Diversity of Haloquadratum and other haloarchaea in three, geographically distant, Australian saltern crystallizer ponds [PDF]

, 2009
Haloquadratum walsbyi is frequently a dominant member of the microbial communities in hypersaline waters. 16S rRNA gene sequences indicate that divergence within this species is very low but relatively few sites have been examined, particularly in the ...

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.

Identification of an Amylomaltase from the Halophilic Archaeon Haloquadratum walsbyi by Functional Metagenomics: Structural and Functional Insights. [PDF]

Life (Basel), 2022
Amylomaltases are prokaryotic 4-α-glucanotransferases of the GH77 family. Thanks to the ability to modify starch, they constitute a group of enzymes of great interest for biotechnological applications.

Cyclic nucleotides in archaea: Cyclic di‐AMP in the archaeon Haloferax volcanii and its putative role

MicrobiologyOpen, Volume 8, Issue 9, September 2019., 2019
Cyclic di‐adenylate monophosphate (c‐di‐AMP) is an essential second messenger in bacteria, where it was demonstrated to have a central function in cellular osmoregulation. For archaea, currently little information on second messengers is available. This study proves that c‐di‐AMP is present in vivo in the archaeon Haloferax volcanii and demonstrates ...

An Acidic Exopolysaccharide from Haloarcula hispanica ATCC33960 and Two Genes Responsible for Its Synthesis

Archaea, Volume 2017, Issue 1, 2017., 2017
A 1.1 × 106 Da acidic exopolysaccharide (EPS) was purified from an extremely halophilic archaeon Haloarcula hispanica ATCC33960 with a production of 30 mg L−1 when grown in AS‐168 medium, which mainly composed of mannose and galactose with a small amount of glucose in a molar ratio of 55.9 : 43.2 : 0.9.

Unusually High Archaeal Diversity in a Crystallizer Pond, Pomorie Salterns, Bulgaria, Revealed by Phylogenetic Analysis

Archaea, Volume 2016, Issue 1, 2016., 2016
Recent studies on archaeal diversity in few salterns have revealed heterogeneity between sites and unique structures of separate places that hinder drawing of generalized conclusions. Investigations on the archaeal community composition in P18, the biggest crystallizer pond in Pomorie salterns (PS) (34% salinity), demonstrated unusually high number of ...
