Abstract Background Mangrove ecosystems are considered as hot spots of biogeochemical cycling, yet the diversity, function and coupling mechanism microbially driven cycling along sediment depth mangrove wetlands remain elusive. Here we investigated vertical profile methane (CH 4 ), nitrogen (N) sulphur (S) genes/pathways their potential mechanisms using metagenome sequencing approaches. Results Our results showed that metabolic pathways involved in CH , N S were mainly shaped by pH acid volatile sulphide (AVS) a depth, AVS was critical electron donor impacting oxidation denitrification. Gene families denitrification significantly ( P < 0.05) decreased could be coupled S-driven denitrifiers, such Burkholderiaceae Sulfurifustis surface (0–15 cm). Interestingly, all denitrifier metagenome-assembled genomes (MAGs) appeared to incomplete denitrifiers with nitrate/nitrite/nitric oxide reductases (Nar/Nir/Nor) but without nitrous reductase (Nos), suggesting sulphide-utilizing groups might an important contributor 2 O production sediment. methanogenesis reduction increased depth. Based on both network MAG analyses, sulphate-reducing bacteria (SRB) develop syntrophic relationships anaerobic oxidizers (ANMEs) direct transfer or zero-valent sulphur, which would pull forward co-existence methanogens SRB middle deep layer sediments. Conclusions In addition offering perspective distribution genes/pathways, this study emphasizes role emissions various possible ANMEs The exploration provides novel insights into future synthetic microbial community construction analysis. This also has implications for predicting ecosystem functions within context environmental global change.

Constructed wetlands (CWs) are artificial systems that use natural processes to treat wastewater containing organic pollutants. This approach has been widely applied in both developing and developed countries worldwide, providing a cost-effective method for industrial treatment the improvement of environmental water quality. However, due large carbon inputs, CWs is produced varying amounts CH
