Explain how the microbe in your selected food undergoes fermentation biochemically speaking, and how does this impacts the food quality?
The example I chose for the fermented food is Yogurt.
Two microorganisms that use naphthalene as a food source have the same Umax but different Ks values for naphthalene. If both types of microorganisms are inoculated at the same cell density into a liquid culture containing naphthalene as the sole carbon source (i.e. the only food source), which microorganism will outcompete the other: the one with the higher Ks or the one with the lower Ks. Why?.
If a biotechnologist wishes to obtain a primary metabolite, they will harvest the organism/media during log phase. If a biotechnologist wishes to obtain a secondary metabolite, they will harvest the organism/media during stationary phase. Can you explain this distinction regarding the metabolism of the cell at these two different batch culture growth phases?

- c) Pasteurization is a technique that uses temperatures of about 72°C to neutralize potential pathogens in foods. a. Justify the effect does this temperature have on the enzymes and cellular metabolism of pathogens. b. Argue why does the heat of pasteurization kill some microorganisms yet fail to affect thermophiles?arrow_forwardWhat are the general concepts of microbial metabolism and explain each concepts? (Give at least 4 concepts)arrow_forwardOxygen is always beneficial to micro-organisms. Discuss this statement in the context of factors that influence microbial growth.arrow_forward
- 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_forwardGive at least 2 advantages (and explain) of using microorganisms as industrial inputs.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_forward
- If the result of an unknown bacteria is “poor growth” and “red growth,” can this result be interpreted as “organism does not ferment mannitol?” Explain why or why not. If the result of an unknown bacteria is “good growth” and “yellow growth,” is the unknown bacteria more likely Staphylococcus aureus or Staphylococcus epidermidis?arrow_forwardExplain the reasons why the Poon Choi is the high risk food for the elderly?

Describe one laboratory media that can cultivate microbes with various oxygen requirements.

Proteus vulgaris. Salmonella typhimurium. Alcaligenes faecalis. Shigella flexneri. 2). If Citrate is a sugar and fermentation generates an acid, why does the BromThymol Blue indicator in the media turn blue and not yellow? 3). Why is Salmonellosis associated with eggs? Can you get Salmonellosis from other animal sources?arrow_forwardGive an example of a chemicals or drugs that is converted to an active metabolite by sulfonation; other than minoxidil.arrow_forward
