A chemolithoautotroph is respiring using only iron (Fe3+) and nitrite (NO2-). This bacterium does not consume organic molecules.
From where does this organism obtain its carbon?
What is one difference between fermentation and anaerobic respiration? Since neither requires oxygen, why would a microbe select one of these versus the other? Name a specific microbe which uses fermentation and a specific microbe which uses anaerobic respiration.
If the result of an unknown bacteria is “poor growth” and “red growth,” can this result be interpreted as “organism does not ferment mannitol?” Explain why or why not.
If the result of an unknown bacteria is “good growth” and “yellow growth,” is the unknown bacteria more likely Staphylococcus aureus or Staphylococcus epidermidis?
