Metabolism and Life Cycle

C. nitrophenolicus is a strict aerobe and grows best with pNP as its sole carbon, electron and energy source. Although the favored food source was pNP, growth was also observed when food sources such as short chain fatty acids, salicylate and a range of alcohols such as phenols and 4-cholorphenols were present. All these served as electron donors for growth.

- When pNP was used as the only source of carbon and energy: Metabolism of pNP resulted in the release of nitrite

- When incubated with pNP and acetate: pNP was metabolized first and then acetate

- When grown solely on acetate: Both nitrite and nitrate served as oxygen sources where nitrate was quickly reduced to nitrite and therefore quickly accumulated in cultures during aerobic growth.
