Fig. 3: Phylogenetic tree, relative abundance, and gene content of metagenome assembled genomes (MAGs) identified as the facultative sulfide-oxidizing heterotrophic denitrifiers (F-SOHDs).

a Phylogenetic placement of 63 representative MAGs assembled in the present study. Genomes from the phylum Planctomycetota were selected as the outgroup. Five complete genomes retrieved from public databases that are closely related to F-SOHDs and have similar inferred functions were employed as reference genomes. b Relative abundances of assembled MAGs in natural sediments, short-term isotope-incubated sediments, heavy DNA fractions of DNA-SIP experiments, and enrichment cultures. ENRC represents the metagenome of ENR_C4 enrichment. c Presence/absence of genes involved in carbon, nitrogen, and sulfur metabolism. Solid/hollow circles indicate the presence/absence of target pathways. Gray circles within the carbon fixation column indicates that DNA-SIP experiments and abundance shifts confirm the inability to fix carbon despite the presence of rbcL gene in corresponding genome.
