As a class, we added several different reagents to ourWinogradsky columns. We also made onecontrol-column that had nothing added to it (aside from sedimentand water). Everyone added paper towels (but at varying depths),and sulfate to the bottom of their columns. The rest of thetreatments are listed below. Please indicate what types oforganisms you might enrich with that type of treatment and why, orhow and why that treatment might result in a different type ofgrowth rate or metabolic rate. (Possible organisms arelisted but not limited to: Oxygenic phototrophic microorganisms,Diatom, Cyanobacteria, Filamentous algae, Purple sulfur-oxidizingphototrophic bacteria, Green sulfur-oxidizing phototrophicbacteria, Aerobic heterotrophs, Fermenting bacteria,Sulfate-reducing bacteria...)
