Microbes in human welfare

  1. 1. MICROBES IN HUMAN WELFARE
  2. 2. <ul><li>MICROBES ARE PRESENT EVERYWHERE. </li></ul><ul><li>IN SOIL, AIR , WATER ETC </li></ul><ul><li>ALSO IN EXTREME CONDITIONS, EXTREMOPHILES </li></ul><ul><li>MICROBES ARE GROWN IN MEDIA TO FORM COLONIES, SEEN WITH NAKED EYE. </li></ul><ul><li>EXAMPLES ARE NUTRIENT AGAR, SABRAUD’S DEXTROSE AGAR ETC. </li></ul><ul><li>MICROBES CAUSE DISEASES IN HUMANS , ANIMALS, PLANTS ETC. </li></ul><ul><li>ALL MICROBES ARE NOT HARMFUL </li></ul>Introduction
  3. 3. MICROBES IN HOUSE HOLD PRODUCTS <ul><li>CURDLING OF MILK </li></ul><ul><li>Lactic acid bacteria is used </li></ul><ul><li>Produce acid by fermentation, which convert or coagulate the milk protein casein to paracaseinate. </li></ul>
  4. 4. <ul><li>Fermentation of dough. </li></ul><ul><li>Puffed appearance is due to CO2. </li></ul><ul><li>Alcoholic fermentation takes place. </li></ul><ul><li>Glucose  Pyruvate </li></ul><ul><li>Pyruvate  Ethanol + CO2 </li></ul><ul><li>Leuconostoc mesentroids, Streptococcus faecalis, Pediococcus cerevisiae </li></ul>FERMENTED FOODS
