.
  •  They are parasitic or saprophytic.
  •  The size range of protozoa is generally 10 – 50 micrometer.
  •  These organisms generally exist in aqueous environment and soil.
  •  They show motility by flagella, cilia, or pseudopodia.
  • Protozoa can absorbs their food material by cell membrane or by engulfing the food by phagocytosis.
  • Some parasites are pathogenic in nature .They can reproduce sexually or asexually.
