Textbook Question
Chapter 19, Problem 3AQ
Design an experiment to solve the following problem: Determine the rate of methanogenesis (CO2 + 4 H2 → CH4 + 2 H2O) in anoxic lake sediments and whether or not it is H2-limited. Also, determine the morphology of the dominant methanogen (recall that these are Archaea, Section 17.2). Finally, calculate what percentage the dominant methanogen is of the total archaeal and total prokaryotic populations in the sediments. Remember to specify necessary controls.

Explain two ways in which archaea metabolize inorganiccompounds in extreme environments.
discuss at least five different examples of extremophiles on Earth and discuss how they thrive in their special environments (or, each person can choose one extremophile to research and share with the rest of the group).
Extrapolate these extreme survival abilities to the kinds of life that might be able to survive in the very different environments throughout our Solar System? Do you think that watery places like Europa or Enceladus would be a better environment to search for life as opposed to somewhere like the clouds of Venus? Why or why not? For more information on possible life in Venus' atmosphere,
Discuss the possibility of life on Mars. In reference to extremophiles.
Defend or refute this statement: The upper-temperature limit to life is unrelated to the stability of proteins or nucleic acids.
How influential is microbial activity on the geological processes of mineral formation and deposition compared to biological processes? (argue both sides of this one).
What challenges and advantages do you see with the use of extremeophiles in industrial or bioremediation applications?

- In a population of cyanobacteria (Chlorogloeopsis fritschii) in a hot spring in Iceland, some of the bacteria can produce chlorophyll f, while some C. fritschii produce only other types of chlorophylls. Chlorophyll f absorbs light outside of the visible light spectrum, namely near infrared light, allowing the bacteria to absorb light that has not been absorbed or reflected by the water or other organisms. The ability to produce chlorophyll f is heritable, and the bacteria with chlorophyll f can live in low-light environments, such as underneath other organisms, or near the bottom of the light-penetrating zone of the spring. What is the adaptation in this population of C. fritschii living in low-light environments? (Choose one.) a) the ability to produce chlorophyll f b) the ability to produce any type of chlorophyll c) the ability to tolerate the high temperatures of the hot spring d) the ability to survive and reproducearrow_forwardDraw a key to differentiate the following bacteria: Cyanobacteria, Cytophaga, Desulfovibrio, Frankia, Hyphomicrobium, Methanogens, Myxobacteria, Nitrobacter, purple bacteria, Sphaerotilus, and Sulfolobus.

Explain.arrow_forwardFor you master's degree you have joined a lab that seeks to identify and investigate novel organisms that can survive in rare and challenging environments. You will be working with a research associate in the lab to continue characterizing cultured cells (e.g – cells grown in a dish) isolated cells from a complex multicellular eukaryotic organism Onlinus extremus. Preliminary evidence from research in the laboratory has shown that O.Extremus is capable of both fermentation and cellular respiration. While they can survive on a wide variety of questionably food- like fuel sources, like most other eukaryotic organisms', glucose is its preferred fuel source. Practice question 1 and begin expanding the culture (increasing the # of cells) so that you may later conduct experiments on them. You take two aliquots, each with an equal number of cells, and place them in two different culture vessels, one is a sealed airtight flask (culture 1) and the other is an open topped culture dish (culture…arrow_forward
