The Effects of Temperature and Growth Phase on the Lipidomes of Sulfolobus islandicus and Sulfolobus tokodaii [PDF]

Life, 2015
The functionality of the plasma membrane is essential for all organisms. Adaption to high growth temperatures imposes challenges and Bacteria, Eukarya, and Archaea have developed several mechanisms to cope with these.

Sulfolobus – A Potential Key Organism in Future Biotechnology

Frontiers in Microbiology, 2017
Extremophilic organisms represent a potentially valuable resource for the development of novel bioprocesses. They can act as a source for stable enzymes and unique biomaterials.

Early Response of Sulfolobus acidocaldarius to Nutrient Limitation [PDF]

Frontiers in Microbiology, 2019
In natural environments microorganisms encounter extreme changes in temperature, pH, osmolarities and nutrient availability. The stress response of many bacterial species has been described in detail, however, knowledge in Archaea is limited.

The influence of the specific growth rate on the lipid composition of Sulfolobus acidocaldarius

Extremophiles, 2020
Archaeal lipids are constituted of two isoprenoid chains connected via ether bonds to glycerol in the sn-2, 3 position. Due to these unique properties archaeal lipids are significantly more stable against high temperature, low pH, oxidation and enzymatic

A TetR-family transcription factor regulates fatty acid metabolism in the archaeal model organism Sulfolobus acidocaldarius

Nature Communications, 2019
Certain archaea appear to metabolize fatty acids, but the regulation of these pathways is unclear. Here, Wang et al. provide genetic, functional and structural evidence supporting that a TetR-family transcriptional regulator is involved in regulation of ...

High-Temperature Live-Cell Imaging of Cytokinesis, Cell Motility, and Cell-Cell Interactions in the Thermoacidophilic Crenarchaeon Sulfolobus acidocaldarius

Frontiers in Microbiology, 2021
Significant technical challenges have limited the study of extremophile cell biology. Here we describe a system for imaging samples at 75°C using high numerical aperture, oil-immersion lenses.

The essential genome of the crenarchaeal model Sulfolobus islandicus

Nature Communications, 2018
Sulfolobus islandicus is a model organism within the TACK superphylum of the Archaea. Here, the authors perform a genome-wide analysis of essential genes in this organism, show that the proteinaceous S-layer is not essential, and explore potential stages

Genome sequencing of Sulfolobus sp. A20 from Costa Rica and comparative analyses of the putative pathways of carbon, nitrogen and sulfur metabolism in various Sulfolobus strains

Frontiers in Microbiology, 2016
The genome of Sulfolobus sp. A20 isolated from a hot spring in Costa Rica was sequenced. This circular genome of the strain is 2,688,317 bp in size and 34.8% in G+C content, and contains 2,591 open reading frames (ORFs). Strain A20 shares ~95.6% identity

Cell Structure Changes in the Hyperthermophilic Crenarchaeon Sulfolobus islandicus Lacking the S-Layer

mBio, 2019
Rediscovery of the ancient evolutionary relationship between archaea and eukaryotes has revitalized interest in archaeal cell biology. Key to the understanding of archaeal cells is the surface layer (S-layer), which is commonly found in Archaea but whose

DNA-Interacting Characteristics of the Archaeal Rudiviral Protein SIRV2_Gp1 [PDF]

Viruses, 2017
Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored.
