Question

Quizplus · Accepted Answer

Proteobacteria is the phylum that harbors the most functional diversity observed and also has the most cultured representatives. This phylum includes diverse groups of bacteria such as Alpha-, Beta-, Gamma-, Delta-, and Epsilonproteobacteria, which play important roles in various ecological niches and biogeochemical cycles. Moreover, many of the well-characterized model organisms and medically important bacteria belong to this phylum (e.g., Escherichia coli, Salmonella, Helicobacter pylori, Vibrio cholerae, Pseudomonas aeruginosa, etc.), which has facilitated extensive research and cultivation.
