a. NMDS ordination plot, based on Bray-Curtis distance matrixes of log (X + 1)-transformed typifying relative abundance of predicted KO related to the S-, As-, N-, CH4-related biogeochemical cycles in thermal waters and groundwaters. The stress value (i.e., < 0.2) suggests for an accurate representation of the dissimilarity among samples. b. Correspondence analysis plot based on groundwaters data. c. Correspondence analysis plot based on thermal waters data. a, S-related compounds oxidation; b, As(V) reduction; c, As transcription factors; d, S-related compounds reduction; e, As(III) oxidation; f, As resistance; g, As transporters; h, nitrogen fixation; i, methanogenesis; j, denitrification; k, nitrification; l, methane oxidation; m, assimilatory nitrate reduction; n, dissimilatory nitrate reduction; o, complete nitrification (comammox).
