Methylobacterium Species are Methylotrophs, Which Means That They

Question

Methylobacterium species are methylotrophs, which means that they
A) can oxidize reduced single-carbon compounds.
B) exclusively feed on methane.
C) generate methane as a product of fermentation.
D) perform bacteriochlorophyll-based photosynthesis.
E) are classified as lithotrophs.

Accepted Answer

Methylobacterium species are methylotrophs, which means they can oxidize reduced single-carbon compounds such as methanol or formaldehyde.

Answer: B, C, D, and E are incorrect. 
 Methylobacterium species are not exclusively fed on methane (B), nor do they generate methane as a byproduct of fermentation (C). They do not perform bacteriochlorophyll-based photosynthesis (D), and they are not classified as lithotrophs (E).
