Fig. 2: Sulfate concentrations and pH in the rice-vegetated pots.
From: Cable bacteria reduce methane emissions from rice-vegetated soils

a Sulfate concentrations in the porewater of pots with cable bacteria (top) and in pots without cable bacteria (bottom). b Depth profiles of pH measured with microelectrodes in pots with cable bacteria (circles) and without cable bacteria (triangles). Data are presented as mean ±  standard error of the mean (n = 4).
