acI Actinobacteria Assemble a Functional Actinorhodopsin with Natively Synthesized Retinal

| asm.org
ABSTRACT Freshwater lakes harbor complex microbial communities, but these ecosystems are often dominated by acI Actinobacteria. Members of this cosmopolitan lineage are proposed to bolster heterotrophic growth using phototrophy because their genomes encode actino-opsins (actR). This model has been difficult to validate experimentally because acI Actinobacteria are not consistently culturable.

Stability of Ferrihydrite-Humic Acid Coprecipitates under Iron-Reducing Conditions

|
By Jacqueline Mejia, Shaomei He, Yu Yang, Matthew Ginder-Vogel
| American Chemical Society
Recent studies have suggested the potential for release of iron (hydr)oxide-bound organic carbon (OC) during dissimilatory iron oxide reduction (DIR). However, the stability of iron (hydr)oxide-bound OC in the presence of a natural microbial consortium capable of driving both OC metabolism and DIR has not been resolved.

Dual Role of Humic Substances As Electron Donor and Shuttle for Dissimilatory Iron Reduction

|
By Noah Stern, Yu Yang, Jacqueline Mejia, Shaomei He
| American Chemical Society
Dissimilatory iron-reducing bacteria (DIRB) are known to use humic substances (HS) as electron shuttles for dissimilatory iron reduction (DIR) by transferring electrons to HS-quinone moieties, which in turn rapidly reduce Fe(III) oxides. However, the potential for HS to serve as a source of organic carbon (OC) that can donate electrons for DIR is unknown.
