Distribution, abundance, and ecogenomics of the Palauibacterales, a new cosmopolitan thiamine-producing order within the Gemmatimonadota phylum

Key Points

• Palauibacterales are distributed globally and produce thiamine, a vital nutrient for many organisms.
• The study reveals a significant abundance of these microbes in diverse environments, indicating their ecological role.
• Ecogenomic analysis was employed to map the genetic traits linked to thiamine production within Palauibacterales.
• The findings may enhance understanding of nutrient cycling in ecosystems and the role of microbes in health.
