Comparative Genome Analysis of Three Halobacillus Strains Isolated From Saline Environments Reveal Potential Salt Tolerance and Algicidal Mechanisms

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Following the previous complete genome analysis, this research provides the function of new Halobacillus species. Three strains were identified: Halobacillus shinanisalinarum sp. nov. SSTM10‐2T, Halobacillus salinarum sp. nov. SSBR10‐3T, and Halobacillus amylolyticus sp. nov. SSHM10‐5T.

Determination of the Residual Anthracene Concentration in Cultures of Haloalkalitolerant Actinomycetes by Excitation Fluorescence, Emission Fluorescence, and Synchronous Fluorescence: Comparative Study

Journal of Analytical Methods in Chemistry, Volume 2016, Issue 1, 2016., 2016
Polycyclic aromatic hydrocarbons (PAHs) are compounds that can be quantified by fluorescence due to their high quantum yield. Haloalkalitolerant bacteria tolerate wide concentration ranges of NaCl and pH. They are potentially useful in the PAHs bioremediation of saline environments.

Genomic features of lichen‐associated black fungi

IUBMB Life, Volume 77, Issue 1, January 2025.
Abstract Lichens are mutualistic associations consisting of a primary fungal host, and one to few primary phototrophic symbiont(s), usually a green alga and/or a cyanobacterium. They form complex thallus structures, which provide unique and stable habitats for many other microorganisms. Frequently isolated from lichens are the so‐called black fungi, or

Purification and Characterization of a Polyextremophilic α‐Amylase from an Obligate Halophilic Aspergillus penicillioides Isolate and Its Potential for Souse with Detergents

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
An extracellular α‐amylase from the obligate halophilic Aspergillus penicillioides TISTR3639 strain was produced and enriched to apparent homogeneity by ammonium sulfate precipitation and Sephadex G100 gel filtration column chromatography. The mass of the purified amylase was estimated to be 42 kDa by SDS‐PAGE.

Synthesis of salt-stable fluorescent nanoparticles (quantum dots) by polyextremophile halophilic bacteria [PDF]

Scientific Reports, 2019
AbstractHere we report the biological synthesis of CdS fluorescent nanoparticles (Quantum Dots, QDs) by polyextremophile halophilic bacteria isolated from Atacama Salt Flat (Chile), Uyuni Salt Flat (Bolivia) and the Dead Sea (Israel). In particular, a Halobacillus sp. DS2, a strain presenting high resistance to NaCl (3–22%), acidic pH (1–4) and cadmium

Characterization of Skoliomonas gen. nov., a haloalkaliphilic anaerobe related to barthelonids (Metamonada)

Journal of Eukaryotic Microbiology, Volume 71, Issue 6, November/December 2024.
Abstract Metamonads are a large and exclusively anaerobic group of protists. Additionally, they are one of the three clades proposed to ancestrally possess an “excavate” cell morphology, with a conspicuous ventral groove accompanied by a posterior flagellum with a vane.

Archaeal Communities in a Heterogeneous Hypersaline‐Alkaline Soil

Archaea, Volume 2015, Issue 1, 2015., 2015
In this study the archaeal communities in extreme saline‐alkaline soils of the former lake Texcoco, Mexico, with electrolytic conductivities (EC) ranging from 0.7 to 157.2 dS/m and pH from 8.5 to 10.5 were explored. Archaeal communities in the 0.7 dS/m pH 8.5 soil had the lowest alpha diversity values and were dominated by a limited number of ...

Life Beyond Earth: A Literature Review on the Possibility of Polyextremophilic Microbes on Mars [PDF]

, 2019
Extremophiles are organisms that can survive in adverse conditions. Over the last decades, interest in microorganisms with such abilities has been increasing, mostly because conclusions regarding extraterrestriallife might be drawn from studying their ...

Characterization of novel mevalonate kinases from the tardigrade Ramazzottius varieornatus and the psychrophilic archaeon Methanococcoides burtonii

Acta Crystallographica Section D, Volume 80, Issue 3, Page 203-215, March 2024.
This work reports the purification, biochemical characterization and high‐resolution structures of two novel mevalonate kinases: one from the extremotolerant tardigrade Ramazzottius varieornatus at 2 Å resolution and one from the psychrophilic archaeon Methanococcoides burtonii at 2.2 Å resolution.Mevalonate kinase is central to the isoprenoid ...

Taxonomic diversity of extremophilic prokaryotes adapted to special environmental parameters in Hungary: a review [PDF]

The taxonomic and metabolic diversity of prokaryotes and their adaptability to extreme environmental parameters have allowed extremophiles to find their optimal living conditions under extreme conditions for one or more environmental parameters.
