Unformatted text preview: Intro to Micro Introduction to Microbiology January 12, 2009 Microbiology The study of very small (microscopic) organisms. Microbiology- regular organisms that you can't see with the naked eye The study of the very small organisms that have macroscopic forms. Example : Algae, fungi, and worms Some Micro turn Macro i.e. algae seaweed Ex: mushrooms have microscopic filaments (spores) grow to macro Challenging subject: like foreign language Large vocabulary Many scientific names Many concepts Involves critical thinking skills Microorganisms Deep hidden secret; most people don't have microscopes. Great opportunity to study a subject that is intrinsically interesting to a great many people but they are totally ignorant about it. Microbes eat everything, including people. (like Pacman- eat everything) How they effect us? Very egocentric, keep environment balanced 1. They are important for recycling of matter in the environment 2. Bioremediation- process that microorganisms commits that they take something bad and make it good: i. Ex: bacteria that makes plastics, that can also degrade them ii. Microorganisms can not degrade radiation 3. They are used in the food, chemical and pharmaceutical industries. Examples: yoghurt- lactobacillis- has niches so it lives in your body and makes you healthy Soysauce- has aspergelosmicis Swiss cheese - has proprionobacter- gases make bubbles Examples: yoghurt, swiss cheese (gas makes holes), soy sauce, butter, antibiotics, steroids, chemicals (EtOH, acetone, citric acid, etc.) Concepts in Microbiology (Idea of "contagion" is old) • Greece: Aristotle (2350 years ago) told Alexander to boil water and bury fecal material to avoid disease caused by contagion o All is killed by boiling water, and bury fecal matter so flies don't spread the bad stuff o In underdeveloped areas they do not think the same way they poop everywhere • Middle Ages: Disease caused by "influences" of stars (ex: influenza) • Renaisance: o Idea of "spontaneous generation" prevalent. Even among good scientists- putrification (really from spore formers) • Spontaneous generation- things grew from things that are rotting o Redi (Italian): Meat in petri dishes, exposed some to air. Maggots appeared only in or on exposed plates. • Sealed glass- no maggots • Not sealed- maggots • Sealed with gauze- one or two maggots • Caused them to get over spontaneous generation o Van Leeuwenhoek (Dutch Merchant): Ground lenses and mounted them. Made simple (1 glass, 1 H20 lens) microscope; published scetched of "animacules" • Ex: Giardia, bacteria. Added to debate over "spontaneous generation" • Made microscopes and saw many amazing animacules (now called bacteria or protozoa), still thought there was spontaneous generation, sometimes heating killed sometimes didn’t. argument over spontaneous rising or not....
