- The following four chemicals commonly found in defined growth media contain all of the necessary atomic macronutrients, namely C, O, N, H, S and P, which microbes require: glucose (C6H12O6), K2HPO4, MgSO4.7H2O, and (NH4)HPO4. Part a. Create a simple diagram to map which growth media chemical contributes atoms to which of the four biological macromolecules (amino acids, polysaccharides, lipids, and ribonucleic acids). Part b. Consider a cell culture broth that originally (before inoculation with cells) contains 5.0 gr/L glucose (C6H12O6), 1.2 gr/L K2HPO4, 0.3 gr/L MgSO4∙7H2O, and 1.0 gr/L (NH4)HPO4. Create a table showing how much of each of the different atoms (C, H, O, K, P, Mg, S, N) are available for incorporation into cell macromolecules (assume 50% of the glucose is catabolized, while the remainder goes for energy (respiration). Express your answers with units of grams of atomic species / liter of culture broth.arrow_forwardExplain the concepts of TDT (Thermal Death Time) and TDP (Therma Death Point), and discuss one example of how these measurements can be modified to produce food for human consumption that is free of microbial contaminants yet still tasty. Use examples. What are the minimum TDTs for vegetative cells and endospores?arrow_forwardImagine you are trying to use an organism to remove organic matter in a wastewater treatment plant (i.e., poop). You would like to maximize the amount of waste consumed while also minimizing the amount of cells produced. Assuming these organisms exist and all other things are equal, what combination of chemoorganotrophic organism and environment would make the most sense to use? An organism that only has the Entner-Duoduroff pathway under anaerobic conditions. This was a trick question – the organism would have to be a chemolithotroph since it is consuming a chemical. An organism that only has the Entner-Duoduroff pathway under aerobic conditions. An organism that only has the Embden Meyer Parnas pathway under anaerobic conditions.
