Bioluminescent Microorganisms are Found in Which of the Following Groups

Question

Bioluminescent microorganisms are found in which of the following groups?
A) Firmicutes
B) Thaumarchaeota
C) Gammaproteobacteria
D) Verrucomicrobia

Accepted Answer

Bioluminescent microorganisms are primarily found in the Gammaproteobacteria group, which includes species such as Vibrio fischeri and Photobacterium phosphoreum. While there are some bioluminescent species found in other bacterial groups such as Firmicutes, the majority are in the Gammaproteobacteria. Thaumarchaeota and Verrucomicrobia are both groups of archaea and bacteria, respectively, but bioluminescent species are not typically found in these groups.
