5. Making curd and Bread Medicinal use of Microorganism Increasing Soil Fertility Cleaning the Environment Vaccine Commercial production of alcohol and wine Usage of Microorganism

6. Harmful effects of Micro organisms

7. Microbes are tiny living things that are found all around us and are too small to be seen by the naked eye.  They are also known as microorganisms or microscopic organisms as they could only be seen under a microscope. They live in water, soil, and in the air. Microbes can be useful as well as harmful.  Certain microbes cause severe infections and diseases and can also spoil food and other materials.  Microbes play an important role in maintaining environmental balance. What is meant by microbes?

8. Types of Microbes Microorganisms are divided into different types: Bacteria Fungi Viruses Archaea and Protists

9. Types of Microbes : Bacteria Bacteria are unicellular, microscopic, prokaryotic microbes that contain no true nucleus. They have a flagellum that facilitates locomotion. Bacteria are of different types depending on their shapes and sizes. For eg., spherical-shaped bacteria are known as cocci; rod-shaped bacteria are known as bacilli; spiral-shaped, spirilla, etc. They reproduce through binary fission. Few bacteria such as Rhizobium are involved in nitrogen fixation. Bacteria's can be harmful as they can cause harmful disorders such as Tuberculosis BACK

10. Types of Microbes : Fungi Fungi (mushroom, molds, and yeasts) are eukaryotic cells (with a true nucleus). These can be unicellular or multicellular in nature and are found in wet areas These are heterotrophic and cannot synthesize their own food. Yeasts, moulds, mushrooms are some of the important fungi. Few fungi are harmful and cause fungal infections like ringworm. The others are used in making antibiotics like penicillin. Fungi such as yeast are used in all baking industries and also in the beer and wine industries BACK

17. Archaea constitutes a  domain  of single-celled organisms. Earlier, Archaea were classified as bacteria, but now it is outdated as it has been found that they both have different biochemistry and different evolutionary history.   They are single-celled organisms that comprise cells with distinct properties that make them unique from the other two domains of life, namely Eukaryota and Bacteria . Basic Facts They live in extreme environments (like hot springs or salty lakes ) Normal environments (like soil and ocean water Some have a flagella that aids in their locomotion Types of Microbes : Archaea

18. The hierarchy of  biological classification 's Main taxonomic ranks

19. Some weird things about this kingdom: Most don’t need oxygen to survive They can produce ATP (energy) from sunlight They can survive enormous temperature extremes. They can survive high doses of radiation (radioactivity ) They can survive under rocks and in ocean floor vents deep below the ocean’s surface. They can tolerate huge pressure differences Methanogens are the only archaea that have been identified in humans, despite human contact with other archaeal types Anaerobes usually act as opportunists Types of Microbes : Archaea

20. Protists are simple eukaryotic organisms that are neither plants nor animals or fungi . Protists are unicellular in nature but can also be found as a colony of cells. Most protists live in water, damp terrestrial environments or even as parasites. Types of Microbes : Protists Classification of  Protista : Kingdom Protista is classified into the following Protozoa Slime Moulds Chrysophytes, Dinoflagellates and Euglenoids (Algae) Chrysophytes : Yellow –Green Algae
