Article Synopsis

* Advanced techniques like genome analysis and optical tweezers were used to isolate and study these microorganisms, revealing their rapid assimilation of C-starch in sediments.
* The study proposes a taxonomic reclassification of the Fervidibacteria, highlighting their important role in polysaccharide degradation within a newly defined class of the Armatimonadota phylum.

The aerobic hyperthermophile catabolizes diverse polysaccharides and is the only cultivated member of the class within the phylum . It encodes 117 putative glycoside hydrolases (GHs), including two from GH family 50 (GH50). In this study, we expressed, purified, and functionally characterized one of these GH50 enzymes, Fsa16295Glu.
