From: Citrulline deiminase pathway provides ATP and boosts growth of Clostridium carboxidivorans P7
Under heterotrophic conditions, the effects of citrulline on the fermentation of C. carboxidivorans P7. C. carboxidivorans P7 was cultivated in MM520 medium (A) and MM520-0.6 Cit medium (B). C Doubling time, D Specific growth rate, (E) The concentration of ATP. F The yield of ethanol, butanol, acetate, and butyrate in heterotrophic conditions. *P < 0.05. **P < 0.01
