1. Clostridium butyricum does not appear to have superoxide dismutase (SOD) and catalase enzymes. How would the growth of C. butyricum in oxic conditions compare to its growth in anoxic conditions? On this basis, what is the aerotolerance category of C. butyricum? 2. Citrobacter freundii is a facultatively anaerobic bacterium. Why would you expect this bacterium to grow better (i.e. form larger colonies) in an oxic environment than in an anoxic one? (as a hint, do some research on the “Pasteur effect”)

Penicillin, an antibiotic, inhibits the formation of cross-links between sugar groups in peptidoglycan. Bacteria treated with penicillin should be: a. acrobic. b. anaerobic. c. Gram-negative. d. Gram-positive. e. flagellated.
Ammonification is the process by which. ammonia is released during the decomposition of nitrogen-containing organic compounds ammonium is converted to nitrite and nitrate in soils nitrate from soil is transformed to gaseous nitrogen compounds such as NO, N2O, and N2 gaseous nitrogen is fixed to yield ammonia
4) You are interested in the total bacterial load of the bat guano. In order to determine this, you go back to your original broth culture and prepare a dilution series. You then spread 100 ml of each dilution onto 3 separate plates. You obtain the following results: Plate 1, 10 -1 dilution: 362 colonies Plate 2, 10 -3 dilution: 76 colonies Plate 3, 10 -5 dilution: 8 colonies. Based on your results, calculate the CFUs/ml in your original broth culture. show your work
If you altered the conditions under which bacterial growth normally occurs (i.e. increase the temperature of incubating a culture from 35 to 40°C), what effect would this have on the bacterial growth curve of the organism under study?

Pseudomonas bacteria have porin proteins, are resistant to the chemical triclosan, and survive and can even multiply in quaternary ammonium compounds. True or False?
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?

(D)State the temperature class for Escherichia coli, Bacillus sp, Aeromonas sp, Micrococcus luteus, and suggest their optimum growth temperature. 2 (a)Why is dilution important when determining microbe number? (B)How does a decrease in dye colour intensity affect the microbe ? (C)State the possible sources of error if plate counts and colour intensity of dilutions are incorrect or Precautions taken to prevent this from happening. ( this is not a graded assignment)
1) would you describe the contents of the soil-inoculated broth as being a “pure culture”? Why or why not? 2) How did the uninoculated broth differ in appearance from the broths inoculated with E. Coli and M. Luteus? And then how could you tell if a supposedly sterile, uninoculated broth was contaminated? Please explain in detail and highlight the important parts cuz I am confused and need help! Thanks
