Fig. 4: The NOSC of removed DOM was correlated with BR and BGE.

From: Oxidation state of bioavailable dissolved organic matter influences bacterioplankton respiration and growth efficiency

Fig. 4

When heterotrophic cells were using more reduced DOM, their rate of respiration was slower, but their growth efficiency was higher. a NOSC was positively correlated with oxygen removal rates (R = 0.66, p = 0.0099, n = 13), and b inversely correlated with bacterioplankton growth efficiencies (BGEs; R = −0.67, p = 0.0004, n = 13). Noted on the top of the x-axis are predicted Gibbs free energies from LaRowe and van Cappellen (2011)29. The solid black best-fit line represents the weighted model II linear fit, and the dotted lines represent 95% confidence intervals. The error bars represent standard deviations.
