Which gammaproteobacteria genera include species that oxidize H₂S to S⁰?
A) Escherichia and Enterobacter
B) Chromatium and Beggiatoa
C) Klebsiella and Shigella
D) Proteus and Erwinia
E) Rhodobacter and Nitrosomonas

Question

Quizplus · Accepted Answer

Chromatium and Beggiatoa are both genera of gammaproteobacteria that include species capable of oxidizing H₂S to S⁰. This process is known as sulfur oxidation and is an important aspect of many sulfur-reducing bacteria. Other options listed either do not include genera that can perform this process (A, C, D, E) or are not related to H₂S oxidation (E).
