    Economic importance of bacteria

    • The economic importance of bacteria derives from the fact that bacteria are exploited by humans in a number of beneficial ways. Despite the fact that some bacteria play harmful roles, such as causing disease and spoiling food, many bacteria serve important roles in both agriculture and industry. Bacteria is of a vital importance to humans.

      Biotechnology is defined as the use of microorganisms such as bacteria, fungi and algae for the manufacturing and services industries. These include:

      Genetic engineering is the manipulation of genes. It is also called recombinant DNA technology. In genetic engineering, pieces of DNA (genes) are introduced into a host by means of a carrier (vector) system. The foreign DNA becomes a permanent feature of the host, being replicated and passed on to daughter cells along with the rest of its DNA. Bacterial cells are transformed and used in production of commercially important products. The examples are production of human insulin (used against diabetes), human growth hormone (somatotrophin used to treat pituitary dwarfism), and infections which can be used to help fight viral diseases.

      Using biotechnology techniques,or bio medical technology bacteria can also be bioengineered for the production of therapeutic proteins.

      Agriculture bacteria decompoes dead plant and dead bodies in the soil.after decomposition may be just plant regenerate from soil . Agriculture bacteria is useful for our society.because they help in production of food. Bacteria play many useful roles in agriculture from biodegradation to food production. Bacteria are often employed in the dairy industry for ripening cheese and giving certain dairy products a specific aroma. Additionally, bacteria such as Lacto bacilli are known for playing important roles in the process of making butter and ripening milk. Other bacteria including Bacillus aceti are responsible for the conversion of a sugar solution into vinegar.

      Bacterial populations, especially that of are used to separate fibres of jute, hemp, flax, etc., the plants are immersed in water and when they swell, inoculated with bacteria which hydrolyze pectic substance of the cell walls and separate the fibres.These separated fibres are used to make ropes and sacks etc.

      • Fermentation processes, such as brewing, baking, cheese and butter manufacturing, Bacteria, often '''Lactobacillus Bulgaricus'' in combination with yeasts and fungi, have been used for thousands of years in the preparation of fermented foods such as cheese, pickles, vinegar, wine, and yogurt.
      • Chemical manufacturing such as ethanol, acetone, organic acid, enzymes, perfumes etc. In the chemical industry, bacteria are most important in the production pharmaceuticals.
