Is it possible a bacterium that can only grow at the bottom of a tube of thioglycolate broth is also oxidase- positive? Why, or why not? Select one: a. Yes, it is absolutely possible. This bacterium is facultative anaerobic, so it uses oxidase to ferment glucose. b. No, it is not possible. It is an obligate anaerobe, and has no reason to have enzymes needed for aerobic respiration. O c. No, it is not possible. It can only use fermentation...

34) During Salmonella enterica gastroenteritis (acute inflammation of the stomach and intestines, often accompanied by nausea, vomiting, diarrhea, and abdominal pain), responding neutrophils of the human immune system generate an oxidizing environment that generates tetrathionate, a compound Salmonella uses as a terminal electron acceptor for anaerobic respiration. Most normal microbiota are unable to use this compound, instead relying on fermentation in this anaerobic environment. In the densely populated intestinal tract, this . A) slows the growth of Salmonella relative to...

14. Lab Exercise 5-1 is an interesting way to run these test tube experiments without oxygen - seal the tube with a layer of clear mineral oil on top (see the figure in the manual). Based on this figure and the Table of Results for this experiment, if the sealed tube is all green or slightly blue but the unsealed tube has any amount of yellow, what type of energy metabolism does that organism have? a. Oxidative only b. Oxidative...
