A halotolerant mutant of Saccharomyces cerevisiae [PDF]

Journal of Bacteriology, 1996
FRD, a nuclear and dominant spontaneous mutant of Saccharomyces cerevisiae capable of growing in up to 2 M NaCl, was isolated. Compared with parental cells, the mutant cells have a lower intracellular Na+/K+ ratio, shorter generation times in the presence of 1 M NaCl, and alterations in gene expression.

Bacteria Halotolerant from Karst Sinkholes as a Source of Biosurfactants and Bioemulsifiers

Microorganisms, 2022
Halotolerant bacteria with biosurfactant (BS) and bioemulsifiers (BE) activity can coexist in Karstic sinkholes with marine influence. Two sinkholes in the Yucatan peninsula were selected to isolate bacteria with BE and BS activity stable in NaCl.

Diversity of culturable moderately halophilic and halotolerant bacteria in a marsh and two salterns a protected ecosystem of Lower Loukkos (Morocco) [PDF]

, 2012
To study the biodiversity of halophilic bacteria in a protected wetland located in Loukkos (Northwest, Morocco), a total of 124 strains were recovered from sediment samples from a marsh and salterns.

Yersinia pestis halotolerance illuminates plague reservoirs [PDF]

Scientific Reports, 2017
AbstractThe plague agent Yersinia pestis persists for years in the soil. Two millennia after swiping over Europe and North Africa, plague established permanent foci in North Africa but not in neighboring Europe. Mapping human plague foci reported in North Africa for 70 years indicated a significant location at <3 kilometers from the Mediterranean ...

Whole Genome Sequencing and Comparative Genomic Analyses of Lysinibacillus pakistanensis LZH-9, a Halotolerant Strain with Excellent COD Removal Capability

Microorganisms, 2020
Halotolerant microorganisms are promising in bio-treatment of hypersaline industrial wastewater. Four halotolerant bacteria strains were isolated from wastewater treatment plant, of which a strain LZH-9 could grow in the presence of up to 14% (w/v) NaCl,

Halotolerance mechanisms of the methanotroph Methylomicrobium alcaliphilum

Biotechnology and Bioengineering, 2020
AbstractMethylomicrobium alcaliphilum is an alkaliphilic and halotolerant methanotroph. The physiological responses of M. alcaliphilum to high NaCl concentrations, were studied using RNA sequencing and metabolic modeling. This study revealed that M. alcaliphilum possesses an unusual respiratory chain, in which complex I is replaced by a Na+ extruding ...

Haloadaptation: insights from comparative modeling studies between halotolerant and non-halotolerant dehalogenases

Journal of Biomolecular Structure and Dynamics, 2019
Halophiles are extremophilic microorganisms that grow optimally at high salt concentrations by producing a myriad of equally halotolerant enzymes. Structural haloadaptation of these enzymes adept to thriving under high-salt environments, though are not fully understood.

Genome analyses of the microalga Picochlorum provide insights into the evolution of thermotolerance in the green lineage [PDF]

, 2018
While the molecular events involved in cell responses to heat stress have been extensively studied, our understanding of the genetic basis of basal thermotolerance, and particularly its evolution within the green lineage, remains limited.
