- Below is shown a growth curve for an E. coli culture. As indicated, the culture was incubated in the absence of a carbon source for 2 hours until Glucose and Lactose were added; Glucose was used up after 5 hours, and Lactose was used up after 8 hours. During the time-course, you take four samples, labeled A-D, after 1, 3, 7 and 9 hours, respectively, as indicated under the graph. Assuming there is cAMP present at t=0, for each sample identify whether CAP and/or the Lac Repressor would be bound to the DNA, and explain why.arrow_forwardBelow is shown a growth curve for an E. coli culture.

- Illustrate a hypothetical graph showing the growth progression of lactic acid bacteria and coliforms in a successful burong mustasa fermentation. Remember to label your graph properly.arrow_forwardYou record the following results of a nitrate reductase broth that was inoculated with an unknown bacteria species and incubated for 48 hours. Step 1: Look for a gas bubble. There is a gas bubble. (You know that your unknown bacteria can ferment glucose. You are not sure if the gas is nitrogen gas or carbon dioxide gas, so you go onto step 2). Step 2: Add reagent A and B. There is no color change. Step 3: Add zinc. The broth turns red. What is your interpretation of this unknown bacteria? What type of gas is probably the product of this reaction and is in the Durham tube?arrow_forwardDuring cheese production, LAB convert lactose to lactate and casein (milk protein) to amino acids. Lactate and amino acids then become the substrates for further microbial growth, which results in aroma production and deacidification of the cheese. The yeast Yarrowia lipolytica grows on the surface of many cheeses; it is capable of both lactate and amino acid catabolism. When grown on a lactate plus amino acid medium, Y. lipolytica preferentially consumes amino acids. Amino acid degradation results in the release of ammonia, which increases the pH. Draw a flow chart that shows the LAB fermentation of milk, followed by the growth of Y. lipolytica. Indicate which substrates are consumed first and what happens to the pH. Based on this simplified scenario, why do you think most cheeses involve the activity of more than one yeast species?arrow_forward
