Question: What are the major advantages of radioisotopic methods in the
What are the major advantages of radioisotopic methods in the study of microbial ecology? What type of controls (discuss at least two) would you include in a radioisotopic experiment to show 14CO2 incorporation by phototrophic bacteria or to show 35SO42− reduction by sulfate-reducing bacteria?
Relevant QuestionsHow might you combine SIP and NanoSIMS to identify novel methane-consuming cells in a natural community? Compare and contrast the use of FISH and phylochips for enumerating microbial cells in natural environments. What advantages and limitations do each of these methods have? Design a SIP experiment that would allow you to determine which organisms in a lake water sample were capable of oxidizing the hydrocarbon hexane (C6H14). Assume that four different species could do this. How would you ...The surface of a rock in a flowing stream will often contain a biofilm. What advantages could be conferred on bacteria growing in a biofilm compared with growth within the flowing stream? Why are most iron-oxidizing chemolithotrophs obligate aerobes and why are the better-studied iron oxidizers acidophilic?
