Document Summary

Study guide 4 unit 3: microbes that use reduced sulfur compounds as electron donor for aerobic/anaerobic respiration. Indicated by red arrows in the diagram on the slide. Ets used to make a pmf, which is used to make atp. Typically the electron acceptor is o2 (aerobic respiration) or nitrate (anaerobic respiration) Sulfate reduction: microbes use sulfate as electron acceptor for anaerobic respiration. Indicated by green arrows in the diagram on the slide. Take sulfate and reduce it into h2s or just sulfur. Trophosome: trophosome contains sulfide oxidizing bacteria. Forgut fermenter: organism who has a larger forgut (more bacteria ferment here, better absorption is able to occur. Hindgut fermenter: organism that has a larger hindgut (where bacteria can ferment) Rumen: organelle that helps degrade cellulose in anaerobic bacteria, gut where many different types of microbes live, 1. Fermentation occurs: 5. production of scfa (vfa) feed animal, 6. gases are wastes (co2/methane) released to environment.
