The underlying molecular mechanism governing this phenomenon is not fully understood. Here, we investigate the role of Fe(III) in C-GHG production using a multiomics approach through a lab-based microcosm experiment on tropical peat collected from three different depths of an Acacia plantation site. Fe(III) amendment leads to severalfold higher production of CO2 and CH4 than unamended setups. Moreover, the gas profile correlates with depletion of carbohydrate compounds in the upper and middle depths, indicating microbial preference for readily fermentable substrates, aligning with increased CO2 production as well as the enrichment of fermentative microbes and genes associated with complex organic carbon degradation. Our study highlights the underestimated role of Fe(III) in carbon transformation and its potential to exacerbate climate change impacts on tropical peatlands.<\/jats:p>","DOI":"10.1093\/ismeco\/ycag139","type":"journal-article","created":{"date-parts":[[2026,6,4]],"date-time":"2026-06-04T11:43:03Z","timestamp":1780573383000},"source":"Crossref","is-referenced-by-count":0,"title":["Iron stimulates greenhouse gas production in Southeast Asian peatlands"],"prefix":"10.1093","volume":"6","author":[{"given":"Andrew Elohim","family":"Laloo","sequence":"first","affiliation":[{"name":"National University of Singapore Environmental Research Institute, National University of Singapore , Singapore 117411 ,","place":["Singapore"]},{"name":"Singapore Centre for Environmental Life Sciences Engineering, ,","place":["Singapore 637551, Singapore"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhishek","family":"Gupta","sequence":"additional","affiliation":[{"name":"National University of Singapore Environmental Research Institute, National University of Singapore , Singapore 117411 ,","place":["Singapore"]},{"name":"Singapore Centre for Environmental Life Sciences Engineering, ,","place":["Singapore 637551, Singapore"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeria","family":"Verrone","sequence":"additional","affiliation":[{"name":"National University of Singapore Environmental Research Institute, National University of Singapore , Singapore 117411 ,","place":["Singapore"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rama Kant","family":"Dubey","sequence":"additional","affiliation":[{"name":"National University of Singapore Environmental Research Institute, National University of Singapore , Singapore 117411 ,","place":["Singapore"]},{"name":"Department of Biological Sciences, National University of Singapore , Singapore 117558 ,","place":["Singapore"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Taillardat","sequence":"additional","affiliation":[{"name":"National University of Singapore Environmental Research Institute, National University of Singapore , Singapore 117411 ,","place":["Singapore"]},{"name":"Asian School of the Environment , Nanyang Technological University, Singapore 639798 ,","place":["Singapore"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajpirathap","family":"Nagasaijanani","sequence":"additional","affiliation":[{"name":"Singapore Centre for Environmental Life Sciences Engineering, ,","place":["Singapore 637551, Singapore"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad Iman Faisal","family":"Harahap","sequence":"additional","affiliation":[{"name":"Asia Pacific Resources International Ltd.
