The National Science Foundation (NSF) awarded a $590,658 project grant to Arizona State University (ASU) under the Geosciences program (CFDA 47.050) to conduct research on the mechanisms of metal sulfide-enabled growth of anoxygenic photosynthetic bacteria. The research team will use transcriptomic sequencing, electron microscopy, and various chemical analysis tools to examine if all transition metal sulfide phases can enable the autotrophic growth of purple sulfur bacteria as sole sulfur and electron donors, and to elucidate the molecular mechanisms involved in these bacteria-mineral interactions. This research may have implications for understanding ancient and modern metal-sulfur biogeochemical cycles, bacterial extracellular electron transfer, and the potential synergy between nanoparticle photochemistry and microbial energy demand. The award also includes outreach activities, such as creating animation videos and an open-access tutorial, to disseminate the research findings and train a diverse group of students in STEM disciplines.
