A bacterial strain is growing exponentially. At 1:00pm the titre of the culture is 2x10^3 cells per ml. Three hours later, the culture is still growing exponentially and the titre is 4x10^4 cells per ml. How many generations have elapsed, what is the generation time, and what will the titre be at 9:00pm
A bacterium is inoculated into a medium containing two carbon sources, one of which is the bacterium’s preferred carbon source. The resulting growth curve shows two lag phases. Explain this phenomenon. What is this type of growth called? Include a diagram of what the growth curve would look like and indicate the usage of each carbon source.
The proteobacteria in the genus Pseudomonas are important spoilers of food. The rate at which food spoils is dependent on temperature. The data in the Figure show the relationship between the square root of the growth rate (how fast the population is growing per day; unitless) and the temperature of the culture. Does typical refrigeration (temperature lowered to 4C) appear sufficient to limit growth rate compared to room temperature (20C)?
make a graph out of this t = time of growth of bacteria in mins y = number of bacteria
Show a growth curve graph of the two types of bacteria binary fission and budding which one grows faster using a spectrophotometer please put time and number of bacteria in numbers dt to sale
Which of the following include the correct order of phases of a typical bacterial growth curve? log, lag, stationary, decline/death lag, log, stationary/decline, death lag, log, stationary, decline/death log, lag, decline/stationary, death
Show a growth curve graph of the two types of bacteria which one grows faster using a spectrophotometer
How would a limited food supply affect the bacterial growth curve? The lag phase would be longer than if the food supply were unlimited. The log phase would be shortened. The culture would not enter a death phase but would remain stationary indefinitely. The death phase would be shortened.
The agent of gas gangrene is classified as an based on its oxygen sensitivity so in addition to antibiotics and debrideent, hyperbaric oxygen is commonly used in the treatment of gas gangrene. This organism can persist in the outside environment under extreme harsh conditions which include the presence of high levels of atmospheric oxygen because it is able to form an (seen as the absence of color in the Gram stain) which will germinate when introduced into environments such as deep muscle tissue with minimal levels of oxygen, lots of water, and lots of nutrients.
