How can this CPR strain make its cell membrane? Many CPR (Ca. Patescibacteria) bacteria cannot make fatty acids. If CPR bacteria form cross-domain symbiosis with archaeal hosts, then can hosts provide fatty acids enough to build symbionts' cell membrane?

Important clarification: CPR bacteria ≠ Patescibacteria. When constructing trees without relying on RED scores, it becomes evident that CPR is not a single phylum, but rather comprises multiple distinct phyla.

Not that I'd want to overhype 16S, but I might suggest it in cases if the alternative is kraken+refseq 🤣
But we've made as far as "Only part of the CPR diversity can be captured by 16S" (holds true for other candidatus in my experience), which is an improvement!
