- 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”)Kombucha requires two fermentation steps. The first one is partly aerobic and partly anaerobic. The aerobic growth occurs because the kombucha is allowed to brew exposed to oxygen. Where is the anaerobic growth occurring in the first fermentation step? The second fermentation step is the step in which we add the kombucha to a sealed bottle therefore I'm confused as to where it can occur before we seal it.Pseudomonas aeruginosa is capable of aerobic respiration and anaerobic respiration but not fermentation. It can produce H2S, does not produce tryptophanase, and is motile by a flagellum. Based on the above characteristics, describe your expected results for Pseudomonasaeruginosa in a SIM deep.

- In aerobic respiration, cells generate heat as they grow. The amount of heat generated by cells is proportional to the amount of oxygen they consume. Accordingly, it was found that 460 kJ is generated per gmol of O2 consumed. Suppose that you need to choose a fermenter for optimal growth of Bacillus subtilis cells. It is known that the maximum oxygen demand of B. subtilis is 100 mol m3 h1. A vendor offers you a reactor with a cylindrical shape (2.8 m in diameter) and 15 m³ volume. The reactor includes a cooling coil with 30 m length and a pipe diameter of 6 cm, through which. For practical purposes, power input by the rotating impeller inside the bioreactor can be neglected. Does this reactor meet the cooling requirements of your production process? Note: If you think you need more information than you are provided with here to solve this problem, use online resources to find the required information. In this case, please state your source clearly. Note: You may assume that the…8. Anaerobic respiration is different from aerobic respiration in that... a) in anaerobic respiration oxygen is not the final electron acceptor at the end of the electron transport chain. b) anaerobic respiration can only produce 2 ATP. c) anaerobic respiration only includes the metabolic pathway of glycolysis. d) anaerobic respiration is an anabolic reaction type.Fermentation will occur under anaerobic conditions only Sometimes the condition is temporary, resulting in lactic acid fermentation Once an oxygen debt has been repaid, fermentation will stop under anoxic conditions only Sometimes the condition is temporary, resulting in lactic acid fermentation Once an oxygen debt has been repaid, fermentation will stop under anoxic or anaerobic conditions Sometimes the condition is temporary, resulting in lactic acid fermentation Once an oxygen debt has been repaid, fermentation will stop under anoxic or anaerobic conditions Sometimes the condition is permanent, resulting in lactic acid fermentation
- I need to find two gram positive and two gram negative pathogenic bacteria that may be classified as being facultative anaerobes. What tissues or organs do these bacteria target in the human body? Why is it to their advantage to be able to use either aerobic respiration or anaerobic respiration/fermentation?Yeast are facultative anaerobic organisms that can make ATP by aerobic respiration if oxygen is present, but are also capable of switching to fermentation under anaerobic conditions. For thousands of years, humans have used yeast, such as Saccharomyces cervesisiae, to ferment grapes (starch sugar) to make wine (alcoholic beverage). Four batches of wine were made following the contents and conditions listed in the table below, Contents and Conditions of Four Batches of Wine Yeast Solution Water Grape Solution Batch Added Container (L) (L) (L) Lid 1 40 0.0 8 оpen 2 40 0.2 8 closed 40 0.2 8. оpen 4 40 0.2 closed 9. The yeast (Saccharomyces cerevisiae) would produce the greatest amount of ATP is the batch of wine numbered 1 4 D. The highest alcohol (ethanol) content would be found in the batch of wine numbered 02 3What is the role of oxygen in aerobic respiration? What type(s) of metabolism can occur in the absence of oxygen? Name two enzymes that are present in obligate aerobes but lacking in obligate anaerobes. What is the function of each enzyme Describe the difference between the appearance of surface and subsurface colonies in a pour plate.
