Nanohaloarchaea as beneficiaries of xylan degradation by haloarchaea

Microbial Biotechnology, Volume 16, Issue 9, Page 1803-1822, September 2023., 2023
Using samples of natural evaporitic brines and anthropogenic solar salterns, we describe genome‐inferred trophic relations in two extremely halophilic xylan‐degrading three‐member consortia. We succeeded in genome assembly and closure for all members of both xylan‐degrading cultures and elucidated the respective food chains within these consortia.
