Historic buildings are constantly being exposed to numerous climatic changes such as damp and rainwater. Water migration into and out of the material's pores can lead to salt precipitation and the so-called efflorescence. The structure of the material may be seriously threatened by salt crystallization. A huge pressure is produced when salt hydrates occupy larger spaces, which leads at the end ...

BACKGROUND Halophilic bacteria have shown their significance in industrial production of polyhydroxyalkanoates (PHA) and are gaining more attention for genetic engineering modification. Yet, little information on the genomics and PHA related genes from halophilic bacteria have been disclosed so far. RESULTS The draft genome of moderately halophilic bacterium, Halomonas sp. TD01, a strain of g...

Halophiles can be found in hypersaline environments and they synthesize products of industrial interest. Method: In this work, 37 bacterial strains were isolated from the sediment a dried-out maar “Hoya Rincón de Parangueo” (Mexico) on different culture media with 20% NaCl pH 9, while potential extracellular enzymes determined. Results: Eight genera Salsuginibacillus, Alkalibacillus, Bacillus, ...

The marine environment covers almost three quarters of the planet and is where evolution took its first steps. Extremophile microorganisms are found in several extreme marine environments, such as hydrothermal vents, hot springs, salty lakes and deep-sea floors. The ability of these microorganisms to support extremes of temperature, salinity and pressure demonstrates their great potential for b...

We were able to demonstrate that hydroxyectoine, in contrast to ectoine, is a good glass-forming compound. Fourier transform infrared and spin label electron spin resonance studies of dry ectoine and hydroxyectoine have shown that the superior glass-forming properties of hydroxyectoine result from stronger intermolecular H-bonds with the OH group of hydroxyectoine. Spin probe experiments have a...

The Archaea represent one of the three primary kingdoms or domains of living organisms. The alternative name ‘archaebacteria’ is considered by some to be redundant. Archaea are single celled, lacking a nuclear membrane and having a low deoxyribonucleic acid content. They include thermophiles, halophiles and acidophiles, collectively termed ‘extremophiles’. Some believe that they resemble the do...

BACKGROUND Among extremophiles, halophiles are defined as microorganisms adapted to live and thrive in diverse extreme saline environments. These extremophilic microorganisms constitute the source of a number of hydrolases with great biotechnological applications. The interest to use extremozymes from halophiles in industrial applications is their resistance to organic solvents and extreme temp...

The aim of the study was to explore the halophile metabolome in building materials using untargeted metabolomics which allows for broad metabolome coverage. For this reason, we used high-performance liquid chromatography interfaced to high-resolution mass spectrometry (HPLC/HRMS). As an alternative to standard microscopy techniques, we introduced pioneering Coherent Anti-stokes Raman Scattering...

Extreme halophiles offer the advantage to save on costs of sterilization and water for biohydrogen production from lignocellulosic waste after pretreatment process with their ability withstand extreme salt concentrations. This study identifies dominant hydrogen-producing genera species among acclimatized, extremely halotolerant microbial communities taken two salt-damaged soil locations in Khon...

BACKGROUND Extensive use of phenolic compounds in industry has resulted in the generation of saline wastewaters that produce significant environmental contamination; however, little information is available on the degradation of phenolic compounds in saline conditions. Halomonas organivorans G-16.1 (CECT 5995(T)) is a moderately halophilic bacterium that we isolated in a previous work from sali...
