Question

What is the main difference between proteobacteria and non-proteobacteria?

Answer 1

Proteobacteria: They are a broad group of bacteria that include all Gram-Negative bacteria among which a very few species of proteobacteria can perform photosynthesis to produce energy.

Non-proteobacteria: They are a broad group of bacteria that include both Gram-positive and Gram-Negative bacteria. All species in this group can perform photosynthesis and produce energy.
