The National Science Foundation (NSF) is offering a federal grant opportunity titled "Building Synthetic Microbial Communities for Biology, Mitigating Climate Change, Sustainability and Biotechnology." This initiative aims to support projects that utilize model synthetic microbial communities to enhance understanding of natural community dynamics and develop synthetic communities with novel capabilities, addressing fundamental biological principles across various scales. The program is significant for advancing knowledge in microbial systems, which play a crucial role in ecosystems, health, and the economy, with an estimated total funding of $10 million available for approximately 12 awards. Proposals are due by February 3, 2025, and interested applicants can reach out to NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
