This federal Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports collaborative research to investigate the ecological significance and impact of viral infections on sulfate-reducing microbial communities. The total award amount is $434,023, with a project period from September 1, 2025 to August 31, 2028. The research aims to understand the relationships between viruses and sulfate-reducing bacteria, and how these interactions contribute to carbon cycling. The project uses a multidisciplinary approach, including environmental observations, process-oriented biogeochemical incubations, and modeling, to determine the impact of viruses on sediment metabolism and quantify their influence on microbial sulfate reduction rates. Additionally, the project supports STEM workforce development through experiential learning activities at K-12, undergraduate, and graduate levels, highlighting research on the Gulf Coast region and the importance of microorganisms in coastal ecosystems. The project is led by the Louisiana Board of Regents, the state agency responsible for coordinating public higher education in Louisiana.
