The study of the natural world.B. Scientfic Method1. observe2. come up with a hypothesis (a guess)3. test the hypothesis using experiments4. if the predicton matches the results of the experiments, th hypothesis becomes a theorya) theory: a framework within which observatons are explained and predictons are made5. if a theory is not disproved it becomes a lawa) laws are very rareThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.C. Ockhams’s Razor1. the simplest theory is probably the correct one2. it is based on the least amount of assumptonsII. What is microbiology?A. the study or organisms too small to see with the naked eye1. circle bacteria: cocci2. rod bacteria: bacilli3. curved bacteria: spirochetesB. branches of microbiology1. bacteriology: study of bacteria2. mycology: study of fungi3. algology: study of algae4. protozoology: study of protozoan5. virology: study of virusesC. Microbes in our lives1. a few are cause disease (pathogenic)2. decomposers3. are producers in the ecosystem by photosynthesis4. produce industrial chemicals like ethanol and acetone5. produce fermented foods like vinegar, cheese, and bread6. produce products used in manufacturing and disease treatmentIII. History of microbiologyA. 1665: Hooke first observed cellsB. 1857: Pasteur-fermentaton1. Pasteur was the father of microbiology2. How was Pasteur lucky with his experiments?a) He was lucky because there were no endospores in the broth- endospores: higly protected cells that can resist high temperatures and pressuresC. 1861: Pasteur- disproved spontaneous generatonD. 1864: Pasteur-
