The abstract is read at the publisher; the summary is JClub's.
Lake-associated Kapaibacteriales isolates show widespread, summer-enriched, compact genomes, while groundwater isolates are geographically restricted with larger genomes enriched for regulation and mobile elements.
- Why it matters: Habitat-driven genomic diversification can obscure whether conserved metabolism persists, limiting cultivation of abundant aquatic microbes and understanding of their ecological roles.
- What they did: The study cultivated 29 axenic isolates from lakes and groundwater across three families and nine novel species, then combined global metagenomic profiling with comparative genomics.
- The result: Despite contrasting genome architectures, both lake and groundwater populations share predicted biosynthetic deficiencies for multiple amino acids, vitamins, and respiratory cofactors, implying persistent metabolic dependencies that can guide cultivation.
