Which of the following best distinguishes deltaproteobacteria from epsilonproteobacteria?
A) Deltaproteobacteria are most commonly found at anoxic-oxic interfaces while epsilonbacteria are most commonly found in anoxic environements.
B) Many epsilonbacteria oxidize sulfur compounds, which could be produced by a sulfur-reducing deltaproteobacterium.
C) A sulfate-reducing epsilonbacterium produces sulfite, which a deltaproteobacterium reduces further to hydrogen sulfide.
D) An epsilonbacterium reduces sulfur compounds whereas all deltaproteobacteria oxidize sulfur compounds.

Question

Quizplus · Accepted Answer

Many epsilonbacteria are known for their ability to oxidize sulfur compounds, a characteristic that can be linked to the sulfur cycle where sulfur-reducing deltaproteobacteria produce compounds that epsilonbacteria can then utilize. This interconnection highlights a significant ecological relationship between these two groups, distinguishing them based on their roles in sulfur metabolism.
