Microbes in human welfare

  1. 1. Microbe is a microscopic organism, which may be a single cell or multicellular organism. The study of microorganisms is called microbiology.
  2. 2. But Microbes useful in our daily life, Industrial life etc.
  3. 3. 1: A common example is curd from milk. Lactobacillus is that microbe which convert the milk into curd. It is also known as lactic acid bacteria.
  4. 4. IN OUR STOMACH TOO, THE LAB PLAY VERY BENEFICIAL ROLE IN CHEKING DISEASE CAUSING MICROBES.
  5. 5. 1: Used for making Dosa, Idli and chole bhature. It is due to the production of CO2.
  6. 6.   For making Swiss cheese. There is large holes in Swiss cheese due to larger amount of CO2. Roquefort cheese are ripened by growing a specific fungi on them, which gives a particular flavor.
  7. 7. Industrial fermentation
  8. 8. Even in industry, microbes are used to synthesize a number of products valuable to human beings. Production on an industrial scale, require growing microbes in very large vessel called fermentors.
  9. 9. Microbes especially yeast have Same yeast saccharomyces been used from cerevisiae used for makingtime immemorial for the production bread and commonly of beverages like wine, beer, called brewer’s yeast. whisky, brandy or rum
  10. 10. Anti means ‘against’ Bio means ‘life’. Antibiotics are the chemical substance, which are produced by some microbes and can kill or retard the growth of other microbes. Ex like penicillin.
  11. 11. After penicillin, other antibiotics were also purified form other microbes. Antibiotics have greatly improved our capacity to treat deadly disease such as plague, whooping cough(kali khansi) and leprosy(kusht rog). Which used to kill millions all over the globe. Today, we can’t imagine a world without antibiotics.
  12. 12. Microbes are also used for commercial and industrial production of certain chemicals like organic acids, alcohols and enzymes. 1 :- Aspergillus niger(a fungus) produce citric acid 2:-Acetobacter aceti(a bacterium) produces acetic acid. 3:- yeast for the production of ethanol. 4:- lactobacillus for the production of lactic acid.
  13. 13. Microbes are also used for the production of Enzymes. 1:Lipases are used in detergent formulations and are helpful in removing oily stains from the laundry.
  14. 14. Have you ever noticed the bottled fruit juices bought from the market are clearer as compared to those made at home why? Proteases and Pectinases are the reason for above question.
  15. 15. Strepetokinase produced by strepetococcus and modified by genetic engineering is used as a ‘clot buster’ for removing clots from the blood vessels of patients who have undergone myocardial infection leading to heart attack.
  16. 16. Trichoderma polysporum:CyclosporinA, that is used as an immunosuppressive agent in organ-transplant patients.
  17. 17. Monascus purpureus-: Statin is used for blood cholestrol lowering agents. It acts by competitively inhibiting the enzyme responsible for the synthesis of cholestrol.
