MCB 2004 Lecture Notes - Lecture 3: Haemophilus Influenzae, Cell Wall, Protozoa
Document Summary
Influenza: first draft of human genome published in 2000. 6 major groups of microorganisms: bacteria: Use organic chemicals, inorganic chemicals and photosynthesis for energy: protozoa. Move by pseudopods (false feet), cilia (short appendages) or flagella. Produce molecular oxygen and organic compounds (due to being a photosynthesizer: fungi. Use organic chemicals for energy: archaea. Methanogens: produce methane as a waste product from respiration. Extreme thermophiles: live in hot sulfurous water (hot: viruses (not living) springs) Only be seen with an electron microscope because they are. Core is sourrounded by protein coat enclosed in an envelope. Genome is surrounded by protein coat called capsid. Viruses are replicated only when living in a living host (intracellular parasites) Microorganisms produce: fermented foods (bread/cheese, industrial chemicals (ethanol/acetone, medicine (insulin/vaccine, decompose organic waste, producers in photosynthesis, a few are disease causing. Knowledge of microbiology: decrease growth: prevent food spoilage, prevent disease, prevent contamination, increase growth: make fermented food, medicine, recycle waste.
