This research focused on investigating the large quantity of dissolved inorganic carbon production observed in anoxic permeable sediments, that could not be attributed to known heterotrophic processes. Through the use of flow through reactor experiments, metabolomic and porewater analyses were used to identify the process responsible. Large quantities of dissolved hydrogen and extensive lipid accumulation indicated fermentation was a major process under such conditions. Antibiotic flow through reactor treatments were used to confirm the minimal contribution by bacteria, indicating eukaryotic microalgae are likely employing dark fermentation to survive dark anoxic sediments.
