Figure 5: Physiological response of GX additions (TEP proxy) on N2 fixation.

From: Contribution of mono and polysaccharides to heterotrophic N2 fixation at the eastern Mediterranean coastline

Figure 5

Changes in N2 fixation (A), the proportion of the nifH expressing phototrophic and heterotrophic diazotrophs detected in the recovered cDNA (B), β-glucosidase activity rates (C) and bacterial carbon demand (D) following GX addition. Bottles were incubated for 48 h under dark + DCMU conditions. The asterisks above the columns represent significant differences (one-way ANOVA and a Fisher LSD means comparison test, P < 0.05) for mean values between additions.
