Why do you think most bacteria grown in labs are mesophiles with a pH optimum for growth near 7.0, do you believe that it is representative of bacteria on earth? What problems would this cause.
Step by step
Solved in 2 steps
- You have a culture of bacteria with an unknown number of bacteria in it. You have at your disposal 10 1-mL pipettes, 3 dilution bottles that hold up to 100mL of volume, 3 test tubes that hold up to 10mL of volume, a graduated cylinder, an unlimited supply of distilled water. Explain how you would set up a 1: 10,000,000 dilution of your culture.A certain medium has the following composition: Glucose 15 g Yeast extract 5 g Peptone 5 g KH2PO4 2 g Distilled water 1,000 ml Tell what chemical category this medium belongs to, and explain why this is true. How could you convert Staphylococcus medium (table above) into a non-synthetic medium? a. What kind of medium might you make to selectively grow a bacterium that lives in the ocean? One that lives in the human stomach? Why are intestinal bacteria able to grow on media containing bile?Pseudomonas bacteria have porin proteins, are resistant to the chemical triclosan, and survive and can even multiply in quaternary ammonium compounds. True or False?
- For a bacterium that prefers a neutral pH and has an optimal (best) growth pH of 7, how would growth of this bacterium at pH 4 most likely compare to growth at pH 7? Growth would be slower (or the bacterium might die) at pH 4 Growth would be faster at pH 4 Growth would be the same at both pH valuesYou use a spectrophometer and estimate the concentration of bacteria in a urine sample to be 4.6 x 10^5 cells/ml. Assuming you will plate 0.1ml of your samples, to what factor should you dilute your sample to get a countable number of colonies? Rearrange Original Cell Density formula to solve.Helicobacter pylori, a bacterium that causes stomach ulcers, can grow in medium with a pH above 5. It can survive but not grow in pH 2 medium as long as the medium contains Urea. You inoculate a pH 2 broth with 1,000,000 H. pylori and for 8 hours the organism did not grow. The next morning however, the medium has become quite turbid, suggesting that the organism has grown. Explain how this could happen. What phylum and class does this organism belong?
- Why do low concentrations of alcohol inhibit Gram-negative bacteria more than Gram-positive bacteria? Explain how the alcohol interacts with: 1) Gram-negative cell wall structures 2) Gram-positive cell wall structuresThe following data were obtained by incubating gram-positive bacteria in nutrient medium + disinfectant for 24 hours, then transferring one loopful to nutrient medium (subculturing). (+ = growth; - = no growth. a. Table 7.3, which disinfectant is the most effective at stopping bacterial growth? How can you tell? b. In Table 7.3, which disinfectant was bactericidal? How can you tell? c. In Table 7.3, which disinfectant was most effective against Salmonella? How can you tell? [Hint: look up Salmonella] Table 7.3 K.O. Subculture Doom Dilution Initial Subculture Initial 1:16 1:32 1:64 1:128 Mortum Sterl Dilution Initial Subculture Initial Subculture 1:16 1:32 1:64 1:128You are studying a new bacteria isolated from the soil by identifying the cellular structures that it makes. The presence of which of the following would indicate that your organism must be a Gram-positive bacterium? It has a cell wall with teichoic acids It has a polyhydroxyalkanoate storage granule It has an outer membrane with LPS It has a flagella
- Lead is a very toxic metal that is not easily degraded in the environment. Lead pipes, paint containing lead, car batteries, and even lead fishing sinkers are all potential sources for the release of lead into the environment. what possible strategy can be done for identifying bacteria that may play a role in degrading lead?What is G+C content of a bacteria? How it can be determined? Why it is not safe to assume that microorganisms with same G+C content belong to same species? How G+C content data is taxonomically valuable?Most bacteria require a water activity of 0.9 or higher to grow. A prolonged period of being dry usually causes loss of viability. How were there still living bacteria in many of the dried foods such as dried rice, dehydrated coconut flakes, raisins, etc.? Discuss.
