Lecture 9: Microbial Nutrition 1. Anabolism/Catabolism (ABCD—Anabolism Builds Catabolism Destroys) 2. Difference between Anabolism and Catabolism and Oxidation and Reduction a. Canabolism—breaks down large molecules to small for energy b. Anabolism—builds up small molecules with energy to large molecules (for storage) c. Oxidation—loses electrons, gains oxygen d. Reduction—gains electrons, loses oxygen e. Ex: CO2 CH3OH CH4 f. Reduced oxidized 3. Understand the difference between heterotrophs and autotrophs and sources of carbon a. Metabolism i. Carbon Source—building biomass/biomolecules (occasionally also e- donor) 1. Heterotrophs (other-feeding) (we are heterotrophs) a. Use organics to supply carbon (i.e. glucose) b. Carbons source also typically supplies H and O c. Carbon source also supplies energy 2. Autotrophs (self-feeding) a. Uses CO2 as its sole carbon source b. Carbon source does not supply energy 3. Mixotrophs—mixture of hetro and autotrophs ii. Electron Donor—energy source (occasionally also carbon source)
