The extreme halophilic archaeon Haloferax volcanii reduced Fe(III) to conserve energy from extracellular electron transfer

Journal of Bacteriology
Iron availability affects oceanic primary productivity and the strength of the biological carbon pump. However, the mechanism of iron solubility in hypersaline environments is poorly understood.

DNA replication origins in Haloferax volcanii [PDF]

, 2009
DNA replication is fundamental to the proliferation of life. Sites of DNA replication initiation are called replication origins. Bacteria replicate from a single origin whereas eukaryotes utilise multiple origins for each chromosome. The archaeal domain includes species which replicate using multiple origins of replication in addition to those which ...

Ultrasound Imaging Properties of Heterologously Synthesized Gas Vesicles from Halophilic Archaeon

Nanomaterials
Biosynthetic gas vesicles (GVs), as novel nanoscale ultrasound contrast agents, exhibit unique potential in biomedical ultrasound imaging. For example, they are expected to have better tissue penetration through the tumor vasculature for detecting tumor ...

CsmR controls both, motility and cell shape, in Haloferax volcanii.

PLoS Genetics
Archaea rely on motility and morphological plasticity to navigate their environments, yet the transcriptional regulation of these processes remains poorly understood.

A previously undescribed archaeal virus suppresses host immunity

EMBO Reports
Extremophilic archaea can have chronic viral infections that are well-tolerated by the hosts and may potentially protect against more lethal infections.

DPANN symbiont of Haloferax volcanii accelerates xylan degradation by the non-host haloarchaeon Halorhabdus sp.

iScience
Summary: This study examines a natural consortium of halophilic archaea, comprising xylan-degrading Halorhabdus sp. SVX81, consortium cohabitant Haloferax volcanii SVX82 (formerly H. lucentense SVX82), and its DPANN ectosymbiont Ca.

A systematic analysis of affinity tags in the haloarchaeal expression system, Haloferax volcanii for protein purification

Frontiers in Microbiology
Extremophilic proteins are valuable in various fields, but their expression can be challenging in traditional hosts like Escherichia coli due to misfolding and aggregation. Haloferax volcanii (H.

Perchlorate supported anaerobic growth in Haloferax volcanii reveals a novel metabolic capability with implications for biosignature degradation

Scientific Reports
Haloferax volcanii (H. volcanii) is a facultatively anaerobic model halophilic archaeon capable of anaerobic growth using nitrate, chlorate, fumarate, trimethylamine N-oxide (TMAO), and dimethyl sulfoxide (DMSO) as alternative electron acceptors.
