Figure 7From: Energy metabolism of Heliobacterium modesticaldum during phototrophic and chemotrophic growthCell growth with or without nitrogen fixation in pyruvate-grown cultures during phototrophic and chemotrophic growth. The cells were grown in the minimal medium with pyruvate as sole carbon source and NH4+ or N2/H2 = 98/2 as the nitrogen source.Back to article page
