Design an experiment for measuring the activity of sulfur-oxidizing bacteria in soil. If only certain species of the sulfur oxidizers present were metabolically active, how could you tell this? How would you prove that your activity measurement was due to biological activity?
Answer to relevant QuestionsYou wish to know whether Archaea exist in a lake water sample but are unsuccessful in culturing any. Using techniques described in this chapter, how could you determine whether Archaea existed in the sample, and if they did, ...Many pelagic prokaryotes can use light energy but are not considered “phototrophs” in the same sense as cyanobacteria or purple bacteria. Explain. Imagine a sewage plant that is releasing sewage containing high levels of ammonia and phosphate and very low levels of organic carbon. Which types of microbial blooms might be triggered by this sewage? How would the graphs ...In what ways are Ca and Si cycling in ocean waters similar, and in what ways do they differ? How do the calcium and silica cycles couple to the carbon cycle? What physical and chemical conditions are necessary for the rapid microbial degradation of oil in aquatic environments? Design an experiment that would allow you to test which conditions optimized the oil oxidation process.
