- 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.Pseudomonas aeruginosa is capable of aerobic respiration and anaerobic respiration but not fermentation. It can produce H2Sdoes not produce tryptophanase, and is motile by a flagellum . Based on the above characteristics, describe your expected results for Pseudomonas aeruginosa in a SIM deep .Escherichia coli O157:H7 is a foodborne pathogen and can cause serious illness in humans by producing toxins that can severely damage the lining of intestines and kidneys. What are the oxygen requirements of coli? What result would you observe in the MTM agar deep test? Explain. Research on the growth requirements of this bacterium is required. What is the role of oxygen and cytochrome c oxidase in aerobic respiration? Why does the nitrate reduction tube turn red after the addition of zinc? Clostridium tetani is a common soil bacterium and causes tetanus. Would you expect tetani to possess the enzyme catalase? Explain. Research on the growth requirements of this bacterium is required.
- In fermentative metabolism, a microbe produces ATP by: oxidizing NADH to form the proton motive force more than one of the answers is correct generation of a proton motive force by transfer of electrons to oxygen substrate level phosphorylationIn anaerobic respiration, what will happen if a bacterium uses nitrates as the terminal electron acceptors? nitrogenlaxation nitrification denitrification both nitrogen fixation and nitrificationImagine you are trying to use an organism to remove organic matter in a wastewater treatment plant (i.e., poop). You would like to maximize the amount of waste consumed while also minimizing the amount of cells produced. Assuming these organisms exist and all other things are equal, what combination of chemoorganotrophic organism and environment would make the most sense to use? An organism that only has the Entner-Duoduroff pathway under anaerobic conditions. This was a trick question – the organism would have to be a chemolithotroph since it is consuming a chemical. An organism that only has the Entner-Duoduroff pathway under aerobic conditions. An organism that only has the Embden Meyer Parnas pathway under anaerobic conditions. An organism that only has the Embden Meyer Parnas pathway under anaerobic conditions.
- A chemolithoautotroph is respiring using only iron (Fe3+) and nitrite (NO2-). This bacterium does not consume organic molecules. Describe a result of this organism’s metabolic pathways that could be beneficial to another organism (of any type) living in close proximityKombucha 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.In what conditions would a microbe skip over the conversion of alpha-ketoglutarate to succinyl- CoA? It's highly NAD+ limited It's highly carbon limited It's highly ATP limited It's highly NADH limited
- 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…Chemolithotrophs meet their energy needs by oxidizing organic food molecules. True False Which of the following events does not occur during the energy-investment phase of glycolysis? Hexokinase catalyzes the transfer of a phosphate group from ATP to glucose to form glucose-6-phosphate. Phosphofructokinase catalyzes the isomerization of glucose-6-phosphate to fructose-6-phosphate. Fructose-bisphosphate aldolase cleaves Fructose-1,6-bisphosphate into two different three-carbon sugars. Dihydroxyacetone phosphate can be converted to glyceraldehyde-3-phosphate with the help of the enzyme triose phosphate isomerase.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.
