Haloquadratum walsbyi : Limited Diversity in a Global Pond

PLoS ONE, 2011
BackgroundHaloquadratum walsbyi commonly dominates the microbial flora of hypersaline waters. Its cells are extremely fragile squares requiring >14%(w/v) salt for growth, properties that should limit its dispersal and promote geographical isolation and ...

A Differential Metabarcoding Approach to Describe Taxonomy Profiles of Bacteria and Archaea in the Saltern of Margherita di Savoia (Italy) [PDF]

Microorganisms, 2020
Microorganisms inhabiting saline environments are an interesting ecological model for the study of the adaptation of organisms to extreme living conditions and constitute a precious resource of enzymes and bioproducts for biotechnological applications ...

Novel insights into the diversity of halophilic microorganisms and their functioning in hypersaline ecosystems [PDF]

npj Biodiversity
Our understanding of the microbial diversity inhabiting hypersaline environments, here defined as containing >100–150 g/L salts, has greatly increased in the past five years. Halophiles are found in each of the three domains of life.

Succession and assembly mechanisms of seawater prokaryotic communities along an extremely wide salinity gradient. [PDF]

Environ Microbiol Rep, 2023
Succession and assembly mechanisms of prokaryotic communities along an extremely wide salinity gradient. Abstract Salinity is an important environmental factor in microbial ecology for affecting the microbial communities in diverse environments. Understanding the salinity adaptation mechanisms of a microbial community is a significant issue, while most

Determining virus-host interactions and glycerol metabolism profiles in geographically diverse solar salterns with metagenomics [PDF]

PeerJ, 2017
Solar salterns are excellent model ecosystems for studying virus-microbial interactions because of their low microbial diversity, environmental stability, and high viral density.

Genome comparison reveals that Halobacterium salinarum 63‐R2 is the origin of the twin laboratory strains NRC‐1 and R1

MicrobiologyOpen, Volume 12, Issue 3, June 2023., 2023
The complete genomes of four Halobacterium salinarum strains were compared in detail. Two strains (91‐R6T and 63‐R2) were isolated in 1934 by Lochhead from cow and buffalo hides. From the results of these comparisons, we conclude that strain 63‐R2 is the immediate ancestor of the two, widely used laboratory strains NRC‐1 and R1.

Scientific novelty beyond the experiment

Microbial Biotechnology, Volume 16, Issue 6, Page 1131-1173, June 2023., 2023
Practical experiments drive important scientific discoveries in biology, but theory‐based research studies also contribute novel—sometimes paradigm‐changing—findings. Here, we appraise the roles of theory‐based approaches focusing on the experiment‐dominated wet‐biology research areas of microbiology. Theory‐based studies can transcend barriers imposed

Experimental evolution of environmental tolerance, acclimation, and physiological plasticity in a randomly fluctuating environment

Evolution Letters, Volume 6, Issue 6, Page 522-536, December 2022., 2022
Abstract Environmental tolerance curves, representing absolute fitness against the environment, are an empirical assessment of the fundamental niche, and emerge from the phenotypic plasticity of underlying phenotypic traits. Dynamic plastic responses of these traits can lead to acclimation effects, whereby recent past environments impact current ...

Highly integrated adaptive mechanisms in Spiribacter halalkaliphilus, a bacterium abundant in Chinese soda‐saline lakes

Environmental Microbiology, Volume 23, Issue 11, Page 6463-6482, November 2021., 2021
Summary Soda‐saline lakes are polyextreme environments inhabited by many haloalkaliphiles, including one of the most abundant Spiribacter species. However, its mechanisms of adaptation are not ecophysiologically characterized. Based on a large‐scale cultivation strategy, we obtained a representative isolate of this Spiribacter species whose relative ...
