Abstract Accumulating evidences are challenging the paradigm that methane in surface water primarily stems from anaerobic transformation of organic matters. Yet, contribution oxygenic photosynthetic bacteria, a dominant species water, to production remains unclear. Here we show methanogenesis triggered by interaction between bacteria and methanogenic archaea. By introducing cyanobacterium Synechocystis PCC6803 archaea Methanosarcina barkeri with redox cycling iron, CH 4 was induced coculture biofilms through both syntrophic (under anoxic conditions darkness) abiotic oxic illumination) during periodic dark-light cycles. We have further demonstrated other model various phyla, conjunction different exhibiting diverse energy conservation modes, as well common Fe-species. These findings revealed an unexpected link photosynthesis would advance our understanding bacteria’s ecological role global cycle. Such light-driven may be widely present nature.
