E. coli has a doubling time of 20 minutes, if a piece of meat is contaminated with 1 E. coli cell how many cell would it contain after 12 hours? What about 24 hours?
E. coli has a doubling time of 20 minutes, if a piece of meat is contaminated...
E. Coli has a doubling time of 20 minutes under certain growth conditions. Compute the biomass of E. coli (in pounds) that will accumulate when a single cell of E. coli grows exponentially for 50 hours in these conditions, assuming that nutrients are not limiting. Show your work. (An E. Coli cell has a mass of 10-12gram/cell).
Help The doubling time of E. coli is 20 minutes in media containing methionine. If the media lacks methionine the doubling time is 30 minutes. Draw and label comparative growth curves. E. coli was used as the negative control for Gram Staining in Lab. Describe it. Use a diagram or diagrams and label it.
a) During the exponential phase of bacterial growth, the lab strain of E. coli has doubling time of about 30 minutes. If you start with 10,000 cells per mL of culture, and let them grow exponentially 2 hours in a flask, what is the final density of the culture? Show and explain your calculations. b) If you plated a100μL of 1:1000 dilution that culture (after it had grown in a flask for 2 hrs) how many colonies would you expect...
A culture of 10 bacteria of Escherichia coli has a generation time of 30 minutes at 35 degrees Celsius. After 5 hours at this temperature, how many bacteria would you expect to see?" a. "10,240" b. 50 c. "1,000" d. 320 e. "10,000,000,000"
If escheria coli has a generation time of 20 minutes, will you be able to construct a growth curve from the following data ? Initial time 0 absorbance 0.05 cell number per every mL 1.0x107 . Ending Time 20 minutes absorbance 0.07 cell number 1.0x107 ?
The doubling time of a bacterial population is 20 minutes. After 120 minutes, the bacterial population was 60000. What was the initial population of bacteria? Round your answer to the nearest whole bacterium. Using your rounded answer from above, find the size of the bacterial population after 5 hours. Round your answer to the nearest whole bacterium.
The doubling time of a bacterial population is 20 minutes. After 100 minutes, the bacterial population was 80000. What was the initial population of bacteria? Preview Round your answer to the nearest whole bacterium. Using your rounded answer from above, find the size of the bacterial population after 4 hours. Preview Round your answer to the nearest whole bacterium.
3. You inoculate 1 liter of medium with an E. coli culture to an initial cell density of 104 cells/ml. The culture grows exponentially with a generation time of 20 minutes. What is the culture density after 24 hours?
Calculate how long (in hours) it will take for a culture of E. coli to reach the mass of the Earth and Jupiter ifyou start with one cell and the doubling time is 20 min. Consider each cell to be 1 picogram.
If E. coli is grown under conditions that maintain a generation time of 80 minutes and the cells are the quickly transferred into a new medium that allows a generation time of 40 minutes? 1. How would that affect DNA polymerase? 2. DNA replication process? 3. DNA division? 4. Will generation time change?
