Lipids of the ultra‐thin square halophilic archaeon Haloquadratum walsbyi [PDF]

Archaea, 2008
The lipid composition of the extremely halophilic archaeon Haloquadratum walsbyi was investigated by thin‐layer chromatography and electrospray ionization‐mass spectrometry. The analysis of neutral lipids showed the presence of vitamin MK‐8, squalene, carotene, bacterioruberin and several retinal isomers.

Evaluating the potential for Haloarchaea to serve as ice nucleating particles [PDF]

Biogeosciences, 2021
Aerosols play a crucial role in cloud formation. Biologically derived materials from bacteria, fungi, pollen, lichen, viruses, algae, and diatoms can serve as ice nucleating particles (INPs), some of which initiate glaciation in clouds at relatively warm

Production of Poly(3‐Hydroxybutyrate) by Haloarcula, Halorubrum, and Natrinema Haloarchaeal Genera Using Starch as a Carbon Source

Archaea, Volume 2021, Issue 1, 2021., 2021
Microbial production of bioplastics, derived from poly(3‐hydroxybutyrate) (PHB), have provided a promising alternative towards plastic pollution. Compared to other extremophiles, halophilic archaea are considered as cell factories for PHB production by using renewable, inexpensive carbon sources, thus decreasing the fermentation cost.

Diversity of the cell-wall associated genomic island of the archaeon Haloquadratum walsbyi [PDF]

BMC Genomics, 2015
Haloquadratum walsbyi represents up to 80% of cells in NaCl-saturated brines worldwide, but is notoriously difficult to maintain under laboratory conditions. In order to establish the extent of genetic diversity in a natural population of this microbe, we screened a H. walsbyi enriched metagenomic fosmid library and recovered seven novel version of its

Substrate specificities of inteins investigated by QuickDrop‐cassette mutagenesis

FEBS Letters, Volume 594, Issue 20, Page 3338-3355, October 2020., 2020
Inteins catalyze self‐excision from host precursor proteins while concomitantly ligating the flanking substrates (exteins) with a peptide bond. Noncatalytic extein residues near the splice junctions, such as the residues at the −1 and +2 positions, often strongly influence the protein‐splicing efficiency. The substrate specificities of inteins have not

Visualizing the invisible: class excursions to ignite children’s enthusiasm for microbes

Microbial Biotechnology, Volume 13, Issue 4, Page 844-887, July 2020., 2020
The ubiquity of microbes, their manifold activities and pervasive influence on the health of all life, local environments and the planet, necessitate an understanding of relevant microbial processes for informed, evidence‐based decision‐making at all levels of society – i.e. Microbiology Literacy.

Whole‐genome comparison between the type strain of Halobacterium salinarum (DSM 3754T) and the laboratory strains R1 and NRC‐1

MicrobiologyOpen, Volume 9, Issue 2, February 2020., 2020
The genome of the Halobacterium salinarum type strain (91‐R6, DSM 3754) was compared at the DNA and protein levels to the genomes of two well‐studied laboratory strains, NRC‐1 and R1. The chromosomes and portions of the plasmids were very closely related. However, distinct homologs for proteins involved in motility and N‐glycosylation were encountered.

Comparison of prokaryotic community structure from Mediterranean and Atlantic saltern concentrator ponds by a metagenomic approach

Frontiers in Microbiology, 2014
We analyzed the prokaryotic community structure of a saltern pond with 21 % total salts located in Isla Cristina, Huelva, Southwest Spain, close to the Atlantic ocean coast.

Pyruvate: A key Nutrient in Hypersaline Environments?

Microorganisms, 2015
Some of the most commonly occurring but difficult to isolate halophilic prokaryotes, Archaea as well as Bacteria, require or prefer pyruvate as carbon and energy source.

Structure of a retinal chromophore of dark-adapted middle rhodopsin as studied by solid-state nuclear magnetic resonance spectroscopy

Biophysics and Physicobiology, 2021
Middle rhodopsin (MR) found from the archaeon Haloquadratum walsbyi is evolutionarily located between two different types of rhodopsins, bacteriorhodopsin (BR) and sensory rhodopsin II (SRII). Some isomers of the chromophore retinal and the photochemical
