Consider the following graph depicting the population growth of bacteria in an "ideal" laboratory created condition. Explain what conditions would allow for a population to grow exponentially like in this example, and why this is unlikely to occur naturally in the wild. Population (number of bacteria) 35000 30000 25000 20000 15000 10000 5000 0 Population Growth of Bacteria in Ideal Conditions Time (hours) 5

In a series of infection experiments, a researcher discovers that the ID50 value for the infectious bacterium Parasiticum mucoides is 2,000, and that the ID50 for another infectious bacterium, Donoteatum thisbacterium, is 150. Given these data, a person exposed to 1,000 bacteria of each type would be more likely to be infected by which bacterium? There is no way to know given the information provided Both infections are equally likely Donoteatum thisbacterium Parasiticum mucoides
Which of the following is true about the organism which grew at both 37°C and 4°C in the figure below? 4°C 37°C 64°C 25°C This organism will not survive in the human body O The organism can be propagated through refrigerated food O Heating food to 350 degrees Fahrenheit (or 176 degrees C) in the oven will not kill the microorgansim The organism can grow in the human body
In the experiments below, different prokaryotic cells were grown in broth cultures in the presence or absence of an antibiotic (either vancomycin or polymixin) After 1 hour, cells were rinsed, and the percent of bacteria that survived was determined. According to the data, which experiment (A or B) was done with vancomycin and which was done with polymyxin? Explain your reasoning in both cases. 100 0 A Bacillus E. coli with antibiotic without antibiotic B Methanoge n 100 Bacillus E. coli Methanogen
Bacteria grown in a lab experience what is called an 'exponential phase' of population growth. Suppose that, during this phase, a colony of Escherichia coli you are growing has a per capita growth rate, r, of 0.0347 per minute. If the size of your colony at the start of the exponential phase is 0.25 billion cells, then approximately how large will it be in 120 minutes?
The generation time of a bacterial culture that produces two generations per hour is: a. Equal to that produces three generations per hour bLesser than that produces five generations per hour than that produces three generations per hour Lesser than that produces four generations per hour Greater than that produces three generations per hour
Answer the following questions: 1.What is the advantage of computing the arithmetic number? the logarithmic number? 2.What is the importance of knowing the growth dynamics of bacteria microorganisms in disease control, food and industrial product?
For an estimation of microbial population experiment, you obtained the following results: A. 1000X dilution with 0.1 mL sample volume - 470 colonies B. 10000X dilution with 0.1 mL sample volume - 250 colonies C. 100000X dilution with 0.1 mL sample volume - 100 colonies D. 1000000X dilution with 0.1 mL sample volume 12 colonies For each set of results, determine if the samples are countable plates, and for only the countable plates, calculate the CFU/mL for those plates. For plates that are not countable, please state that and do not perform the calculation (please note that calculating the CFU/mL for a plate that is not countable will be marked as incorrect).
Background info: The cyanobacterium Arthrospira platensis, colloquially known as Spirulina is/was a popular health food/supplement because it is extremely rich in amino acids and vitamins. However, these cyanobacteria also happen to be extremely good at absorbing lead, which means that these supplements are often contaminated with toxic amounts of heavy metals. One suggested application for these cyanobacteria is in bioremediation systems for industrial/mining wastewater contaminated with lead Question: The way that this application would work is that you’d have a sealed concrete pond full of the cyanobacteria that wastewater would flow into and then as the wastewater flows out the other end of the pond, the cyanobacteria are removed. How would this work to remove lead from the water?
