Cell Surface Glycosylation Is Required for Efficient Mating of Haloferax volcanii

Frontiers in Microbiology, 2017
Halophilic archaea use a fusion-based mating system for lateral gene transfer across cells, yet the molecular mechanisms involved remain unknown. Previous work implied that cell fusion involves cell–cell recognition since fusion occurs more efficiently ...

Haloferax and the Haloferacaceae: Potential role in bioindustry

Biotechnology Advances
Members of the Haloferacaceae, a family of extremely halophilic archaea, exhibit unique physiological and genetic traits that make them promising candidates for biotechnological applications. These organisms thrive in hypersaline environments and tolerate a wide range of stresses, including high temperatures, UV radiation, and toxic metals.

Exploring the diversity of pyruvate:ferredoxin oxidoreductases

Protein Science, Volume 35, Issue 12, December 2026.
Abstract Pyruvate:ferredoxin oxidoreductases (PFORs) are key enzymes in the anaerobic metabolism of numerous diverse organisms. Their significance extends far beyond the oxidative decarboxylation of pyruvate, their canonical reaction. PFORs support diverse physiological roles, including fermentation and carbon assimilation, and have been integrated ...

Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery

Molecular Microbiology, Volume 126, Issue 4, Page 433-450, October 2026.
The Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.

Tunable Natural Deep Eutectic Solvents‐Driven Fractionation of Olive Pomace in an Integrated Biorefinery: Linking Lignin Structural Tailoring to Carbohydrate Valorization and Biopolymer Production

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Microwave‐conditioned olive pomace was fractionated with deep eutectic solvents (DESs) spanning acidic, neutral, alkaline, and chemo‐enzymatic regimes. The alkaline DES provided the best balance between delignification and carbohydrate preservation, yielding a fermentable glucose/xylose stream suitable for Haloferax mediterranei fermentation and poly(3‐

A Novel Polyphosphate‐Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii

Environmental Microbiology, Volume 28, Issue 7, July 2026.
A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

The FEBS Journal, Volume 293, Issue 14, Page 4397-4410, July 2026.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...
