Microbiology and Bacteria Essay Example for Free

Microbiology and Bacteria EssayMicrobiology is the study of microorganisms which must be viewed with the aid of a microscope or electron microscope. The importance of microbiology includes used in biomedical research, creation of medicines, environmental applications and new research tools. Disease causing organisms include protists, bacteria, computer viruses and other microorganisms. Bacteria are important for fixing N2 in a utile form for plants. Bacteria and some fungi are important in decomposition and recycling of raw materials.Industry applications of microbiology waste management, food industry, mining, medicine, research and biotechnology. 1660s Robert Hooke observed microorganisms for the first time with a microscope and coined the term cell. 1632-1723 Anton van Leeuwenhoek credited with having observed the first bacteria. 1828-1898 Ferdinand Cohn developed the first classification scheme establish on bacteria shape. Cohn detailed and described the life cycle of Baci llus. Cohns Classification SystemSphaerobacteria are spherically shaped.Microbacteria are rod shapedDesmobacteria are filamentousSpirobacteria are spiral shaped1822-1895 Louis Pasteur Defined pasteurization to prevent spoilage of food by bacteria, develop vaccines and disproved the scientific dogma of Spontaneous contemporaries. He defined Germ Theory and demonstrated that germs were responsible for disease. 1843-1910 Robert Koch identified anthrax and developed agar growth medium. Kochs postulates was a systematic mode to establish the microbial cause of disease. Ignaz Semmelweis was the first to recognize the need for good hygiene during medical procedures. The first to identify nosocomial infections. 1827-1912 Joseph Lister developed bactericidal methods for use in surgery and medicine.1854-1915 Paul Ehrlich developed chemotherapy to cure infectious diseases and discovers antibiotics to treat sleeping sickness and syphilis. 1881-1951 Alexander Fleming discovered penicillin and lysozyme. 1864-1920 Dmitri Ivansvski discovered the first virus which is known as the tobacco mosaic virus (TMV). 1952 Hershey Chase Experiments identified that DNA was the genetic material of bacteriophages. Hershey Case Experiment using phage radioactively labeled with P32 (DNA) or S35 (protein) they infected bacteria cells. They found the P32 inside the bacteria not S35.Recommendations for Success in MicrobiologySuccessful completions of general biology 2 semesters fellowship of basic chemistry and biochemistryBasic understanding of classificationReview lay extinct of text book used in the course.Read and master learning objectives laid out in the text book.
