Chapter 17, Problem 6CHI
Zymomonas mobilis is a Gram-negative bacterium that is used to make ethanol on an industrial scale. There is great interest in enhancing and expanding this microbe industrial uses. This prompted a group at the University of Hong Kong to develop a new E. coli–Z. mobilis shu vector. To do so, they started with a plasmid naturally found in some Z. mobilis strains. What genes and gene elements might the researchers need to add in order to construct a successful shuttle plasmid? What genetic elements do you think were added to obtain high-level expression of heterologous genes? Finally, how do you think they determined the copy number of the resulting shuttle vector in E. coli and in Z. mobilis?

You are a graduate student working to construct a single gene knockout library of Leptospiria kirschneri, one the causative agents of leptospirosis. You are looking for single gene mutants which disrupt the bacterium’s spirillum shape to determine what role this rare cellular morphology may play in disease development and progression. Using an appropriate donor strain, you introduce the plasmid shown into L. kirschneri. L. kirschneri is not able to replicate the plasmid. The repeat regions are denoted on the plasmid map as vertical black lines, the transposase is denoted as tnp, and kanamycin kinase is denoted as aph. The larger of the two regions is transposed. Following selection and counter-selection, you isolate several non-spirillum colonies, which you use to infect juvenile piglets. Most of the infected piglets develop leptospirosis. Isolating L. kirschneri from these animals reveals that it has regained its spirillum morphology. What is a likely explanation for this reversion of…

You are studying a type of bacteria isolated from the acidic water runoff of a mining operation. You subject two batches of the same bacteria type to different environmental growth conditions. One batch is grown at pH 2, while the other is grown at pH 7. All other environmental parameters are kept identical between the two batches. You then collect their proteins and run a Western blot using an antibody that binds to a proton efflux pump protein (which actively expends energy to pump protons out of a cell). How would you characterize the information obtained in this experiment? What does it tell you, and why is that potentially valuable information?
Streptococcus pneumoniae is a Gram-positive bacterium that colonizes the mucosal surface of the upper respiratory tract in humans. The presence of this bacterium in the nose and throat is widespread in the population, and in most people, colonization with Strep. pneumoniae is asymptomatic. The figure attached shows a comparison of in vitro growth curves of the wild-type strain of Strep. pneumoniae, as well as a Strep. pneumoniae mutant strain with a defect in one bacterial gene. The graph on the right shows the growth curve following addition of lysozyme during the logarithmic phase of bacterial growth.
Which statement could account for the data in these graphs?
Strain B is wild-type Strep. pneumoniae, and strain A is a mutant that cannot modify its peptidoglycan to be lysozyme-resistant.
Strain B is wild-type Strep. pneumoniae, and strain A is a mutant that that expresses increased levels of LPS.
Strain A is wild-type Strep. pneumoniae, and strain B is a mutant that cannot modify its…

- You are attempting to propagate bacteriophage of Bacillus cereus using a liquid batch culture. A growing culture of B. cereus is inoculated with your bacteriophage. The day before you tested the bacteria and the phage batch and they both behaved as expected. You made sure that all containers are labeled appropriately. Immediately after inoculation, you take a sample but are unable to detect any bacteriophage in the media. What is the most likely explanation? O You used the wrong bacteria or the wrong bacteriophage. There is an issue with the phage batch. O There is a problem with your bacterial culture of B. cereus. O It is too soon. The bacteriophages are still replicating and assembling inside the bacterial cells and are therefore not detectable in the growth media.arrow_forwardBacterial conjugation has medical consequences. For example, certain plasmids contain genes that code for toxins. The causative agent of a deadly form of food poisoning, E. coli 0157, synthesizes a toxin that causes massive bloody diarrhea and kidney failure. This toxin is now believed to have originated in Shigella, another bacterium that causes dysentery. Similarly, the growing problem of antibiotic resistance is partly attributable to the spread of antibioticresistant genes among bacterial populations. Antibiotic resistance develops because antibiotics are overused in medical practice and in livestock feeds. Suggest a mechanism by which this extensive use promotes antibiotic resistance.arrow_forwardWhen T4 phage isolated from E. coli strain B infect E. coli strain K, what will be the EOP (efficient of plating)?
