Fig. 4: DMSO incubation experiments with saltmarsh sediment samples from Spiekeroog (Pio and Edge, July 2019) and Stiffkey (Pool, July 2021).

A DMS (blue) and CH4 (black) production in incubation experiments. Sampling points for molecular analyses are marked with colored bars, with T0 at the beginning of the experiment (blue), T1 after peak DMS concentrations (red, only Stiffkey), and T2 (11d Spiekeroog, 13.5d Stiffkey) at the ends of the experiments designated by plateau CH4 concentrations and complete DMS removal (green). B Mean relative 16S rRNA gene abundances of all three experiments (Pio, Edge, Pool) of statistically significantly increased ASVs due to treatment (n = 3, deseq2, p ≤ 0.05, log2 fold change ≥ 0.5). Displayed ASVs had a relative abundance of >1% in at least one sample, while the remaining are grouped into “Others”.
