Fig. 1From: Methane oxidation and methane driven redox process during sequential reduction of a flooded soil ecosystemRedox metabolism during sequential reduction processes in slurry incubated under aerobic (top) and anaerobic (bottom) conditions. NO3 − (black square), Fe2+ (black circle), SO4 2− (black up-pointing triangle) and CH4 (black diamond suit) were estimated at regular intervals from the incubated slurry samples to determine the time course of soil reduction process. Each data point represents the mean ± SD of triplicate slurry samplesBack to article page
