Acid Experimental Evolution of the Haloarchaeon Halobacterium sp. NRC-1 Selects Mutations Affecting Arginine Transport and Catabolism

open access: yesFrontiers in Microbiology, 2020
Halobacterium sp. NRC-1 (NRC-1) is an extremely halophilic archaeon that is adapted to multiple stressors such as UV, ionizing radiation and arsenic exposure; it is considered a model organism for the feasibility of microbial life in iron-rich brine on ...

Identification of a Sorbicillinoid-Producing Aspergillus Strain with Antimicrobial Activity Against Staphylococcus aureus: a New Polyextremophilic Marine Fungus from Barents Sea [PDF]

open access: yes, 2018
The exploration of poorly studied areas of Earth can highly increase the possibility to discover novel bioactive compounds. In this study, the cultivable fraction of fungi and bacteria from Barents Sea sediments has been studied to mine new bioactive ...

A Genomic Signature and the Identification of New Sporulation Genes [PDF]

open access: yes, 2013
Bacterial endospores are the most resistant cell type known to humans, as they are able to withstand extremes of temperature, pressure, chemical injury, and time.

Microenvironmental conditions drive the differential Cyanobacterial community composition of biocrusts from the Sahara Desert [PDF]

open access: yes, 2021
The Sahara Desert is characterized by extreme environmental conditions, which are a unique challenge for life. Cyanobacteria are key players in the colonization of bare soils and form assemblages with other microorganisms in the top millimetres ...

The biology of habitat dominance; can microbes behave as weeds? [PDF]

open access: yes, 2013
Competition between microbial species is a product of, yet can lead to a reduction in, the microbial diversity of specific habitats. Microbial habitats can resemble ecological battlefields where microbial cells struggle to dominate and/or annihilate each

CULTIVATION CONDITIONS FOR PROTEASE PRODUCTION BY A THERMO-HALOSTABLE BACTERIAL ISOLATE PLS A

open access: yesJurnal Natural, 2019
Polyextremophiles have increasingly been utilised to produce thermostable enzymes with better stability in multiple extreme conditions. This study reports the screening results of four new bacterial isolates (PLS A, PLS 75, PLS 76 and PLS 80), isolated ...

Is there a common water-activity limit for the three domains of life? [PDF]

open access: yes, 2014
Archaea and Bacteria constitute a majority of life systems on Earth but have long been considered inferior to Eukarya in terms of solute tolerance. Whereas the most halophilic prokaryotes are known for an ability to multiply at saturated NaCl (water ...

Community transcriptomics reveals drainage effects on paddy soil microbiome across the three domains of life [PDF]

open access: yes, 2018
Methan ist ein potentes Treibhausgas, das erheblich zum Klimawandel beiträgt. Es wird biologisch ausschließlich durch methanogene Archaeen produziert, welche in anoxischen Böden weit verbreitet sind. Ein Beispiel ist der Nassreisanbau. Dieser trägt 10%

A polyextremophilic alcohol dehydrogenase from the Atlantis II Deep Red Sea brine pool [PDF]

open access: yesFEBS Open Bio, 2018
Enzymes originating from hostile environments offer exceptional stability under industrial conditions and are therefore highly in demand. Using single‐cell genome data, we identified the alcohol dehydrogenase (ADH) gene, adh/a1a, from the Atlantis II Deep Red Sea brine pool. ADH/A1a is highly active at elevated temperatures and high salt concentrations
